The Randox Laboratories Limited Uric Acid Test Kit is an in vitro diagnostic reagent for the quantitative determination of uric acid in serum. The method used is based on UV detection. Uric acid, which absorbs light at 293nm, is converted by uricase to allantoin, which is nonabsorbing at 293nm. The change in absorbance at 293nm due to the disappearance of uric acid is indirectly proportional to the concentration of uric acid in the sample and is measured using a bichromatic (293, 700nm) end-point technique.
Uric acid measurements are used in the diagnosis and treatment of numerous renal and metabolic disorders including renal failure, gout, leukemia, psoriasis, starvation or other wasting conditions and of patients receiving cytotoxic drugs.
This application sheet has been developed for the Dade Dimension Clinical Chemistry Analyser and must be used by suitably qualified laboratory personnel under appropriate clinical laboratory conditions.

The input provided describes an FDA 510(k) clearance letter and an "Indications For Use" statement for a device named "URIC ACID" from Randox Laboratories Ltd. This document does not contain information about acceptance criteria, study design, or performance metrics in a way that allows for the creation of the requested table and detailed study description about device performance against acceptance criteria.
The document is a regulatory clearance for a diagnostic test kit (an in vitro diagnostic reagent) for the quantitative determination of uric acid in serum. It outlines the method used (UV detection based on uricase converting uric acid to allantoin) and the clinical utility of uric acid measurements.
Therefore, I cannot provide the requested information because the provided text does not contain the details about acceptance criteria or a study that proves the device meets those criteria.
Specifically, the document lacks:
- Acceptance criteria values and reported device performance values: It describes what the device does (measures uric acid) but not how well it performs against specific benchmarks (e.g., accuracy, precision, linearity ranges, acceptable bias).
- Sample size and data provenance for a test set: No figures or origin of data are mentioned.
- Number and qualifications of experts for ground truth: Not applicable for a chemical assay.
- Adjudication method: Not applicable.
- MRMC comparative effectiveness study: Not applicable, as this is a chemical assay, not an AI-assisted diagnostic tool for human readers.
- Standalone performance: While the document implies standalone performance (the kit itself measures uric acid), it doesn't quantify this performance.
- Type of ground truth: For a chemical assay, the "ground truth" would typically be a reference method or known concentration standards, but these are not described.
- Training set sample size: Not applicable to this type of chemical assay.
- How ground truth for the training set was established: Not applicable.
The document is a regulatory approval, not a scientific study report detailing performance metrics.

Dear Dr. Armstrong:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820).

Page 2
This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific information about the application of labeling requirements to your device, or questions on the promotion and advertising of your device, please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 594-3084. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html.
