what can you drink while fasting for blood work

When fasting for blood work, you can drink only plain water. No other drinks like coffee, tea, juice, soda, or alcohol are allowed as they can affect the test results. Drinking water is encouraged to stay hydrated, which also helps make it easier to draw blood. Avoid flavored or carbonated water, and strictly stick to plain water during the fasting period, which usually lasts 8-12 hours before the blood test.
