More Information

Not Found

No
The summary describes a dry film chemistry analyzer and cartridge for measuring calcium concentration. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in medical devices. The performance studies focus on standard analytical chemistry metrics.

No

This device is for in vitro diagnostic use to measure total calcium levels, which aids in diagnosis and treatment, but it does not directly treat a patient or disease.

Yes

Explanation: The "Intended Use / Indications for Use" section explicitly states "For in vitro diagnostic use with the CARESIDE Analyzer™... to aid in diagnosis and treatment of patients with parathyroid disease, a variety of bone diseases, chronic renal disease, and tetany." This directly indicates its role as a diagnostic device.

No

The device description explicitly mentions a "single use disposable in vitro diagnostic test cartridge" and a "film cartridge" containing reagents, indicating a significant hardware component.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use/Indications for Use: Explicitly states "For in vitro diagnostic use". It also describes measuring a substance (total calcium) in biological specimens (whole blood, plasma, serum) to aid in the diagnosis and treatment of various medical conditions. This is the core definition of an IVD.
  • Device Description: Describes a "single use disposable in vitro diagnostic test cartridge".
  • Intended User/Care Setting: While it specifies professional laboratory use and not point-of-care, this still falls under the umbrella of diagnostic testing performed outside of the body.

The information provided clearly indicates that this device is designed and intended for diagnostic testing performed in vitro (outside of the living body) using biological specimens.

Device Description

CARESIDE™ Calcium cartridges are used with the CARESIDE Analyzer™ to measure calcium concentration in heparinized whole blood, heparin plasma or serum specimens. The CARESIDE™ Calcium cartridge, a single use disposable in vitro diagnostic test carridge, delivers a measured volume of serum or plasma to a dry film to initiate the measurement of calcium concentration. The film cartridge (patent pending) contains all reagents necessary to measure calcium concentration.

Each CARESIDE™ Calcium cartridge consists of a calcium-specific multi-layer reagent film mounted in a plastic base with a hinged lid. The user introduces the specimen into the cartridge sample deposition 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°C, and spins the cartridge to move the sample from the sample deposition well into the cartridge channels and chambers. 8.5uL of sample remains 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, and the sample moves through a reagent layer and a detection layer where a dye complex forms in the presence of calcium. The color intensity of the resulting blue dye, as measured by the amount of reflected light at 615 nanometers directly relates to the calcium concentration of the specimen.

Test Reaction Sequence: Ca + Bound-Ca -> Ca +2 Ca-2 + chlorophosphonazo (III) -> Ca-chlorophosphonazo (III)

As the cartridges spin, a photodiode measures reflectance of light emitted by a wavelength-specific light emitting diode (LED) at a fixed time. The analyzer uses the reflectance measurements and the lot-specific standard curve to calculate calcium concentration.

IV. Device Description

CARESIDE™ Calcium cartridges are used with the CARESIDE Analyzer™ to measure calcium concentration in heparinized whole blood, heparin plasma or serum specimens. The CARESIDE™ Calcium cartridge, a single use disposable in vitro diagnostic test carridge, delivers a measured volume of serum or plasma to a dry film to initiate the measurement of calcium concentration. The film cartridge (patent pending) contains all reagents necessary to measure calcium concentration.

Explanation of Device Function A.

Each CARESTDE™ Calcium cartidge consists of a calcium-specific multi-layer reagent film mounted in a plastic base with a hinged lid. The user introduces the specimen into the cartridge sample deposition 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°C, and spins the cartridge to move the sample from the sample deposition well into the cartridge channels and chambers. 8.5uL of sample remains 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, and the sample moves through a reagent layer and a detection layer where a dye complex forms in the presence of calcium. The color intensity of the resulting blue dye, as measured by the amount of reflected light at 615 nanometers directly relates to the calcium concentration of the specimen.

Test Reaction Sequence: Ca + Bound-Ca -> Ca +2 Ca-2 + chlorophosphonazo (III) -> Ca-chlorophosphonazo (III)

As the cartidges spin, a photodiode measures reflectance of light emitted by a wavelength-specific light emitting diode (LED) at a fixed time. The analyzer uses the reflectance measurements and the lot-specific standard curve to calculate calcium concentration.

B. Test Summary

Calcium is an element found in fairly fixed proportions in the mineral phase of the human hard tissues (bone, dentine, and enamel) as well as in dynamic exchange with the intracellular and extracellular tissue fluids. Over 95% of the body calcium store is in the skeleton and tecth. Of the blood calcium, 45-50% is ionized, 40-45% is protein-bound and about 10% is chelated with ligands like citrate, lactate, phosphate and bicarbonates".

Intracellularly, calcium (Ca 1) is a prime inorganic messenger for cell function regulation, Extracellular Cat2 at the cell surface controls secretions from several endocrine glands including the parathyroid and pancreas. Calcium also plays a key role in blood coagulation.

The three main regulators of calcium homeostasis are parathyroid hormone, vitamin D, and calcitonin. Disorders involving these regulators directly impact calcium levels. Calcium level determination in human body fluids is used to measure parathyroid function, to assess vitamin D status; to evaluate calcium metabolism; to diagnose Addison's disease and to investigate malignancies . Increased calcium levels are seen in cases of hyperparathyroidism and malignancy. Reduced levels are commonly seen in cases of hypoalbuminemia
