Device Description

CARESIDE™ ALP cartridges are used with the CARESIDE Analyzer™ to measure alkaline phosphatase activity in anticoagulated whole blood, serum or plasma specimens. The CARESIDE™ ALP 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 alkaline phosphatase activity. The film cartridge (patent pending) contains all reagents necessary to measure alkaline phosphatase activity.

Each CARESIDE™ ALP cartridge consists of an alkaline phosphatase-specific multilayer 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°C, 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 sample is automatically dispensed onto the multi-layer reagent film. The spreading and substrate layer distributes the sample uniformly. Under alkaline pH conditions, ALP catalyzes the conversion of pNPP to pNP. pNP diffuses through the detection layer and into the underlying buffer where pNP converts non-enzymatically to p-nitrophenoxide which has an intense yellow color. The rate of change of color intensity of the resulting yellow dye, as measured by the amount of reflected light at 425 nanometers, directly relates to the alkaline phosphatase activity of the specimen.

Test Reaction Sequence: p-Nitrophenyl Phosphate + H20 ALP ↓ p-Nitrophenol + Phosphoric Acid

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 alkaline phosphatase activity.

B. Test Summary

alkaline phosphatase activity.

Alkaline phosphatase consists of a group of at least five isoenzymes which catalyze the hydrolysis of phosphate mono-esters optimally at an alkaline pH. These isoenzymes vary in their tissue distribution. ALP is found in the kidney, small intestine, osteoblasts, placenta, and liver. Significant elevations of ALP activity in the blood result from hepatobiliary disorders and bone disease associated with increased osteoblastic activity. Modest ALP elevation occurs in pregnancy, congestive heart failure, ulcerative colitis, intra-abdominal infections, Hodgkin's disease and other malignancies. Certain drugs can cause elevation in ALP activity in the blood in vivo.

Dear Dr. Asarch:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
