5yr old me when my doctor said my O- blood can save lives when I get older: *I...am the chosen one.*

I like that in Sweden you get a text whenever your blood has been used

Canadian here. Lived in Australia for ten years. I'm A- so kind of rare but can be swapped for other types so not so bad. Was donating blood a lot there, and one day I got a call. Turns out as I was Canadian I hadn't had some typical Australian disease that created a dangerous condition for babies receiving blood. Since I wasn't Australian they wanted my blood for a baby that was in need of an operation. So as soon as I donated, the blood was off to the hospital. It was the first time in my donating history that I felt a real connection to a donor, and it drove home how important blood donation was.

I'm an RN and I have heard of rh null before, but this is the best YT video I have seen with the most information. RH null is so fascinating but so difficult for those who have it. I admire those who donate and don't blame those who don't. I have never received a transfusion but think of all the units I've given over my career, I have no idea how many. I worked in ICU and trauma, so lots. My deep thanks to the donors, you have made a real difference in people's lives.

Someone: "what's your blood type?" 5 year old me: "red"

A girl I know has a rare genetic condition that causes her to produce way too many platelets and red blood cells. They only treatment is for her to donate blood. She generally donates every 2-3 weeks to stay healthy. She has saved countless lives while also saving her own.

I am related to someone who is RH-Negative and they absolutely refuse to donate blood because it's 'their blood'. It got to the point that they were paranoid about going to the doctor and having their blood 'stolen'. And yet, that same person needed a surgery once, but there was no blood for a transfusion and it was a mess. So glad I've got one of the most common blood types.

I'm A-, and as such my red cells are high demand. So high, they always do what is called a double red donation. They hook you up to a machine just like what is used for dialysis and just keep the red cells, returning everything else, plus adding saline to make up for volume lost. To do a double red, your hemoglobin count needs to be over 14.8, preferably closer to 16. You can only donate every 4 months and every 4 donations you need to skip the next 2 before being able to donate again. Even with the high hemoglobin count, it takes a lot out of you and can take 2 to 3 weeks before you feel back to normal. It's recommended to binge on high iron foods for up to a week before and at least 5 days after donating a double.

In a nutshell, donate your blood because you might save your own life.

Almost 60 years ago, when I was an infant, I needed AB- blood. A man came from halfway across Texas to where I was in the hospital in Houston, to donate for me. I wouldn't be alive and enjoying my first grandchild, if it hadn't been for that man. To those who've commented that my blood donor driving across Texas in 1963 was ridiculous, since AB- can receive A-, B- or 0-, my mom said that the doctors insisted on it because I have some sort of weird antigen or factor, and that as I'd nearly died several times during those 6 weeks, "close enough" wasn't something they were willing to risk.

I’m O-Positive. I started donating blood the day I turned 16. With various pauses I have donated over my entire life. I’m 60 now. I have given both whole blood and platelets since the age of 20. My beef with giving platelets is that if you give two units of platelets at a time, it only counts as one donation. 3-4 hours on the machine for 1 donation. It should count as two. Most of my platelet donations have been doubles where I’ve matched a patient needing platelets. It gets a tad bit irritating when you spend so much time and don’t get the proper credit for your time. They should at least credit you properly two for two.

This video is so simple, yet so packed.

I donated blood once they told me I was O-neg. A few weeks later the people sent me a letter with a card from the parents of a little boy that was in an accident. They said my blood was used to save his life and wanted to thank me. I will never forget that card.

