A GGT blood test, also known as Gamma-glutamyl transferase or Gamma-glutamyl transpeptidase, (GGTP) is a laboratory test used to screen the patient for possible liver damage and/or suspected alcohol abuse. Although the test can detect elevated levels of GGT, it is typically not successful in determining the cause.While increased levels may be an indicator of various damages to the liver, the test itself is not sufficient enough for diagnosing a liver condition.lthough the test can detect elevated levels of GGT, it is typically not successful in determining the cause.
