This test measures Alkaline Phosphatase (ALP) in the blood.  ALP is an enzyme primarily found in the cells of the liver and bones. Elevated ALP levels are typically indicative of liver or bone damage.  High ALP is normal in children whose bones are still growing. 

This test is often ordered as part of liver function testing to aid in the diagnosis of liver disease or monitor treatment.  When ordered by itself, ALP is often tested with GGT to help differentiate between liver and bone disorders.  While ALP may be elevated in cases of liver or bone disease, only liver disease will cause elevated GGT levels.

An ALP test is also included as part of a Comprehensive Metabolic Panel and a Hepatic Function test.

Turnaround time for the Alkaline Phosphatase test (ALP test) is typically 1 business day.
