The IMMAGE Immunochemistry System Immunoglobulin A (IGA) reagent, when used in conjunction with Beckman IMMAGE™ Immunochemistry Systems and Beckman Calibrator 1, is intended for the quantitative determination of human immunoglobulin A by rate nephelometry. The IMMAGE Immunochemistry System Immunoglobulin M (IGM) reagent, when used in conjunction with Beckman IMMAGE™ Immunochemistry Systems and Beckman Calibrator 1, is intended for the quantitative determination of human immunoglobulin M by rate nephelometry. ## Device Story Reagents for IMMAGE Immunochemistry System; perform quantitative determination of human IgG, IgA, and IgM via rate nephelometry. Input: serum or CSF samples; combined with Beckman Calibrator 1. Process: antibody-antigen reaction measured by rate nephelometry at 37°C. Output: quantitative concentration values (mg/dL). Used in clinical laboratory settings; operated by laboratory technicians. Results assist clinicians in evaluating patient immunoglobulin status. ## Clinical Evidence Bench testing only. Method comparison studies (n=247-323 per analyte) against predicate reagents showed high correlation (r=0.971-0.998). Imprecision studies (n=30-80) demonstrated %C.V. ranging from 1.3% to 5.3%. Stability data supports 24-month shelf-life and 14-day open container/calibration stability. ## Technological Characteristics Rate nephelometry; reaction temperature 37°C; antibody-based reagent formulation. System is a clinical chemistry analyzer component. No specific materials or software architecture details provided. ## Regulatory Identification An immunoglobulins A, G, M, D, and E immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the immunoglobulins A, G, M, D, an E (serum antibodies) in serum. Measurement of these immunoglobulins aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents. ## Predicate Devices - Immunochemistry Systems Immunoglobulin G Reagent ([K771603](/device/K771603.md)) - Immunochemistry Systems Immunoglobulin A Reagent ([K771603](/device/K771603.md)) - Immunochemistry Systems Immunoglobulin M Reagent ([K771603](/device/K771603.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
