Fasting for Renal Panel: What You Need to Know

It's crucial to follow the exact preparation guidelines given by your healthcare provider or the laboratory performing your blood work to obtain reliable test results. If they instruct you to fast before the renal panel testing, be sure to comply for the most accurate result
