Whether or not morning urine is required for routine urine tests depends on the specific situation. Generally, doctors recommend that patients use morning urine for routine urine tests, and patients often have this habit, thinking that morning urine is more accurate because it is more concentrated and can reflect the condition of urine, such as whether there is an increase in red blood cells or urine protein. If the urine is washed down after drinking a lot of water, it may not be accurate at this time. Because you may have to eat and drink during the day, it will dilute the urine, so in this sense morning urine is relatively good. But as a nephrologist, sometimes we don’t advise patients to choose morning urine. Because the kidney patients will be relieved after resting, they may show relatively lighter, there is quite a lot of protein in the urine, maybe not much protein after resting for one night, and there is a lot of hematuria, maybe not much hematuria. So the nephrologist will tell the patient that there is no need for morning urine for urine routine, as long as they don’t drink a lot of water before the urine routine test, so morning urine and non-morning urine are the same. But some tests must be done with morning urine and must be done with urine after activity, which is a special request from the doctor.
