It’s a family donation. They aren’t asking to be put on the donor list.
This is one of the many problems I have with this story. They don’t have a donor until a lot of tests are done and that can take months. They don’t start testing for a compatible donor until after the recipient is approved for a transplant.
To simplify this as much as possible, there are two main limits to being medically approved for a transplant:
1)You have to be sick enough to need a transplant, and
2) You have to be healthy enough to survive the operation and the immune system suppression necessary to prevent the rejection of the new organ.
These limits are absolutely necessary and in this country they trigger even more rejections than the lack of money to pay for the surgery. A lot of people come to the hospital already too sick to benefit from a transplant. It is very possible that the girl in this story falls into this category.
I know the process to be approved as a living donor because I went through it with my sister. It starts with a medical history questionaire. Some of it is obvious. You have to be in excellent health. If you have a personal history of heart disease, cancer, or stroke, you cannot be a living donor. If you have high blood pressure or diabetes, you cannot be a donor. If you have ever had kidney disease, including kidney stones, you cannot be a donor. If you have had any serious viral disease like HIV or hepatitis you cannot be a donor. If you are a smoker, you are urged to stop for at least several months before the surgery. If you have a history of substance abuse, you will probably be rejected.
If your medical history is satisfactory, you have your blood pressure tested and get a simple ABO blood typing. If the blood type is compatible and the blood pressure is normal you move on to another round of testing. This involves four vials of blood that totals almost as much as blood donation. It was enough that I was dizzy when I got up. I had to sit in the hospital lounge with orange juice and some crackers for about 20 minutes before I could drive myself home. I never saw the bill for the testing, but I bet I could have had a full meal at a first class restaurant for what the hospital charged for that OJ

. One of these blood tests involves mixing the blood of the prospective donor and the prospective recipient and waiting to see if antibodies develop over a few days. This test cannot be done with cadaver kidneys and is one of the reasons why a match from a living donor has a better success rate than a match from a deceased donor. It was this test that determined I could not donate a kidney to my sister. If I had died in an auto accident, they would have used my kidney and it would have been rejected. The reaction to my DNA was probably caused from a previous blood donation my sister received 15 years before for a totally different problem. In 1991 there was no really accurate test for HIV and donations from known blood donors were considered important.
If you pass all the blood tests you get a comprehensive physical exam and CRT scan to see if your kidneys are normal and in the right place. Only if no problems are discovered in this phase are you ready to be a donor. If either donor or recipient have a cold or minor infection, the operation will be delayed until those are treated.
Having a large family is not as big an advantage as some think. My sister had four brothers and two children. The children had their father’s blood type and could not be considered. All four brothers had the same blood type, but I was the only one healthy enough to pass the questionaire phase. It is common that the reason someone needs a kidney transplant in the first place runs in families, whether it is genetic or envrionmental.