This channel is like the version of real life engineering that I can actually understand and not feel dumb

Years ago I worked as a Cardiovascular Unit nurse. We admit patients scheduled for bypass. We have a checklist we follow to make sure the surgery goes smoothly the next day (usually, these patients come in a day prior to the procedure). Loads of stuff we have to do; making sure they have all the blood works done, their medications and history properly listed, ECG and other test results ready at hand (especially the copy of their recent angiogram!), inform all the doctors that are going to be involved that the patient has arrived so they can all do their rounds before the actual procedure (mind you, there are LOADS. They will have a complete line-up including the cardiothoracic surgeon, the cardiologist, the cardiologist who will perform the intra-op transoesophageal echocardiogram (TEE), a pulmonologist, a nephrologist… you name it. Not to mention, they will immediately go to CCU post-op so they will be under the care of an intensivist too). Besides these, we have to complete the necessary paperwork and phone calls. The most important is making sure that we inform the lab and ask them to prepare 4 units each of PRBC, FFP, and platelets. CABG is a big surgery, so those units are just the required BARE minimum. I admitted a patient for said CABG procedure and I was working nights. Working a night shift with a pre-op CABG patient is pretty hectic because you’re tasked to make sure that everything is complete. One of those things is making certain the 4 units of each blood product required are complete and reserved for the patient that night. This patient of mine came in and my whole night had been non-stop phone calls and updates from the lab. He’s O- and his blood type was so rare that the lab couldn’t complete his blood units on time. The procedure was then cancelled because we couldn’t find the rest in time for the CABG. I remember getting so tensed throughout the shift just wishing they’d find him more blood. But life works in mysterious ways. It was his saving grace. The holding of the procedure saved his life. Turns out, the morning he was supposed to have the bypass, he suffered a stroke. I distinctly remember passing by his room and apologising we couldn’t get his blood on time, and him still being light-hearted about it. I also distinctly remember, as I was on my way out of the hospital, I heard the hospital speaker system saying “Brain Attack Team to CVU, now”. Turns out, he was that patient. Just thinking about it gave me goosebumps. Imagine if we got the blood and he underwent the procedure that day, he would have suffered a stroke on the table and most likely he wouldn’t have survived. After the stroke, he stayed in the hospital for more rehab until it was safe for him to get the bypass. I am pleased to say he survived. ❤

I remember seeing a story of a guy who was 80 at the time who had rh null blood. He donated blood as often as he could safely it was every few weeks I think. He saved so many lives

When I was in my twenties I was matched to a child with leukemia. Every time this child has surgery scheduled I was called to donate blood or bone marrow. The calls came closer together one year then stopped. The Red Cross couldn’t tell me why but it was obvious.

Man people with rh null surely is have burden same like a superhero they must make a life or death choice if there is a request for their blood.

Glad that AB positive is so helpful and useful. I am blessed with such.

My son had severe aplastic anemia . It was so severe that he needed blood every 4 days for almost 8 months . Luckily his bloody type is AB+ this past February has had to have a bone marrow transplant , I was his half match donor and same blood type . I am really grateful for all the blood he had received from all who has donated ❤

I hope this channel too grows like Real Engineering !

I asked my doctor what blood type I had. She said she wasn’t allowed to tell me. Like wtf, it’s my blood

My mother had RH Null. She almost died on 3 separate occasions because of hemorrhaging and had to have blood flown in from all over the east coast and luckily survived before running out of donor supply.

I'm Rh negative and had to get the rogam shot while pregnant. Could the Rh factor's effect on pregnancy possibly be covered in a video please? Also, I find it interesting that few people actually know what their blood type is when it could be important. I think people need to be aware of why it's important to know what blood type they have, mostly to avoid any complications

"what's your blood type?" "The type that goes in my body" *Omg same*

Donated 18 gallons before I lost a kidney to cancer. In 3 more years I'll be cancer free and maybe I can start again. 🙏🇺🇸

I don't know my blood type, and have always wanted to give blood since I was young. Unfortunately I was informed I was legally not allowed to give blood because I had ALL Leukemia as a child and fell under the blood disease/disorder clause for donating blood. It broke my heart when I found that out because I have always wanted to give back for all the blood transfusions I received as a child.

Having work for the Red Cross in the blood distribution, I would love to see a further video on the difference between packed cells, serum, and derivatives such as platelets. I think people would be interested in that. And that you can donates only red cells are only platelets without losing your own blood volume. And platelets are definitely needed as they have a pretty short lifespan outside the body. Platelets are basically your clotting factors in your blood that keep you from bleeding out if you get cut. So you can see how important they are in surgeries.

