(1) Blood tests showed raised levels of aspartate transaminase , alkaline phosphatase and bilirubin, confirming liver damage.(2) the activity of aspartate transaminase(3) Aspartate transaminase is an enzyme that plays a role in many aspects of body metabolism.(4) Liver function tests routinely combine markers of function (albumin and bilirubin) with markers of liver damage (alanine transaminase , alkaline phosphatase, and glutamyl transferase).(5) Mild elevations in liver chemistry tests such as alanine transaminase and aspartate transaminase can reveal serious underlying conditions or have transient and benign etiologies.(6) Concentrations of serum creatine kinase, transaminases , urea, and creatinine may be raised, and bicarbonate may be reduced.
