- Although, it is extremely uncommon for a patient with hepatic failure to become pregnant due to the pathological effect of hepatic failure on the reproductive system, the policy of Liver Transplantation Service at UPMC is to advise young female not to become pregnant while waiting for OLT. In addition the majority of the patients on the liver transplant waiting list at this institution are above 50 years of age. However, when a female patient of child-bearing potential is called in for OLT and there is a suspicion that she might be pregnant, a blood pregnancy test will be performed as a part of the standard of care for these patients.
