can you drink water before a fasting blood test

Yes, you can drink water before a fasting blood test. Drinking plain water is actually encouraged because it helps keep you hydrated and makes your veins easier to find for drawing blood. However, you should avoid all other foods and drinks, including coffee, juice, and flavored or sweetened water, during the fasting period, which is usually 8 to 12 hours before the test. Drinking only water does not affect the accuracy of fasting blood test results and is generally allowed. Always follow specific instructions given by your healthcare provider for your particular test.
