can you drink water before blood tests

Yes, you can drink water before blood tests. In fact, drinking plenty of plain water is recommended because it helps keep you hydrated, which makes it easier for the clinician to find veins and draw blood. Water does not affect the results of blood tests since it is free of nutrients that could interfere with the measurements. However, if you are instructed to fast before a blood test, you should avoid eating or drinking anything except water for typically 8 to 12 hours before the test. Other beverages like juice, coffee, or soda can affect the test results and should be avoided during the fasting period. Always follow specific instructions given by your healthcare provider related to fasting requirements for your particular blood test.
