This assay is designed for use with Beckman's IMMAGE Immunochemistry System. ## Device Story The IMMAGE Immunochemistry System Haptoglobin (HPT) reagent is an in vitro diagnostic assay used on the Beckman IMMAGE Immunochemistry System. It measures haptoglobin concentrations in human serum samples using rate nephelometry. The system automates the reaction process, which occurs at 37°C, utilizing a prediluted antigen excess solution (AGXS) contained within the reagent cartridge. The device is intended for use in clinical laboratory settings by trained laboratory personnel. The system provides quantitative results that assist healthcare providers in assessing patient haptoglobin levels, which are relevant for diagnosing and monitoring various clinical conditions. The automated nature of the IMMAGE system streamlines the assay workflow compared to predicate systems that require off-line preparation of reagents. ## Clinical Evidence Bench testing only. Method comparison study between IMMAGE HPT and predicate (Array Systems) showed a slope of 1.004, intercept of -6.80, and r=0.996. Imprecision studies (n=80 per level) demonstrated %CVs of 1.4% (60.8 mg/dL), 2.5% (136 mg/dL), and 2.8% (322 mg/dL). Stability testing confirmed a 24-month shelf-life, 14-day open container stability, and 14-day calibration stability. ## Technological Characteristics Rate nephelometry assay; reaction temperature 37°C. Reagent includes prediluted antigen excess solution (AGXS). Analytic range 35-350 mg/dL; extended range 5.8-12,600 mg/dL. Designed for use on the IMMAGE Immunochemistry System. ## Regulatory Identification A haptoglobin immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the haptoglobin (a protein that binds hemoglobin, the oxygen-carrying pigment in red blood cells) in serum. Measurement of haptoglobin may aid in the diagnosis of hemolytic diseases (diseases in which the red blood cells rupture and release hemoglobin) related to the formation of hemoglobin-haptoglobin complexes and certain kidney diseases. ## Special Controls *Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 866.9. ## Predicate Devices - Beckman Immunochemistry Systems HPT Haptoglobin Reagent ## Reference Devices - Array® Systems ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
