Influence factors of visible components in urine samples by UF-50 urinalysis analyzer

Objective To evaluate the influencing factors of the visible components in the urine samples by UF-50 urinalysis analyzer.Methods 1 200 urine samples taken from inpatients,outpatients and examined people were tested with UF-50 urinalysis analyzer and microscopy.The obtained results were comparatively analyzed.Results UF-50 could test multiparameters quickly and accurately as a foundation of urine test standardization.Due to many complicated influencing factors,the partial false-positive(FP) and false-negative(FN) results existed,so that UF-50 could be an effective screening instrument,but which could not replace microscopy.Conclusion Combined use of UF-50 and microscopy can improve the accuracy in routine urine analysis.
