Urine testing is the most basic way to diagnose kidney disease, but test results can be affected by the quality of urine specimens taken.
1.Collect morning urine.
As the name suggests, morning urine is the first urine that is expelled from the bladder after waking up in the morning.
People do not eat and drink during sleep, the components in morning urine will not be affected by eating, drinking, exercising, etc., the physiological state is the most stable, and a variety of components that the kidneys excrete into the urine are stored in the bladder and concentrated, so morning urine can improve the positive detection rate of urine.
2.Ensure that the urine specimen is clean.
Errors in test results due to contamination are very common. When collecting urine, be sure to ensure that it is clean.
When women collect urine, they should avoid the menstrual period and clean it before retaining urine**; Men should clean their heads first and then take urine in the middle to prevent secretions from mixing.
3.Urine is collected in the midsection.
Keeping the middle urine means not letting the first and last sections of urination be left behind, because the anterior and posterior urinary sections are easily contaminated and affect the test results. This is done by quickly counting "1,2,3" at the beginning of urination, and then taking no less than 10 ml of urine with a urine cup.
4.Timely inspection.
Long-term placement of urine specimens will be contaminated by bacteria, and the cells in the urine will also be affected by various factors, resulting in a decrease in the accuracy of the test, so the urine specimen should be sent for testing within 2 hours after retention.
