can you drink water before fasting labs

Yes, you can and should drink plain water before fasting labs. Drinking water is allowed and even encouraged during the fasting period because it keeps you hydrated and can make it easier to draw blood by plumping your veins. However, you should avoid all other drinks and foods during the fasting period before the lab test, as they can affect the accuracy of the test results. The fasting period typically lasts 8-12 hours, depending on the specific lab test you are having, and only water is permitted during this time. Avoid flavored water, coffee, tea, juice, or any other beverages besides plain water while fasting for labs.
