Device Description
The Sysmex® UF-5000 Fully Automated Urine Particle Analyzer is an automated urine particle analyzer that is used in the clinical laboratory to analyze formed elements in urine samples quantitatively and flag for the presence of particles/cells in the sample. It provides screening of abnormal samples, as well as automation and better efficiency in the laboratory. The analyzer reports analysis results on five enumerated parameters in urine: RBC (Red Blood Cells), WBC (White Blood Cells), EC (Epithelial Cells), CAST and BACT (Bacteria). It also reports flagging information on the following parameters in urine: Pathologic Cast; Crystal; Sperm; Yeast like cell; and Mucus. This flagging information alerts the operator for the need of further testing and/or review.
The Sysmex® UF-5000 Fully Automated Urine Particle Analyzer is a dedicated system for the analysis of microscopic formed elements in urine and uses a Microsoft® Windows Operating System. The analyzer consists of the following units: (1) Main Unit which aspirates, dilutes, mixes and analyzes urine samples and processes data from the main unit and provides the operator interface with the system; (2) Sampler Unit which supplies samples to the main unit automatically; and (3) Pneumatic Unit which supplies pressure and vacuum to the main unit.
The analyzer uses five reagents-UF-CELLSHEATH (sheath reagent), UF-CELLPACK CR and UF-CELLPACK SF (diluents) and UF-Fluorocell CR and UF-Fluorocell SF (both stains). The quality control material is UF-CONTROL.

- Linearity
- Precision (Repeatability and Reproducibility) ●
- Carryover ●
- Specimen Stability ●
- Reference Interval ●
- Method Comparison
Evaluation of the performance characteristics establishes that the performance, functionality, and reliability of the Sysmex® UF-5000 Fully Automated Urine Particle Analyzer are substantially equivalent to the predicate device.

Identification. An automated cell counter is a fully-automated or semi-automated device used to count red blood cells, white blood cells, or blood platelets using a sample of the patient's peripheral blood (blood circulating in one of the body's extremities, such as the arm). These devices may also measure hemoglobin or hematocrit and may also calculate or measure one or more of the red cell indices (the erythrocyte mean corpuscular volume, the mean corpuscular hemoglobin, or the mean corpuscular hemoglobin concentration). These devices may use either an electronic particle counting method or an optical counting method.(b)
