This is a very interesting article, I thought. Seem that we all know about the blood types A, B, and O and we may also know about the Rhesus type (positive/negative) that together gives us the A+, A-, B+, etc. This has been used for years to match donors with transplant recipients, but there's still a chance that the body would reject the transplant. Scientists now may have found out why.
Seems they've discovered an additional TWO typing structures for blood - Junior and Langereis. I don't know what designates they'll use when typing, but it would mean instead of being blood type B+ (which I am), I'd be type BJL+ (for example) and a better way to match the donor with the recipient.
I don't know how interesting you'll all find this to be but I, for one, think this is a huge leap forward for medicine. It'll play hell on the blood banks for a while and supplies will be low at first as we determine which subtypes are more rare than others, but it's going to be a Godsend for some who are on the donor waiting list.
