What time does morning urine usually occur?

The normal morning urine refers to the first urine discharged after getting up in the morning, before breakfast and exercise. Because the urine secreted by the kidneys during sleep enters the bladder storage, the bladder is in a state of fullness when getting up in the morning, and the first urine in the morning belongs to morning urine. It has no direct relationship with the specific time. The first urine in the morning is more accurate as a specimen, and the accuracy of urine test results has a direct impact on the quality of medical care. In order to improve the sensitivity and repeatability of the test, the first urine in the morning has always been used as a specimen for routine urine examination of hospitalized patients. The first morning urine must be tested within two hours, otherwise it will be affected by chemical components, causing red and white cells and casts to show rupture.
