Type 5b acid phosphatase test; TRAP test

There should be less than 5 nanograms per milliliter (ng/mL) of TRAP.
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What abnormal results mean
A high level of TRAP in leukemia cells supports a diagnosis of hairy cell leukemia.
A high level of TRAP in the blood plasma is a sign of bone breakdown. This can be due to many types of diseases, but in a patient with cancer it is likely a sign that the cancer has spread to bone.
