My mother died from primary bilary psorosis when she was 66. My Aunt is now dying from the same disease, she is 78. What tests can be done to find out if I and my siblings, children, cousins, etc have this disease. I was told that a simple blood test was sufficient, but I was also told that a chromosome test should be done. What are my options. While I know that there is no cure, is a liver transplant the only answer? Please give me any and all information any of you have.

Thank You

Trish
