Firstly should be clear : urine analyzer test is only a screening test, firmly opposed some units use urine after chemical analyzer will no longer be microscopic urine dreg wrong tendency. Some units will no longer quote urine color, transparency and general properties check, this is wrong. Many institutions will thermal papers report directly to stick on the list in practice is wrong, for thermal papers report on the handwriting encounter heat or a few years will resolve, not as file save.
1 Operators must be carefully before taking up their jobs to reading the instruments instruction and know the determination of instrument principle, operating rules, calibration methods and the instrument maintenance requirements.
2 Must understand the film with the test of reaction mechanism, the points for attention and the drugs can appear abnormal of interference and reference range. Part of the instrument on though it automatic correction, but still should insist every day will instrument with the correction of random with calibration, measured results and correction marked with the result is consistent, only to prove the device is the same in normal operation condition. Must do record carefully.
3 Use "normal" and "abnormal" two concentration quality content for testing every day. If "normal" that control the results into abnormalities, or "abnormal" thing to control the normal to failure are results, should stop detection of patients with specimens, looking for reason. If a piece of quality content in a target value degree is obtai within a level, still as out of control to punish. Above content test results shall control the detailed record.
4 Urine specimen must be fresh, and according to requirements enrol your biometrics. From the eduction to testing should be done in 2 hours, otherwise, it will affect urine chemical components and visible part, such as not timely inspection or analysis.And it should sotre under 4 ℃ , but the longest time of cold storage must not exceed 6 hours. Sometimes some cold storage which will impact the crystallization. From out of the refrigerator urine sample should be placed in a certain amount of time at room temperature, make urine specimen to room temperature constant temperature flat after mixing outright, and then testing samples.
5 Urine test belt should be according to the manufacturer's recommended preservation conditions and use in the effective period. Should not try to take on under the direct light or exposed to radiation in damp environment. Once the required amount of try take only with, and shall be immediately put the cap. Try extra with may not be returned to the original container, more should not be each bottle of merger with try. Operation: do not touch the try take attention reaction monitoring of film.
6 To pay attention to try drugs with determination of interference. Especially vitamin C can make the urine, bilirubin and uric bravery former is false negative. To avoid the effect of the vitamin C, can choose the fight vitamin C with or try with the vitamin C film piece of color try belt. The current domestic urine test have not agreed with the quality standards, so that it can cause the result differences, therefore do not easily replace different manufacturers try belt.
7 To pay attention to urine analyzer with manual measuring results of chemical method of the differences. For example the urine test with determination is of albumin, but not sensitive to globulin; With the sensitivity of urine glucose oxidase determination than class's method is high, but high concentration measure only 3 +; Uric bilirubin try take the result is better than harrison craft law sensitivity low; Check whether can only detect urine white blood cells called, but not with lymphocytes reaction, etc, please refer to the related reports in the literature.
