Indications for Use
The Clinitek Status®+ Urine Chemistry Analyzer is a portable analyzer. It is designed to read only Siemens Reagent Strips for Urinalysis and Clinitest® hCG tests. This analyzer is intended for the measurement of the following in urine: Albumin, Bilirubin, Blood (Occult), Creatinine, Glucose, Ketone, Leukocytes, Nitrite, pH, Protein, Protein-to-Creatinine Ratio, Albumin-to-Creatinine Ratio, Specific Gravity, Urobilinogen, and human Chorionic Gonadotropin (hCG). These measurements are used to assist diagnosis in the following areas: - Kidney Function - Urinary tract infections - Metabolic disorders (e.g. diabetes mellitus) - Liver Function - Pregnancy Tests performed using the Clinitek Status®+ Analyzer are intended for in vitro diagnostic use only. The Clinitek Status®+ Analyzer is intended for near patient (point-of-care) facilities and centralized laboratory locations.
Device Story
Portable urine chemistry analyzer; reads Siemens Reagent Strips and Clinitest hCG tests. Optical system uses six LEDs, light guide, mirror, lens, and detector to measure reflected light from test strips/cassettes. Microprocessor converts light intensity into clinical results. Features include automatic strip identification, humidity-exposure quality check, user-selectable reporting, and access restrictions. Connect System variant adds barcode entry, QC management, and network connectivity. Used in point-of-care and lab settings by healthcare professionals. Provides objective, automated analysis to assist clinical diagnosis of metabolic, renal, and hepatic conditions, and pregnancy.
Clinical Evidence
Internal performance study evaluated 150 urine specimens comparing the modified device (Clinitek Status+) against the predicate (Clinitek Status). Testing covered urinalysis strips (Multistix 10SG) and hCG cassettes. Results demonstrated percent positive agreement (relative sensitivity) and percent negative agreement (relative specificity) met prescribed requirements. Software verification and validation plans, including risk management, were provided.
Technological Characteristics
Reflectance photometer; six LEDs, light guide, mirror, lens, detector. Portable form factor. Connectivity: optional LIS/HIS via network module. Software: embedded firmware for instrument control and data processing. Calibration: automated via white reflectance bar on test strip table. Sterilization: N/A (in vitro diagnostic instrument).
Indications for Use

the measurement of the following in urine: Albumin, Bilirubin, Blood (Occult), Creatinine, Glucose, Ketone, Leukocytes, Nitrite, pH, Protein, Protein-to-Creatinine Ratio, Albumin-to-Creatinine Ratio, Specific Gravity, Urobilinogen, and human Chorionic Gonadotropin (hCG). There are no changes in reporting ranges as a result of this design improvement.
As with the current analyzer, the Clinitek Status®+ is intended for use in a physician's office or hospital laboratory. Tests performed using the Clinitek Status®+ analyzer are intended for in vitro diagnostic use.
The Clinitek Status®+ analyzer optical system, urinalysis strip analytical method, immunoassay cassette analytical method, and main test steps remain the same as Clinitek Status®. They are not impacted by this design upgrade.
Since the SPlus and SConnect (SPlus instrument with LIS connection) are instrument upgrades only, the reagents used on SPlus and SConnect are the same as the existing reagents used on the Status (predicate instrument). No changes were made to the reagents used with the Clinitek Status, nor were changes made to the instruments optics, reagent handling system, control system, or assay timing.

Color Block Agreement Summaries by analyte / Test condition
- Cases where test device gives same color block response as the predicate device are highlighted in yellow.
- Cases where color block response for the test device and predicate device differ by $\pm 1$ color block are highlighted in blue.
- For each cell in the tabular summary the exact % agreement (test/predicate*100) between the test and predicate device is shown in percent form below as the frequency for each analyte/color block.
% Exact Agreement = sum of specimens where color block response for the test device agrees exactly with the color block response for the predicate device divided by the total number of specimens (x100).
% Within One Block Agreement = (sum of cases where color block response for the test device agrees exactly with the color block response for the predicate device) + (the sum of the cases where the color block response for the test condition are $\pm 1$ color block relative the predicate condition) divided by the total number of specimens (x100).
