In order to improve the accuracy of the urine test, women need to pay attention to the following matters: first, pay attention to avoid urine tests during menstruation, because during menstruation may lead to false hematuria, affecting the final test results. Secondly, it is best to take a urine test in the middle of the urine, that is, after some urine has been excreted, and it is best to take the morning urine. Then, after taking the urine, pay attention to the use of clean containers to retain 100-200ml of urine, and must be completed within half an hour for testing. Finally, if the patient needs to do 24-hour protein quantification, it is necessary to retain urine, and attention should be paid to the timely addition of preservatives such as toluene to the retained urine to avoid affecting the test results.
