Intended Use

The N-Assay TIA Alpha-1-Acid Glycoprotein Test Kit is intended for the quantification of human alpha-1-acid glycoprotein in human serum by immunoturbidimetric assay. Measurement of alpha 1-acid glycoprotein may aid in the diagnosis of collagen (connective tissue) disorders, tuberculosis, infections, extensive malignancy and diabetes.

Device Story

In vitro diagnostic test kit for quantification of human alpha-1-acid glycoprotein in serum samples. Utilizes immunoturbidimetric assay principle; turbidity measured to determine analyte concentration. Used in clinical laboratory settings by trained laboratory personnel. Output provides quantitative concentration values to assist clinicians in diagnosing inflammatory, infectious, or malignant conditions. Benefits patient by facilitating timely diagnosis and monitoring of specified disease states.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Immunoturbidimetric assay kit for serum analysis. Reagent-based chemistry; optical measurement of turbidity. Class I device.

Indications for Use

Indicated for the quantification of human alpha-1-acid glycoprotein in human serum to aid in the diagnosis of collagen disorders, tuberculosis, infections, extensive malignancy, and diabetes.

Regulatory Classification

Identification

An alpha-1-glycoproteins immunological test system is a device that consists of the reagents used to measure by immunochemical techniques alpha-1-glycoproteins (a group of plasma proteins found in the alpha-1 group when subjected to electrophoresis) in serum and other body fluids. Measurement of specific alpha-1-glycoproteins may aid in the diagnosis of collagen (connective tissue) disorders, tuberculosis, infections, extensive malignancy, and diabetes.

Dear Ms. Rees:

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 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 requirement, 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

Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization. To determine if it does, you should contact the Centers for Disease Control and Prevention (CDC) at [phone].

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for *in vitro* diagnostic devices), please contact the Office of Compliance at [phone]. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
