Definition Lipase is a protein ( enzyme ) released by the pancreas into the small intestine. It helps the body absorb fat by breaking the fat down into fatty acids. This article discusses the test used to measure the amount of the lipase in the blood. How the test is performed A blood sample is needed. For information on how this is done, see: Venipuncture . How to prepare for the test Do not eat for 8 hours before the test. Your health care provider may ask you to stop taking drugs that may affect the test, such as: Bethanechol Birth control pills Cholinergic medications Codeine Indomethacin Meperidine Methacholine Morphine Thiazide diuretics How the test will feel When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation.

[Humor] We're all familiar with -- or should be familiar with -- the standard lab tests to assess our diabetes control. You know, the hemoglobin A1c, the lipid level tests, blood pressure, kidney function tests, and so forth. Sometimes it seems as if every time we work hard to get our numbers in the normal range, some authority decides to lower the bar so the doctors can continue to nag us to "get those numbers down." But how many know about these new tests that scientists have designed to make us work even harder? In case your health care team hasn't told you about them, I thought I should fill you in. D1c.
