The Man With the Golden Blood 75

Posted by samzenpus from the rarest-of-the-rare dept.
First time accepted submitter Torontoman points out this story of a man with one of the rarest blood types in the world. Forty years ago, when ten-year-old Thomas went into the University Hospital of Geneva with a routine childhood infection, his blood test revealed something very curious: he appeared to be missing an entire blood group system. There are 35 blood group systems, organized according to the genes that carry the information to produce the antigens within each system. The majority of the 342 blood group antigens belong to one of these systems. The Rh system (formerly known as ‘Rhesus’) is the largest, containing 61 antigens. The most important of these Rh antigens, the D antigen, is quite often missing in Caucasians, of whom around 15 per cent are Rh D negative (more commonly, though inaccurately, known as Rh-negative blood). But Thomas seemed to be lacking all the Rh antigens. If this suspicion proved correct, it would make his blood type Rhnull – one of the rarest in the world, and a phenomenal discovery for the hospital hematologists.

As it is (according TFA) he has to pay for taxi fair to the blood donation centers.

    • Why are you thinking of a human/ arachnid hybrid as having gold-coloured blood? Humans (and other vertebrates) have an oxygen-carrying compound called haemoglobin, which changes from a reddish colour when oxygenated to a bluish colour when deoxygenated. Arachnids (mites, spiders, scorpions) on the other hand use a compound called haemocyanin, which is bluish when oxygenated and colourless when deoxygenated. So a hybrid would have blood varying from a dark purple to a bluish colour depending on which side of

    I do find this interesting and would welcome links suitable for the lay person on the subject. But I'm not sure if these blood types are rare or just not something that is usually looked at, and I'm at a loss to understand why and how it was checked and found in this case. I'm used to the four major groupings (A, B, AB (both A and B) and O (neither A or B)) and the main RH factor that determines RH+ or RH-. But I seldom see any mention of special typing beyond this and I don't know if all blood is typed for these special extra factors and then that information is just withheld form patients or if the majority of tests are just for these major 8 categories. I suspect the latter. But that brings up the question of when and why blood is ever tested for all of these other "minor" typings, and just how minor are they. Occasionally we hear about someone who needs extremely rare blood, but the medical world seems to be content to classify me as B+. What does one do to rate these extra special tests?

      It is tested. If you donate once and you're a rare, they'll let you know.

      I'm actually a very common a+ with an unusual antigen (or more appropriately, lack of).

      In the US, when you donate blood, you'll be tested for ABO/Rh, and some of the more "minor" blood antigens (minor insofar as they are less frequently implicated in transfusion reactions and pregnancy-related alloimmunization. Most pregnant women will get, in addition to ABO and Rh-D testing, tested with an antibody screen for sensitivity to antigens from other alleles on the Rh locus, Rh-C and Rh-E. The antibody screen also tests for anti-Kell (anti-K, typically the worst of the more minor antigens; we're taught "Kell kills"), anti-Duffy (Fy(a) and Fy(b)), and sometimes anti-Kidd antigens, and once in a while you'll see anti-P, anti MNS, and anti-Lewis, which typically cause little or no harm. (See this Medscape article [medscape.com] for a few details.)

      The deal is if you are (say) an Rh positive fetus in an Rh negative mom who was previously exposed to another fetus's D antigens (and D is often the culprit) you can get your blood cells nailed by mom's previously-formed anti-D antibodies. You get anemia, jaundice as well, and the potential various bad side effects therefrom (heart damage, brain damage, swelling all over [google.com][may not be safe for work]). Similar havoc ensues with anti-K. Preventive therapy with RhoGAM is available to prevent anti-D disease; it's a soup of anti-D antibodies that scavenge any fetal Rh-D positive blood cells that happen to find their way into mom's circulation. It's produced from pooled human blood plasma, though even most Jehovah's Witnesses (since a 1974 church opinion) and Jews (because there's an escape hatch in kashrut for saving human life) find it acceptable for treatment in order to prevent this fairly terrifying surprise G-d had in store for a few unlucky babies.

      It's because in case of rare blood types, there are subtles anomalies in the standard blood typing process.
      These anomalies lead to more thorough explorations.

      There are enough blood donors around the world, and the testing on their blood is comprehensive enough, that one can make statistical conclusions about the prevalence of certain blood types in the general population. In other words - there's a large enough sample set (hundreds of millions, if not billions, or units tested to date, coming from tens or hundreds of millions of donors) that the (statistical) error bars are very small.

      That's interesting. Some things are the same everywhere. In the US Army we got the day off for donating blood, too. It's a great idea and was one of the few really nice perks. (Side note: every three-day weekend we automatically got a fourth day off. See the Army's not *that* bad, hah).

For me it is something that I need to do to prevent illness as hemochromatosis [wikipedia.org] runs very strongly in both sides of my family. I figure I am doing my self some good and doing other people some good at the same time since if I actually were to develop hemochromatosis I would still need to get drained but the blood would be of no use. As an added benefit I am an universal donor with O- so it is always an in demand donation.
