Which of the following is not considered part of a standard liver panel test?

In the context of a standard liver panel test, creatinine is not included as it is primarily a marker of kidney function rather than liver function. A liver panel typically assesses various enzymes and substances that offer insights into the health and function of the liver.

Albumin, alkaline phosphatase, and bilirubin are all part of the standard liver panel. Albumin helps assess the liver’s ability to produce this essential protein, alkaline phosphatase indicates potential bile duct obstruction or liver disease, and bilirubin measures the liver's ability to process waste products. In contrast, creatinine levels would be evaluated in kidney function tests, making it unrelated to the specific assessment of liver health encapsulated in a liver panel.
