Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This test is a patented test algorithm developed by BioPredictive. It combines 10 standard biomarkers: gamma-glutamyltransferase (GGT), total bilirubin, alpha-2-macroglobulin, apolipoprotein A1, haptoglobin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol, triglycerides, and fasting glucose. These markers are weighted depending on the patient's age and gender.


Testing is compliant with BioPredictive's technical recommendations and approvals.
