Urine microscopy

Urine microscopy is an auxiliary examination method used to check if urine is normal. With the rapid development of modern medical testing technology, the automation process of testing has also been developed. As far as the urine analyzer is concerned, its detection method is simple, fast, and has many detection items, and has good repeatability and specimens. The amount is small, so it has become an important part of clinical urine testing, but it must not replace the traditional microscope to detect urine formation (cells, casts, crystals, tumor cells, etc.), and because of urine analysis Instrument detection is completely different from the detection principle under the microscope, and the reporting method is different. It is difficult to find the corresponding relationship between the two. So far, there is no direct accounting method. Therefore, the instrument method is only a screening experiment, urine Microscope testing is still an important part of urine testing. Through this examination, the corresponding symptoms can be judged. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: not fasting Tips: Do not eat after 9:00 pm the day before the test. Drink water. Check the morning after getting up and do not eat or drink water, which is convenient for inspection. Normal value Urine white blood cell microscopy analysis report correspondence between visual field average and qualitative results 0 to 4 (negative), 10 to 20 (+), 21 to 50 (++), >50 (+++), full vision ( ++++)[10]. Clinical significance Abnormal results: Correspondence between the mean field of view and the qualitative results of the white blood cell microscope analysis report 0 to 4 (negative), 10 to 20 (+), 21 to 50 (++), >50 (+++), full Vision (++++) [10]. People in need of examination: patients with urinary system diseases. Precautions Taboo before the test: Do not eat after 9:00 pm the day before the test. Drink water. Check the morning after getting up and do not eat or drink water, which is convenient for inspection. Requirements for inspection: The doctor patiently operates and checks carefully. Inspection process The urine was 10m, centrifuged at 1200~1300r/min for 5 minutes, and the remaining precipitate was 0.2ml. After mixing, about 20μl of the precipitate was absorbed, dropped into the glass slide, covered with a 18mm×18mm cover glass and then examined by microscopy. First observe the whole piece with a low power microscope (10×10), and carefully observe 10 high power fields (HP) with a high power microscope (10×40). Reporting method: ×× cells/HP. Not suitable for the crowd Inappropriate people: Generally, there is no suitable for the crowd. Adverse reactions and risks No obvious complications and harms.