So having this "golden blood" is like a blessing and a Cursed at the same time

My father is one of them 43, he gave blood to dozens of people during his life, God bless him

My daughter has this blood type. 😔 We discovered this when she was only a few months old and took really sick. The doctor's had her in a sterile room that you could only enter with a full sterile suit, glove's, and foot covers. Once they discovered her blood type, they immediately placed her on double vitamin's. And now that she's grown, she has to give blood to the bank near her every month. At the time, 2003- it was stated that there were only 7 other ppl in the world with her exact blood type and it's kept in a vault. This woman is NOT joking. My daughter can only receive blood from a direct match. Till this day I have no clue how she ended up with golden blood. She's my only daughter, and she's vowed that she won't ever give me any grand children. The doctor's told her that her body will attack the embryo. I've volunteered to carry my grandchild for my daughter so that she would be able to still have a chance at motherhood. 😔She turned me down. I've been blessed to have a beautiful lil girl who can donate to anyone but sadly can't recieve it from just anyone. 😢

I remember the first time I have blood & got a text saying it went to some private hospital that does cosmetic surgery. Really weird vibe but didn’t put me off

Manny: Hey can you don- Jessica: -Sorry, you're just not my type.

As a O neg. donor it has always been an honor to be able to help people. But the hospitals who charge the recipients huge sums for the blood I gave makes me angry beyond words.

I recieved donated blood during a transfusion in 2003. I had suffered an excruciating miscarriage and was hemorrhaging after being sent home from hospital. I went back and was on the verge of death when they finally agreed to sedste me and do a d&c to remove the massive clot that had formed. I remember hearing my heart beating and feeling my pulse througjout my entire body. The next time I got pregnant, they found irregular antibodies in my blood from the previous transfusion. The doctors kept a close eye on it through the pregnancy but luckily everything went smoothly and my beautiful daughter was born perfectly healthy. She is 18yrs old now and in college. Im forever grateful for that blood!❤

im a blood banker, and have dealt with patients with extremly difficult transfusion needs. its amazing see how things get called out and units can be found and brought in from far away. you'll also know that if a patient has no anti D, and is rh negative. we can give rh positive blood to them in trauma situations where massive ammounts of blood are needed. If blood type is unknown, men tend to be given ) O positive blood, and women over 55 as well. Women of child bearing ages are given O negative blood in any emergency.

Them: Why are you so negative all the time? Me: ......I’ll always b-

When my dad worked in Cornwall, England for a while, like 45 years ago, he is a pediatrician, there was a baby who needed blood and was RH Null blood type. They had to get someone all the way from Italy to donate blood. Just thought I would share!

I have a family member who's RH- they had to donate blood for their own surgery a few weeks in advance because of how rare it is.

I’m in UK and am O- so I give blood as much as I can and the transfusion service call me to make an appointment to donate if I don’t rebook. My donations are always coded to go direct to the premature babies (the code is on the bag that is filled). I feel honoured to be able to help. The weird thing is that my mum was O+ and so is my (unidentical) twin sister 🤷🏻‍♀️

In our family, my mother is A and my Father is B. And all 4 of us siblings are AB. What a nice distribution

There should be a compensation system for those with golden blood given the pressure to donate that they constantly face

I don’t know my own blood type cuz the nurses said they can’t tell me and I have to request a certain way 🗿

And the most mess up thing here that wasn't mention is that Hospital charge patient load of moneys for the blood that was donated.

O- is literally the definition of "All for one and one for all"

Their gamemode is set to a level higher than hardcore...

