How do you prepare for an alkaline phosphatase test?

ANSWER

This test checks for an enzyme in your blood that might show if you have a problem with your liver. You may have to limit food and liquids for several hours before the test. Some medicines interfere with the results, so tell your doctor if you're on any medication and supplements. Be sure to let your doctor know if you are pregnant, because that will raise the level of alkaline phosphatase in your blood.
