What is this test?

This is a deprecated qualitative liver panel that screens several substances associated with liver function, including liver enzymes, bilirubin, and albumin. It may appear in older records, but current liver testing is usually performed with numeric measurements.

Why might I need this test?

It may have been ordered to investigate suspected liver disease, medication effects, alcohol-related injury, or another condition that can affect the liver. A current quantitative liver panel and clinical evaluation are usually needed to assess the results.

How is the test performed?

A laboratory analyzes a blood sample for the selected liver-related analytes. Because this version is qualitative, it may report whether findings are normal or abnormal rather than providing precise values.

How do I prepare for the test?

Fasting is usually not required for routine liver testing, but follow any instructions provided with the order. Tell your clinician if you drink alcohol regularly or take medicines that may affect the liver.

Reference range

Adult: 10-40 U/LN/A
