The description details a standard immunoturbidimetric assay and colorimetric measurement with calculations performed by the existing laboratory systems (AEROSET® and ARCHITECT® c8000™). There is no mention of AI or ML in the device description, intended use, or performance studies.
No
The device is an in vitro diagnostic assay used for monitoring blood glucose control, not for direct treatment or therapy.
No
The "Intended Use / Indications for Use" states, "The MULTIGENT™ Hb A1c assay is not intended for use in diagnosing diabetes mellitus."
No
The device description clearly states it consists of reagents, calibrators, and controls, which are physical components used in a laboratory setting. While it utilizes software on the AEROSET® and ARCHITECT® systems for calculation, the core device is not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the assay is used for the "quantitative in vitro measurement of percent Hb Alc (hemoglobin fraction) in human whole blood". The term "in vitro" is a key indicator of an IVD. It also mentions that the calibrators and controls are "intended for in vitro diagnostic use".
- Device Description: The description details the components (reagents, calibrators, controls) and how they are used to measure Hb A1c in a laboratory setting, which is consistent with an IVD.
- Clinical Context: The assay is intended to "aid in the monitoring of long-term blood glucose control and compliance in individuals with diabetes mellitus," indicating a clinical diagnostic purpose.
- Performance Studies: The inclusion of performance studies like Linearity, Specificity, Precision, and Method Comparison are standard for demonstrating the analytical performance of an IVD.
- Predicate Device: The mention of a "Predicate Device" (K011434; Tosoh Medics Inc., G7 Automated HPLC Analyzer: HbA1c Variant Analysis Mode) is a regulatory requirement for demonstrating substantial equivalence to a legally marketed IVD.
All of these factors strongly indicate that the MULTIGENT™ Hb A1c assay is an In Vitro Diagnostic device.

Device Description
The Device consists of the MULTIGENT™ Hemoglobin A 1 c Reagents, MULTIGENT™ Hemoglobin Alc Calibrators , and MULTIGENT™ Hemoglobin A 1 c Controls, intended for use on AEROSET® System and ARCHITECT® c8000™ System for determination of stable % HbAlc.
The assay consists of two separate concentration measurements, the stable form of glycated hemoglobin (Hb A 1 c) and the total hemoglobin (THb), which are used only to determine the percent Hb Alc. and must not be used individually for diagnostic purposes.
The whole blood specimen is pre-treated to lyse the erythrocytes. The hemoglobin is degraded by the proteolytic enzyme, pepsin, to form a hemolysate. Both the THb and the Hb A1c concentrations are determined from the same hemolysate.
The concentration of total hemoglobin is determined colorimetrically using a wavelength of 604 mm. The sample's measured absorbance is compared to a two-point calibration curve for total hemoglobin.
The concentration of stable Hb Alc is measured immunoturbidimetrically using a microparticle agglutination inhibition method. The Hb A1c antibody reagent (R1) contains specific anti-Hb A 1c mouse monoclonal antibodies coupled to microparticles. The Hb A1c agglutinator reagent (R2) contains several copies of the immunoreactive portion of Hb A1c (hapten), covalently bound to a polymer.
In the absence of Hb Alc in the sample, the hapten in the R2 reagent binds with the antibodycoated microparticles in the R1 antibody reagent and results in an increase in the rate of agglutination and results in an increase in measured absorbance. In the presence of HD A Ic in the sample, the Hb Alc competes with the hapten in the R2 reagent for binding sites on the antibody-coated microparticles in the R1 antibody reagent and will slow the rate of agglutination as it competes with the Hb Alc agglutinator for antibody binding sites.
The increase in concentration of Hb Alc in the sample is inversely proportional to the rate of agglutination and the measured absorbance. The absorbance is measured using a wavelength of 700 nm. The measured absorbance of the sample is compared to the measured absorbance of known Hb Alc concentrations (g/dL) of a six-level calibration curve, and the concentration of the sample is interpolated. The percent Hb A1c is the Hb A1c /THb ratio, calculated automatically by the AEROSET® System and ARCHITECT® c8000™ System, using a conversion factor to correlate the result with an NGSP-certified method.
The calibrators are supplied in liquid form and are ready to use without pretreatment. The controls are supplied in lyophilized form and are to be reconstituted with the supplied reconstitution fluid.

§ 864.7470 Glycosylated hemoglobin assay.
(a)
Identification. A glycosylated hemoglobin assay is a device used to measure the glycosylated hemoglobins (A1a , A1b , and A1c ) in a patient's blood by a column chromatographic procedure. Measurement of glycosylated hemoglobin is used to assess the level of control of a patient's diabetes and to determine the proper insulin dosage for a patient. Elevated levels of glycosylated hemoglobin indicate uncontrolled diabetes in a patient.(b)
Classification. Class II (performance standards).

5. DESCRIPTION OF DEVICE:
The Device consists of the MULTIGENT™ Hemoglobin A 1 c Reagents, MULTIGENT™ Hemoglobin Alc Calibrators , and MULTIGENT™ Hemoglobin A 1 c Controls, intended for use on AEROSET® System and ARCHITECT® c8000™ System for determination of stable % HbAlc.

6. INTENDED USE:
The MULTIGENT™ Hb A1c assay is used in clinical laboratories for the quantitative in vitro measurement of percent Hb Alc (hemoglobin fraction) in human whole blood on the AEROSET® System and ARCHITECT® c8000™ System. The Hb A 1 c assay is intended to aid in the monitoring of long-term blood glucose control and compliance in individuals with diabetes mellitus. The MULTIGENT™ Hb A1c assay is not intended for use in diagnosing diabetes mellitus.
The MULTIGENT™ Hb A1c Calibrators are intended for in vitro diagnostic use with the AEROSET® System and the ARCHITECT® c8000™ System for the calibration of the assays in the MULTIGENTTM Hb A1c Reagent Kit.
The MULTIGENT™ Hb Alc Controls are intended for in vitro diagnostic use with the AEROSET® System and the ARCHITECT® c8000™ System for quality control of the assays in the MULTIGENTTM Hb A1c Reagent Kit.
7. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS:
The MULTIGENT™ Hemoglobin A1c system for measuring % Hb A1c is based on an immunoturbidimetrically microparticle agglutination inhibition method that is specific for stable Hb Alc and is used in conjunction with a colorimetric method to determine the Total Hemoglobin.
The Predicate device, Tosoh Medics Inc., G7 Automated HPLC Analyzer: Hb A1c Vanant Analysis Mode, uses an automated High Performance Liquid Chromatography (HPLC) system, a cation exchange column and gradient elution buffers which separates the stable Hb A1c from other hemoglobin components
Although the MULTIGENT™ Hemoglobin A1c system has technological differences from the predicate device, the intended use are similar and the results from performance characteristics data from non-clinical studies supports a claim of substantial equivalence to the predicate device.
The performance data is summarized below.
