Here is a quick follow up to my message of last night.
I've been told that the person I matched had to have his sample retested
(using the sample from his tube B) because of "lab splash" which
contaminated part of a batch of samples.
Moreover, the man I matched did not match with his presumed relative who
also sent in a sample.
So maybe we have to consider the possiblity of a mistake by the lab. Future
testing of additional individuals will help resolve this, but that will take
time and money.
