Although an abnormal aspartate aminotransferase (AST) or alanine aminotransferase (ALT) level was predictive of liver disease (HR=4.2), the rate of detection was remarkably low, with only 3.9% of those with an abnormal value being diagnosed with significant liver disease within 5 years of the test.12 Thus, used in isolation, liver blood tests are neither specific diagnostic tools nor specific exclusion tools,13 whereas they can be more effectively used to assess the extent of liver fibrosis if incorporated into algorithms14 or used in conjunction with other modalities.15–18. Here, GPT is linked to Hepatic fibrosis.
