The description details a chemical reaction and photometric measurement process, with calculations based on a standard curve. There is no mention of AI or ML algorithms for data processing or interpretation.
No.
The device is for in vitro diagnostic use, meaning it aids in diagnosis by measuring amylase levels but does not directly provide therapy or treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states, "For in vitro diagnostic use... to aid in the diagnosis and treatment of patients with disease of the pancreas, salivary gland, and kidney." This directly indicates its role as a diagnostic device.
No
The device description clearly outlines physical components like cartridges, reagent films, plastic bases, lids, and the CARESIDE Analyzer™ which contains hardware like a barcode scanner, heating element, spinning mechanism, photodiode, and LED. This is not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states "For in vitro diagnostic use".
- Specimen Type: It measures analytes (amylase) from biological specimens (whole blood, serum, or plasma).
- Purpose: The measurement is used "to aid in the diagnosis and treatment of patients with disease of the pancreas, salivary gland, and kidney." This is a diagnostic purpose.
- Device Description: The description details a single-use disposable test cartridge containing reagents used to perform a test on a biological sample outside of the body.
- Professional Use: The "Intended User / Care Setting" specifies "For professional laboratory: not for point of care or physician office laboratory use," which is typical for many IVD devices.
All of these points align with the definition of an In Vitro Diagnostic device.

Device Description
CARESIDE™ Amylase cartridges are used with the CARESIDE Analyzer™ to measure amylase activity in whole blood, serum or plasma specimens. The CARESIDE™ Amylase cartridge, a single use disposable in vitro diagnostic test cartridge, delivers a measured volume of serum or plasma to a dry film to initiate the measurement of amylase activity. The film cartridge (patent pending) contains all reagents necessary to measure amylase activity.
Each CARESIDE™ Amylase cartridge consists of an amylase-specific multi-layer reagent film mounted in a plastic base with a hinged lid. The user introduces the specimen into the cartridge Sample Well, closes the lid and inserts the cartridge into the CARESIDE Analyzer™.
Once loaded, the CARESIDE Analyzer™ scans the cartridge barcode, brings the cartridge and the contained specimen to 37℃, and spins the cartridge to move the sample from the Sample Well into the cartridge channels and chambers. 8.5 microliters of sample remains in the metering passage. Any excess sample flows into an overflow well.
The 8.5 microliters of sample is automatically dispensed onto the multi-layer reagent film. The spreading and substrate layer distributes the specimen uniformly. Amylase converts p-nitrophenyl-α-D-maltopentaoside (PNP-Gm) to p-nitrophenyl-oligosaccharides and free oligosaccharides (Gn). The sample mixture diffuses into the underlying detection layer where PNP-Gm is converted by α-glucosidase to generate Gm and p-nitrophenol which converts to a yellow dye. The color intensity of the resulting yellow dye, as measured by the amount of reflected light at 425 nanometers, directly relates to the amylase activity of the specimen.
Test Reaction Sequence:
amylase > PNP-Gm + Gn (m+n=5) PNP-Gs α-glucosidase > PNP + Gm PNP-Gm -
As the cartridges spin. a photodiode measures reflectance of light emitted by a wavelength-specific light emitting diode (LED) over a fixed time period. The analyzer uses the reflectance measurements and the lot-specific standard curve to calculate amylase activity.

III. Substantial Equivalence Claim
- A. General equivalency claim
The ability to monitor analyte-specific biochemical reactions in dry film and other formats is widely recognized and has gained widespread acceptance for use in chemistry assays.
Amylase in vitro diagnostic products, in both dry film and other formats, are already on Amylase products include those that use amyloclastic methods the U.S. market. (measure the disappearance of substrate and include the iodine-starch method), saccharogenic methods (measure the production of sugars such as maltose and glucose), and chromogenic methods (measure a colored product).
B. Specific equivalency claim
This CARESIDE™ Amylase test is substantially equivalent in intended use and clinical performance to the currently marketed Vitros slides for the quantitative measurement of amylase on the Vitros DT 60 II system with the DTSC II module. Both are based on the principle of dry film and are read by reflectance photometry; however, the Vitros method is based upon the conversion of dyed starch to dyed saccharides while the CARESIDE method is based upon the conversion of a synthetic substrate to a colored product.

Each CARESIDE™ Amylase cartridge consists of an amylase-specific multi-layer reagent film mounted in a plastic base with a hinged lid. The user introduces the specimen into the cartridge Sample Well, closes the lid and inserts the cartridge into the CARESIDE Analyzer™.

Any excess sample flows into an overflow well.
The 8.5 microliters of sample is automatically dispensed onto the multi-layer reagent film. The spreading and substrate layer distributes the specimen uniformly. Amylase p-nitrophenyl-α-D-maltopentaoside to p-nitrophenyl-oligosaccharides converts (PNP-Gm) and free oligosaccharides (Gn). The sample mixture diffuses into the underlying detection layer where PNP-Gm is converted by a-glucosidase to generate Gm and p-nitrophenol which converts to a vellow dye. The color intensity of the resulting yellow dye, as measured by the amount of reflected light at 425 nanometers, directly relates to the amylase activity of the specimen.
Test Reaction Sequence:

B. Test Summary
Amylase is an enzyme produced by the pancreas and parotid glands that occurs in blood. Amylase catalyzes the hydrolysis of starch and related polysaccharide to yield maltose and other oligosaccharides. Amylase activity in the blood is elevated in inflammation and hemorrhage of the pancreas and is decreased in pancreatic insufficiency. Amylase measurement is useful in the differential diagnosis of the digestive system. Various other causes of hyperamylasemia include salivary lesions, biliary tract disorders, trauma, neoplastic diseases, ruptured ectopic pregnancy, pulmonary disease, and alcoholic intoxication. Certain drugs can also increase amylase activity in the blood in vivo.
