NO. 420,421,422,425,426) (K965171) _Bio-Rad · JJY · Jan 13, 1997 · Clinical Chemistry · SESE_ **Canonical URL:** https://fda.innolitics.com/submissions/CH/subpart-b%E2%80%94clinical-chemistry-test-systems/JJY/K965171 ## Device Facts - **Applicant:** Bio-Rad - **Product Code:** [JJY](/submissions/CH/subpart-b%E2%80%94clinical-chemistry-test-systems/JJY.md) - **Decision Date:** Jan 13, 1997 - **Decision:** SESE - **Submission Type:** Traditional - **Regulation:** 21 CFR 862.1660 - **Device Class:** Class 1 - **Review Panel:** Clinical Chemistry ## Indications for Use Liquichek Urinalysis Control is intended for use as an assayed quality control urine to monitor the precision of laboratory dipstick and microscopic testing procedures for the analytes listed in the package insert. ## Device Story Liquichek Urinalysis Control is a liquid-form quality control product derived from human urine, supplemented with human erythrocytes, leukocytes, non-human constituents, and pure chemicals. Used in clinical laboratory settings by technicians to monitor the precision of urinalysis dipstick and microscopic testing procedures. The control provides a known reference point to verify the performance of analytical methods. By ensuring the accuracy and precision of these tests, the device assists healthcare providers in maintaining reliable diagnostic results for patient urinalysis, ultimately supporting clinical decision-making regarding patient health status. ## Clinical Evidence Bench testing only. No clinical data provided. ## Technological Characteristics Liquid-form control matrix derived from human urine; contains human erythrocytes, leukocytes, and chemical constituents. Level 2 contains 0.1% sodium azide preservative. Storage at 2-8°C. Open vial stability: 2-8°C for 30 days/10 immersions or 18-25°C for 7 days/10 immersions. ## Regulatory Identification A quality control material (assayed and unassayed) for clinical chemistry is a device intended for medical purposes for use in a test system to estimate test precision and to detect systematic analytical deviations that may arise from reagent or analytical instrument variation. A quality control material (assayed and unassayed) may be used for proficiency testing in interlaboratory surveys. This generic type of device includes controls (assayed and unassayed) for blood gases, electrolytes, enzymes, multianalytes (all kinds), single (specified) analytes, or urinalysis controls. ## Predicate Devices - Liquid Urine Control ([K890577](/device/K890577.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
