Matt's Aunt finds out her second series of blood tests look promising and heads to the University of MN to meet with the transplant team.  They complete some physical exams and determine that there are a couple of concerning risk factors:
1. She has high blood pressure.
2. She may be prone to developing kidney stones.  She has had a lap-band procedure and there is a new study that has found that people who have undergone that procedure are more likely to develop kidney stones.
The donor work-up is a two day process, but due to an unfortunate miscommunication she only knew about one day of testing and had to return home unable to complete the second day of testing.  Due to the above risk factors, it is unlikely that she will be considered a good candidate for donation. 

Matt is disappointed to find out that his aunt may not be considered a donor candidate.  It becomes almost scary to have hope because if it doesn't work out, the hurt of the let down is so great.  A lot of things need to line up in order to find a compatible donor, but it will happen and the day he gets that phone call will make it all the ups and downs worthwhile.
