@mnjp0623, The time allotted to arrive at the transplant center when you get the call is a difficult one to answer. So much depends on patients distance from hospital. I am a patient. Here is my an example from my experience:
I was initially listed with my regional liver center in Kentucky. When my husband asked the same question, the doctor asked him how long it took us to drive to the clinic (45 minutes) so the doctor told us that would be okay. Later, after I was transferred to Mayo in Rochester, we lived at the Gift of Life Transplant House which was several blocks away from the hospital. So the time of arrival for us was never really discussed and the transplant surgeon just told me to come on in to the hospital where nurses would be waiting for us.
I have heard of patients having 4 hours to drive, and even one patient who saw her organs arrive via med helicopter at the same time that she was arriving!
I wish that I could give you a precise amount of time, so much is going to depend on how far away you are living 'and the mode of transportation you will be using.

I know how anxious you are as you are looking toward your own call about your future liver transplant. Your own transplant team will be able to provide the best answer to this. When is your next appointment? Have you asked your own transplant team about timing your arrival?
