General Information About the Test
Test Process and Preparation
It depends on the content of the requested test. For blood sugar (glucose), cholesterol, triglycerides, iron, and some hormone tests (thyroid, insulin), a full overnight fast of at least 8-10 hours is required. If only a hemogram (blood count) is to be performed, it does not matter if you are fasting or full.
Yes. Particularly antibiotics, blood thinners, thyroid medications, and vitamin supplements can alter test results. If you have regular medications that need to be taken on an empty stomach in the morning, be sure to consult your physician about whether to take them before or after giving blood.
While routine urgent tests and complete blood counts are generally resulted within 1-2 hours, detailed hormone, vitamin, or culture tests may take until the next day or a few days to be completed.
