I researched it—heart and lung transplant recipients have to have biopsies too. Heart transplant recipients have the highest rate of rejection, for solid organ transplants. It seems that as long as our liver enzymes are within normal range us liver transplant recipients don’t have protocol biopsies. Pancreas transplant recipients also have labs monitored as it’s apparently difficult to biopsy a donor pancreas.

Stem cell recipients have their chimerism levels monitored, which is the state in which donor cells have durably engrafted in the recipient. Wonder what @loribmt can share about that?

One third of all organ transplants are lost to rejection though, so I’m guessing biopsies are a good thing, especially in more recent transplant recipients.
