Before having the test done, it is important to first understand the correct method of collecting urine. If the method is incorrect, the test results may produce errors that can mislead the clinician’s diagnosis. How to collect it? 1, Do not drink a lot of water and coffee, strong tea, etc. before the test. 2.Collection is usually done with a clean and dry container, and disposable urine cups are generally available at medical checkup centers. 3.The urine should be left around 10-30 mL during the examination. 4, collect the middle section of urine. When collecting the middle section of urine, do not collect the urine at the beginning or near the end of urination. Of course, sometimes, for diagnostic purposes, it is specifically ordered to collect the urine at the beginning and the urine at the end. 5. Send the test within the specified time. Collected urine should be sent for examination within half an hour, and no later than one hour. 6, Women should avoid menstruation and clean the vulva before collection to prevent mixing of vaginal secretions. 7.Men with long foreskin should preferably clean the urethra before urine retention and turn up the foreskin when retaining urine.
