I was told they take your highest Meld score and go off that. They were draining between 9 and 12 liters every week for 3 months from me. I would gain 25 lbs and then lose it once drained. My Meld score got as high as 28 or 29. When I received my liver in Phoenix, i was on list 30 days. I am also blood type B which they said helped as that put me at top of list for that blood type. When i had my transplant, my meld was in low 20's but the draining was taking toll on kidneys and rest of body.
