How should I prepare for a blood test?

Preparation for a blood test can vary depending on the type of test being conducted. Generally, patients may be advised to fast for 8-12 hours before a blood draw, especially if the test involves blood glucose or lipid levels. It’s important to continue drinking water and take medications as prescribed unless directed otherwise by your doctor. Wearing loose-fitting clothing with sleeves that can easily be rolled up is also recommended for accessibility to the venipuncture site.
