Synthetic detecting method for urine

Abstract

A urine comprehensive test method is provided, which is to combine three urine test methods comprising the urine dipsticks analysis, the flow cytometer urine sediment analysis and the microscopic examination on urine sediment. First, test the urine by the urine dipsticks analyzer and the flow cytometer urine sediment analyzer; second, judge if the microscopic examination under the doctor's advice is needed if the urine is tested to be the patient suffered from renal diseases; third, make a smart judgment to the test result of the flow cytometer urine sediment analysis; finally, make comprehensive analysis to the test result of the urine dipsticks analysis and the flow cytometer urine sediment analysis to see if the microscopic examination is needed on he urine sediment. The method can fast and correctly determine the partial important samples needed for manual urine sediment check by the microscopic examination, which saves the human and material resources with reliable test result, and obviously improve the efficiency of the urine test without any influence on the test accuracy.

Description

technical field [0001] The invention relates to the field of medical detection, and relates to a urine comprehensive detection method. Background technique [0002] Urinalysis is the most commonly used and irreplaceable test item for assessing health and disease status, especially for kidney disease. At present, the main methods used in urine testing are: urine dry chemical analysis, uroflow sediment analysis and urine sediment microscopy. [0003] The principle of urine dry chemical analysis is to detect the components in urine by detecting enzymes or chemicals in urine and / or urine cells. The module of the special reagent changes color, the color depth is proportional to the concentration of the corresponding substance in the urine. [0004] Urine flow sediment analysis method, after the cells in the urine are stained with fluorescent pigments, under the action of the sheath fluid, a single, columnar cell flow is formed, which quickly passes through the laser detection a...

AI Technical Summary

Problems solved by technology

[0007] Although urine dry chemical analysis method is simple, fast and convenient for automatic analysis, due to methodological limitations, its false positive and false negative rates are high, and due to the large difference in product quality of dry chemical test strips, there is still a lack of Strict specification, can only be used for coarse screen test

[0008] Uroflow sediment analysis cannot completely eliminate the interference of various formed components in urine on cell counts, and has a low ability to distinguish cells, casts, and crystals, and cannot completely replace microscopy

[0009] Microscopic examination of urine sediment is a recognized standard in the academic community, but this method relies on manual detection, which is slow, time-consuming, and susceptible to subjective factors

[0010] Although experts and scholars have repeatedly emphasized that there are certain methodological limitations in urine dry chemical analysis, clinical application needs to be combined with urine sediment microscopy for comprehensive judgment, but due to the workload, scale, facilities and Due to differences in factors such as technical strength, in fact, there are still many laboratories that only use urine dry chemical analysis to directly report
