Evaluation Algorithm

Hover over each oval for more information and select a pattern, duration, and classification. Clicking on the classification will take you to additional information.

The Pattern stage of the evaluation algorithm showing that after an abnormal liver test, the patient will have either predominant elevation of ALT and AST or Predominant elevation of alkaline phosphatase (Cholestatic pattern). Click on the relevant pattern to proceed.Abnormal liver tests
The Pattern stage of the evaluation algorithm showing that after an abnormal liver test, the patient will have either predominant elevation of ALT (SGPT) and AST (SGOT) (Hepatocellular pattern); or Predominant elevation of alkaline phosphatase (Cholestatic pattern).
