How long should you start drinking water before a UA?

To prepare for a urine analysis (UA), it's generally recommended to start hydrating at least a few hours before the test. Drinking water about 1-2 hours prior can help ensure that you are adequately hydrated without overly diluting your urine. However, excessive water intake immediately before the test can lead to inaccurate results, so moderation is key. Always follow any specific instructions provided by your healthcare provider.
