Used in clinical laboratories to monitor precision of immunoassay testing procedures. Provides known concentration samples to verify assay performance. Healthcare providers use results to assess analytical stability and precision of laboratory testing; ensures reliability of patient diagnostic results. ## Clinical Evidence No clinical data; bench testing only. ## Technological Characteristics Liquid-form control; matrix: human serum with added human/non-human constituents. Storage: -10 to -20°C; open vial stability: 14 days at 2-8°C (7 days for folate). ## 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 - Tri-Point Liquimmune Control ([K954322](/device/K954322.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
