Correlation of Blood Gene Expression (TruGraf Liver) With Liver Biopsy in Pediatric Liver Transplant Recipients

Correlation of Blood Gene Expression (TruGraf Liver) With Liver Biopsy in Pediatric Liver Transplant Recipients

Liver transplant rejection is when the body's immune system attacks and damages the liver of a transplant recipient. Currently the best way to see if that is happening is with a liver biopsy. The purpose of this research study is to see if a simple blood test can diagnose if a transplanted liver is being rejected.

This study is an investigator-initiated, prospective, single-cohort trial to assess the ability of the TruGraf® Liver gene expression panel (GEP) to predict rejection in pediatric liver transplant recipients undergoing surveillance and for-cause liver biopsy.

Inclusion Criteria:

• All liver transplant patients at least 1 year of age and less than 18 years of age undergoing surveillance or for-cause liver biopsy

Exclusion Criteria:

• Non-English, non-Spanish Speaking
