The description details a chemical reaction and optical measurement method for determining glucose concentration, with no mention of AI or ML algorithms for data processing or interpretation.
No
The device is described as an in vitro diagnostic (IVD) device used to measure glucose, aiding in diagnosis and treatment monitoring, not providing direct therapy itself.
Yes
This device is specifically stated to be "intended for in vitro diagnostic use" and "aids in the diagnosis and treatment of glucose regulation disorders such as diabetes," which are direct indicators of a diagnostic device.
No
The device description clearly details a physical cartridge with reagents and a mechanical process involving spinning and light measurement, indicating it is a hardware-based in vitro diagnostic device, not software only.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The document explicitly states the device is "intended for in vitro diagnostic use" and is used to "quantitatively measure glucose concentration in whole blood, plasma or serum." It also mentions aiding in the "diagnosis and treatment of glucose regulation disorders such as diabetes." These are all hallmarks of an IVD.
- Device Description: The description details a "single use disposable in vitro diagnostic test cartridge" that performs a chemical reaction on a biological specimen (blood, plasma, or serum) to measure an analyte (glucose). This process is characteristic of an IVD.
- Test Reaction Sequence: The inclusion of a detailed chemical reaction sequence further confirms that the device is performing an in vitro test on a biological sample.
- Intended User / Care Setting: The intended user is "laboratory professionals," which is a common setting for IVD use.

Device Description
CareSide™ Glucose cartridges are used with the Exigent Diagnostics CareSide™ Analyzer to measure glucose concentration in whole blood, plasma or serum specimens. The CareSide™ Glucose cartridge, a single use disposable in vitro diagnostic test cartridge, aids in specimen separation and delivers a measured volume of plasma or serum to a dry film to initiate the measurement of glucose concentration. The film cartridge (patent pending) contains all reagents necessary to measure glucose concentration.
Each Exigent Diagnostics CareSide™ Glucose cartridge consists of a glucose-specific multi-layer reagent film mounted in a plastic base with a hinged lid. The user introduces the whole blood, serum, or plasma specimen into the cartridge sample deposition well, closes the lid and inserts the cartridge into the Exigent Diagnostics CareSide™ Analyzer.
Once loaded, the CareSide™ analyzer scans the cartridge barcode, spins the cartridge to move the sample from the sample deposition well into the cartridge channels and chambers, and brings the cartridge and the contained specimen to 37℃. As the cartridge continues to spin, the blood cells are separated from the plasma/serum and the cells accumulate in the separation well. Approximately ten microliters of plasma (or serum, as applicable) remain in the metering passage. Any excess sample flows into an overflow well.
The plasma (or serum, as applicable) is automatically dispensed onto the multi-layer reagent film. The spreading layer distributes the sample evenly on the film. Protein is removed before the glucose solution diffuses through the reflection layer and reaches the reaction layer. In the reaction layer glucose reacts with oxygen via a glucose oxidasecatalyzed reaction to produce hydrogen peroxide which in turn participates in a peroxidase-catalyzed reaction with the substrate to produce a red dye. The color intensity, as measured by the amount of light reflected at 505 nanometers, is directly related to the specimen glucose concentration.
Test Reaction Sequence:
B-D-glucose + O2 + H2O → slucoseoxidase > D-gluconic acid + H2O2 peroxiduse > Red dye 1,7-dihydroxynaphthalene + 4-aminoantipyrine + 2 H2O2-
As the cartridges spin, photodiodes measure reflectance of light emitted by wavelengthspecific light emitting diodes (LEDs) at a fixed time. The analyzer uses the reflectance measurements and the lot-specific standard curve to calculate glucose concentration.

B. Test Summary
Determination of whole blood, serum or plasma glucose levels is important in the diagnosis and control of hypoglycemia, diabetes, nonketotic hyperglycemia, and various endocrine diseases of the pituitary and adrenal glands. Glucose is often measured as a tolerance test after the administration of doses of glucose or insulin. While clinical diagnoses should not be based upon glucose measurements alone, the following criteria for the diagnosis of diabetes mellitus have been proposed by the American Diabetes Association (ADA Glucose Guidelines Diabetes Care, Volume 20, Number 7, p. 1183-1197, July 1997), including: 126 mg/dL (fasting), 200 mg/mL (non-fasting with symptoms), 200 mg/dL (2-hour oral glucose tolerance).
