Description

The total alkaline phosphatase (TAP) test is a laboratory test used to measure the amount of alkaline phosphatase (ALP) in a patient's serum. ALP is an enzyme found in the liver, bile ducts, and bone. Elevated levels of ALP can indicate a variety of conditions, including liver disease, bone disorders, and certain types of cancer.

The TAP test is performed by collecting a sample of the patient's blood and then measuring the amount of ALP in the serum. The sample is usually collected through a venipuncture, where a needle is inserted into a vein in the arm and a sample of blood is drawn. The sample is then sent to a laboratory for analysis. The laboratory will measure the amount of ALP in the sample and report the results to the doctor.
