The Pleximmune test is the first blood test of its kind to predict whether acute cellular rejection will occur in children with liver or intestine transplantation. This information can help transplant physicians guide post-transplant care. During a six-year period, over two hundred and eighty blood samples from more than 200 children were tested in two groups. Samples from the first portion of the study period were termed the training set, and those obtained subsequently were termed the validation set.
