After peeing at 5am, peeing again at 7am is not considered morning pee. Morning pee is the first urine that is passed early in the morning after waking up and before eating breakfast and doing exercise. The first pee after waking up at 5 am is morning urine. Morning urine is a common clinical test. The first morning urine will generally be used as a specimen for routine inpatient urinalysis as soon as possible and within 2 hours, and can be used to detect red blood cells, urinary proteins, urinary glucose and other components. The presence of 3 or more red blood cells per field of view under high magnification is called microscopic hematuria, and a urine protein level of >150 mg/d is called positive for urine protein. In addition to morning urine, anterior, middle and posterior segment urine can also be used for testing. Pay attention to maintain good sleep, eat a light diet and avoid strenuous exercise.
