Urine formed element candidate reference measuring method based on quantitative counting method principle

The invention relates to a urine formed element candidate reference measuring method based on a quantitative counting method principle. The method comprises the steps that an instrument is selected; urine samples are collected; the urine samples are divided into three sets for counting, and six specimens are obtained for counting; all the urine sample sets are directly detected without being processed through centrifugation; all the urine sample sets are filled in counting pools of disposable counting boards through a calibrated pipettor; standing is performed for 3 minutes after the counting pools of the counting boards are filled with all the urine sample sets, and full morphology and distribution of formed elements in the counting pools are observed by adopting a low power lens of a microscope; by adopting a high power lens of the microscope, the cell constituents are observed and identified, and the number is calculated; the variable coefficient CV of epithelial cells (EC) is smaller than 14%; the variable coefficient CV of red blood cells (RBC) and white blood cells (WBC) is smaller than 7%; the standard uncertainty is synthesized according to the expanded uncertainty of counting of the urine red blood cells, the white blood cells and the epithelial cells. According to the method, the accuracy and reliability of inspection results are guaranteed, and then mutual communication and recognition of the urine inspection results can be promoted.
