Two negatives make a positive – donate blood


I gave blood last week, it was my fifth donation so I got a neat little lapel pin that is a blood drop with a 5 on it. But more interestingly I learned that my blood is  O negative and CMV negative. At first this didn’t mean anything to me, but the nice lady explained that CMV refers to Cytomegalovirus, a virus that about half the population carries and is harmless because antibodies are developed etc.  And the Rh O Negative means I am a universal donor – anybody can use my blood.

It is considered somewhat rare. Only 7% of the population is O Negative. Approximately 20% of the population is CMV negative. So only about 1.4% of the population is O Negative CMV negative. That is fewer than 2 our of ever 100 people. It isn’t the rarest, but it is a very useful type.

However, the CMV blood can’t be used for babies, either premature or just very young as they have yet to develop the antibodies. So all this to say my blood is used for treating babies, and as I am a universal donor I am in high demand!!

I know that two wrongs don’t make a right, but in this case two negatives make a positive!!

By the way, don’t forget to donate blood, especially during the summer when folks go on vacation and supplies run low.
