The test that directly indicates jaundice is bilirubin, not an enzyme.

From this report:

Jaundice often becomes visible in the eyes/skin when total bilirubin reaches about 2.5-3 mg/dL, so this is very close to that range.

The relevant enzyme is:

High direct bilirubin + ALP, with normal SGPT/ALT (19.5) and SGOT/AST (33), suggests a cholestatic/obstructive pattern, meaning impaired bile flow. Causes can include a bile-duct stone, narrowing/blockage of a bile duct, medication-related cholestasis, or other liver/biliary conditions. A high ALP supports this pattern but does not itself diagnose jaundice. Merck's jaundice guidance notes that bilirubin fractionation and ALP help distinguish cholestasis from liver-cell injury.

Also important:

Please contact the treating doctor promptly, ideally today or within 24-48 hours. They may consider repeat liver tests including GGT, an abdominal ultrasound, medication review, and tests of liver clotting function (PT/INR). Seek urgent care now for fever/chills, severe right-upper abdominal pain, vomiting, confusion/drowsiness, very dark urine with pale/clay stools, or worsening yellow eyes/skin.
