Is fasting required for blood tests to assess liver and kidney function?
Disease description:
Recently, I’ve had a poor appetite, so I went to the hospital, where the doctor ordered blood tests. Do I need to fast before having blood tests for liver and kidney function?

Dr. Liu Guoqiang
Required. Begin fasting (no food or drink) after dinner the day before the examination and continue until after the examination is completed to ensure the accuracy of the test results. Avoid consuming overly greasy, spicy, or high-sugar foods for dinner the day before; abstain from alcohol; avoid staying up late; go to bed early and wake up early to ensure adequate sleep; maintain a calm and relaxed mindset. Upon arrival at the hospital, sit quietly for 30 minutes before blood is drawn for testing.
