Can I have a urine test done in the afternoon?

A urine test can be done in the afternoon, and random urine samples can be taken at any time for urine testing. Normally, morning urine is taken during a physical examination because the concentration of solute in the morning urine is relatively high and the probability of detecting possible problems is relatively high. However, if the symptoms are severe, such as severe pain in urination, or obvious gross hematuria, a single urine sample is taken at any time for testing, and the positive rate of the test is relatively high. Therefore, urine routine or urine sediment examination is not limited by time. Random urine at any time can be routinely examined. When urine is taken, try to keep midstream urine to eliminate the possibility of external contamination. Midstream urine is relatively clean, unlike urine at the beginning or end of urination, which may be contaminated by external genitals, urethral orifices, etc. Especially when keeping urine culture, be sure to keep middle urine, the possibility of artificial interference in the test results is relatively small.
