The Randox Laboratories Limited Calcium Test Kit is an in vitro diagnostic reagent for the quantitative determination of calcium in human serum. This method is based on the interaction of calcium with Arsenazo III to form a coloured complex which can be measured at 650nm. The intensity of the final colour is directly proportional to the calcium concentration. Measurements of calcium are used in the diagnosis and treatment of parathyroid disease, malignant diseases with and without bone involvement, chronic renal failure and a variety of bone diseases.

Dear Dr. Armstrong:
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 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 reqistration, 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 Requlations, 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 requlation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Druq Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in requlatory In addition, FDA may publish further announcements action. 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 requlations.
