No
The device description details a chemical assay and calculation based on measured values, with no mention of AI or ML technologies.
No
The device is described as an "in vitro diagnostic assay" used to measure hemoglobin A1c, which is used for "monitoring long term glucose control in individuals with diabetes mellitus." It does not provide treatment or directly affect the body's structure or function.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that "The HAIC assay... is an in vitro diagnostic assay".
No
The device is an in vitro diagnostic assay that measures chemical properties of blood samples using a clinical chemistry system, which involves physical components and chemical reactions, 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 an "in vitro diagnostic assay for the quantitative determination of percent hemoglobin Alc (HbAIc) in anticoagulated whole blood." This directly aligns with the definition of an in vitro diagnostic device, which is used to examine specimens derived from the human body to provide information for the diagnosis, prevention, or treatment of disease.
- Device Description: The description details how the assay works by measuring analytes (HbA1c and hemoglobin) in a biological sample (whole blood) outside of the body.
- Performance Studies: The "Summary of Performance Studies" describes method correlation studies using "anticoagulated whole blood samples," further confirming the use of biological specimens in vitro.
The information provided clearly indicates that this device is designed to perform diagnostic tests on samples taken from the human body, which is the core function of an IVD.

Intended Use / Indications for Use
The HA1C assay on the Dimension® clinical chemistry system is an in vitro diagnostic assay for the quantitative determination of percent hemoglobin A1c (HbA1c) in anticoagulated whole blood. Measurements of percent hemoglobin A1c are effective in monitoring long term glucose control in individuals with diabetes mellitus.

Device Description
The Dimension® HA1C assay measures both HbA1c and hemoglobin. The HbA1c measurement is based on a turbidimetric inhibition immunoassay (TINIA) principle, and the measurement of total hemoglobin is based on a modification of the alkaline hematin reaction. Using the values obtained for each of these two analytes (in g/dL), the percentage of the total hemoglobin that is glycated is calculated and reported as %HbA1c. The final %HbA1c result has been standardized to the results obtained in the Diabetes Control and Complications Trial (DCCT).
Pre-treatment to remove the labile fraction is not necessary as only the Amadori rearranged form of HbA1c is detected. All hemoglobin variants that are glycated at the beta-chain N-terminus and have epitopes identical to that of HbA1c, are measured by this assay.

Summary of Performance Studies
Method correlation between the Roche Tina-quant® HBA1C II on Hitachi and Dimension® HA1C methods was evaluated with 136 anticoagulated whole blood samples ranging from 4.9% to 16.7% HbA1c. These samples provided a correlation coefficient of 0.994, a slope of 0.985, and an intercept of 0.3% HbAlc.

§ 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).

Device Name: Dimension® HA1C Assay
Classification Name: Glycosylated Hemoglobin
Predicate Device: Roche Tina-quant® HBA1C II
The Dimension® HA1C assay measures both HbA1c and Device Description: hemoglobin. The HbA1c measurement is based on a turbidimetric inhibition immunoassay (TINIA) principle, and the measurement of total hemoglobin is based on a modification of the alkaline hematin reaction. Using the values obtained for each of these two analytes (in g/dL), the percentage of the total hemoglobin that is glycated is calculated and reported as %HbA1c. The final %HbAlc result has been standardized to the results obtained in the Diabetes Control and Complications Trial (DCCT).
Pre-treatment to remove the labile fraction is not necessary as only the Amadori rearranged form of HbA1c is detected. All hemoglobin variants that are glycated at the beta-chain N-terminus and have epitopes identical to that of HbA lc, are measured by this assay.

Principles of Procedure:
Total Hemoglobin Measurement: A sample of whole blood is added to the first cuvette containing lysing reagent. This reagent lyses the red blood cells and simultaneously converts the released hemoglobin to a derivative that has a characteristic absorbance spectrum. An aliquot of the lysed whole blood is transferred from the first cuvette to a second cuvette where total hemoglobin concentration is measured at 405 nm and 700 nm.
Whole blood + lysing agent --> Released hemoglobin → hemoglobin derivative (measured at 405 nm)
Hemoglobin A1c Measurement: The same aliquot of the lysed whole blood which is transferred from the first cuvette to the second cuvette for the Hb measurement is also used for the measurement of HbA1c. The second cuvette contains an anti-HbA1c antibody in a buffered reagent. Hemoglobin A1c in the sample reacts with anti-HbA1c antibody to form a soluble antigen-antibody complex. A polyhapten reagent containing multiple HbAlc epitopes is then added to this cuvette. The polyhapten reacts with excess (free) anti-HbA1c antibodies to form an insoluble antibody-polyhapten complex. The rate of this reaction is measured turbidimetrically at 340 nm and blanked at 700 nm and is inversely proportional to the concentration of HbA1c in the sample.
hemoglobin A1c + anti-HbA1c antibody → hemoglobin A1c -anti-HbA1c antibody complex
anti-HbA1c antibody (excess) + polyhapten → Ab / polyhapten complex (absorbs at 340 nm)
Intended Use:
The HA1C assay on the Dimension® clinical chemistry system is an in vitro diagnostic assay for the quantitative determination of percent hemoglobin Alc (HbA1c) in anticoagulated whole blood. Measurements of percent hemoglobin A 1 c are effective in monitoring long term glucose control in individuals with diabetes mellitus.