I hated my early life because of having this blood type. Never allowed to do anything that had any risk of injury. Had an aunt who would babysit me as often as possible so she could sell my blood without my parents knowledge. Any doctor visits usually had staff lie to my parents and take blood for bogus tests. I did at least luck out with having several mutations that let's me heal ridiculously fast and my blood cells are pretty robust and can donate frequently. To my parents dismay I love riding motorcycles and a friend I was riding with crashed. We were far away from any major hospital and he needed blood because he lost so much in the accident. This little emergency place had no means to get any so I broke my rules of not staying quiet about who I was (nulls are very known to the relevant people) and donated to help him. His was fairly rare itself and no one present could help. I am basically on call for my blood but I do answer that call whenever possible because so few can. It was a curse but later in life it became a blessing at least to me.

In the UK you donate blood for free. It's voluntary. All you get is a cup of tea and a biscuit as your reward.

There was a man in Australia who gave the golden blood to new borns he had an exemption from going to war, by the time he was in his 80s the Dr told him he couldn’t anymore because of his age he was so sad about that. You can actually read about him .

When I was little I was very proud of having A+ blood type cause I thought that means I m a good student Edit: omg Soo many likes! Thx

Most of my life I thought I was A+, so when I was pregnant with my daughter, that is what I told my obgyn. For some reason my Doc didn't believe me and wanted to get my blood tested. I kept telling him after I was born my parents were told A+. I kinda fought him on this til he told me he has a gut feeling that my parents (who were there with me at this appointment) and I were told wrong. My mother than told me to get it done and it doesn't hurt anything (My mother is a big believer in listening to gut feelings). I did the test and boy do I owe him for pushing me, because it saved my daughters life. When my Doc came back out, he pulled my parents and I in a private office and revealed that I am O-. My parents were mortified (lots hugs and sorries were given after the app.) and my Doc then told me I had to get the Rh immunoglobulin shot. For those who don't know you get this shot to prevent my neg blood from possibly hurting/killing my baby if she is born positive, and as luck would have it, she is A+. My husband is A+. So when pregnant and not sure what your blood type is, or if your obgyn has a gut feeling, get your blood tested.

Do i need to go fins out my blood type before i donate or do i just donate and th3y figure it out after

My brother and I both have A+ blood. We had an almost perfect match (4 out of 6 antigens matched) when I donated one of my kidneys to him 24 years ago. We are both in good health today!

Whatever you do, always give 100%. Unless you’re donating blood.

Wouldn’t ab+ or is it ab- be able to donate the blood that would save the person I know one of the ones can like donate blood to every type or something like that

"Being rare is dangerous"

AB+: all for one O-: one for all

Survivor today because of a donor, thank you all donors.

I want to know the background tune in this video. Please anyone tell?

I’m a gold blood and yes I donate to my self but I’m also very anemic so it’s for myself or to save as many as possible. I don’t know what is so gold if feels more like I’m an alien or cursed lol I did find it interesting that one of the others is in Switzerland and wondered if he’s originally from there as well as his family. My ancestors are or Scandinavian descent so this is curious

Very interesting, had no idea that blood was categorized beyond ABO+- and how much it mattered.

Nobody: People with RH null when they get hurt: *WHY DO I HEAR BOSS MUSIC*

how about weak d variant systems that causes to shift Rh value when blood taken from body to a test tube, e.g., negative to positive?

O- here. I worked at a plant that had the blood mobile come several times a year. We always tried to be there those days. Always a privelidge

People with RH Null: [Chuckles] I'm in Danger.

Me: hey! I got a A+ on a test! Mom: which test? Me: BLOOD TEST!!!

40 years ago I had transfusion to save my life but suffered severe clotting, heart attaccts and almost lost one leg. I was a donor RhAneg. Now am 70 and experiencing all negative symptoms😢

I have a female friend that’s Romanian but lives in UK, she’s also Rh-Null and she has two ID’s for safety of her life, she can’t even work in public to protect herself, the Romanian government gives her monthly salary as if she worked for the state!

Meanwhile I thought my O+ blood was the deadliest as I keep getting attraction from mosquitoes.

Mine is B+ tho ''Be Positive'' :)

When you see a channel called "real science", I would be extremely leery of the content.

