There is a range of standard medical analyzes performed on the urine: description of appearance and color, glucose, Ph, protein, ketones and others. Very often microscopic urine analyzers are used for this purpose. They give medical men an opportunity to screen for different urine diseases, for example renal one or urinary tract infections. The advantage of these devices is that they also have a function of screening the diseases of other organs which may appear in urine as a result of abnormal metabolites.
The simplest and the most common method of chemical urinalyses is using the utilized commercial disposable test strips. Fresh urine is collected in a dry, clean container and the appropriate strip is run against the rim. The reactions are read visually or automatically with the help of reflection photometer. But if this chemical testing yields normal or negative results, microscopic urine analyzer is used very often. It is a standard practice in many laboratories used to exclude the microscopic exam. A sample of well-mixed urine is centrifuged into a special test tube and first examined under the microscope at both low (to determine the number of casts) and high power (to identify cells, crystals and bacteria).
Traditional manual microscopic techniques have several methodological steps contributing to inaccuracy and imprecision. But modern microscopic urine analyzer is fully-automated and high speed. The most popular one is uf 100 urine analyzer based on flow cytometry. It is designed to bring quality and efficiency to routine urine microscopic examinations. The mentioned microscopic urine analyzer had increased productivity and automated image review with cluster and flow cytometry analysis. It`s throughout output amounts approximately 100 samples per hour. There`s no need to prepare samples thanks to fully-automated workflow. The distinguishing advantage of uf 100 urine analyzer is its sensitivity and unmatched accuracy, a unique combination of forward scatter, fluorescence and impedance technologies, which allow counting urinary formed elements. It classifies urinary particles on the basis of their light scattering and impedance properties counting leukocytes, erythrocytes, bacteria, epithelial cells, casts, etc.
Thus, uf 100 microscopic urine analyzer is offered by Sysmex Corporation. Beside this kind of device the company produces other fully automated analyzers often used in everyday medicine practice. It has become almost impossible to make complicated urine examinations without them. The usefulness of microscopic analysis is outstanding. It is an essential part of renal and urinary tract diseases evaluation.
