We've been waiting prenatally to see what baby's blood type is in order to be able to plan a bit ahead for the needed liver transplant.
Baby's blood type is B!! You might ask why I'm excited to hear this. We knew that the blood type would be either O or B, based on the blood types of myself and my husband. It was a 50/50 chance either way. Here are the statistics on why this is good news. (The +/- factor has no influence on liver donations, and the lab report didn't specify +/- anyway.)
In Canada, 46% of the population have an O blood type (39% O+, 7% O-).
In Canada, 9% of the population have a B blood type (7.6% B+, 1.4% B-).
Being B, he can receive a liver from someone who is either O, or B blood types. It slightly raises the number of potential people that he can receive a liver from than if he was O, since O can only receive a liver from another O.
From the opposite perpective, someone who is a B blood type, can only give to someone who is B or AB (AB is a total of 3% of Canada's population), whereas O can give to anyone. So if a B blood type liver became available, there are less people that it can be given to...only B or AB blood types.
The fact that baby is a B blood type slightly lowers the waiting time involved for receiving a cadaver liver than if he was an O blood type.
Ok, so I know that most people won't be nearly as excited about this piece of info as I am, but it's a step in the right direction for us!
If you happen to be interested in applying to be a donor, let me know, and I'll send you more information.