I have type O and I get calls to donate and due to me having had cancer I can’t donate. I feel so bad about it because I get calls regularly because it’s in need . I don’t know if that’s how they like get you to come in or if it’s like true but it tugs at the heart strings a bit because they won’t let me.

I’m alive today because of blood transfusions. I’m a two time survivor of Hodgkin’s Lymphoma which is a type of blood cancer and I needed so many transfusions to beat the cancer that I lost count. I want to donate blood and other blood products so badly, but I’m not eligible to donate blood due to having had blood cancer. Instead of being able to donate myself I became a junior ambassador for Red Cross Australia when I was in high school, in one year I was able to get around 150 people to donate blood at least once by sharing my story, having a living example of why donating blood is so important right in front of someone helped people that wouldn’t have donated because of something like a fear of needles to overcome their fear to save lives.

People with type O blood: *_I guide others to a treasure I cannot possess._*

I also have had an issue getting an answer and it's not listed in my online chart.

Me : Mom, dad look i got A+ on my test? Mom and dad : which test? Me: Blood Test!!

That moment when you don't know your blood type then you ask your parents and they don't know what it is either.

How many Rh null people are in the US? Any way to find out?

I gave for ten years regularly. As A+ I was not in high demand, but I gave platelets instead of whole blood. When I moved away from the location that handled these transfusions well I could not find another. It became a true hassle. I never understood why one institution could handle blood donation so conveniently when most others make it a royal pain. I now donate whole blood when I see the mobile blood drives and have the time. But it is only once or twice a year at best.

I have chronic anaemia, and I urge everyone to donate blood if permitted. Without those unnamed generous strangers, I would probably not be alive. Your blood can and has saved millions of family. I thank each and everyone of you Heroes who have donated !!

When you found out that you have a dangerous blood type: *Cha Cha real smooth*

I always assumed the most dangerous blood type was vampire.

Thank you to all of the blood donors! You gave my mother eight more months of life.

When you got all your grades A+ but your blood type is B-.

And to think, my A- is called rare. I couldnt imagine RH Null. Never heard of it til now, very interesting video and work.

I have to collect my own blood for my own surgeries....R.H-

Informative.

*When you can't remember what your blood type is*

I have O+..the nurses look at me like they are vampires. It scares me, lol.

I have RH null. I had 3 surveys many years ago. They had to go 3 hours to find my blood while I was under and they were actively doing the surgery

I have Von Wilebrands Disease variant that they ecnore also don't test for and I have get blood transfusions with the Von Wilebrands Proteins transfusions and the antibodic too or My body doesn't keep the blood. When I was young they had to get my dads blood for me because they used up all they had on me and still loss blood. IN july 2022, I had to get two transfusions because they didn't give me the proteins needed they thought I was kidding or something

Theory: there is someone with rh null that is kept near the president at all times to assist in case he needs a transfusion

Alternative tittle: > The World Rarest Blood > The Most Unique Blood in the World Edit: I changed precious to unique because it seems more fitting(check the reply). I just give some other tittle that might give people a better idea about the video content and thanks for bearing my poor English:-)

They only discuss Antigen D and Rh Null in the video, but the Rh factor disease newborns can experience causing them to often need to have a complete transfer of blood, can happen in other antigens. I am A- (missing the D antigen). However, I may also have a missing E antigen, as my daughter is A+, but was still sensitized by the time of her 4th pregnancy by the missing E antigen. Her baby had Rh factor disease, with dying blood cells because her sensitized cells had passed the placental membrane. He lived under the special light, received numerous units of blood, and when he was six months old had to finally have all of his blood replaced.

I’m A- and my mom is O- she always tells me her blood donation stories it’s scary she can only receive O- but also lucky she can help anyone

Doctor: There are 69 different type of blood Vampire: Blood is blood

Me: *has AB+ blood and never has to worry about access to blood in case of an emergency* That Swiss man: 😡

Now I know why my life changed over the summer.... Literally my blood went missing from the doctor's office or lab and there network went down for a month.

Do you have some tips on how to design an L-R crossover with Xsim?
