If erythrocytes, leukocytes, cylinders are increased in a clinical study, the doctor needs confirmation of the data. Since the results appear using microscopy, visual inspection of the mask, it is recommended to conduct a test according to Nechiporenko. With it, a semi-automatic analyzer is used, with the help of which accurate data are obtained, down to each cell.
Normally, testing should give the following data per 1 ml of urine:
• leukocytes up to 2000;
• erythrocytes up to 1000;
• cylinders up to 20 units.
Unlike the previous study, for the Nechiporenko test, not the entire portion of urine is collected, but only the middle part.
