Intended Use

The N-Assay TIA Haptoglobin Test Kit is intended to be used for the quantitation of haptoglobin in human serum by immuno-turbidimetric assay. Measurement of haptoglobin may aid in the diagnosis of hemolytic diseases related to the formation of hemoglobin-haptoglobin complexes and certain kidney diseases.

Device Story

The N-Assay TIA Haptoglobin Test Kit is an in vitro diagnostic reagent system used for the quantitative determination of haptoglobin levels in human serum samples. The device utilizes an immuno-turbidimetric assay principle, where haptoglobin in the patient sample reacts with specific antibodies to form immune complexes, resulting in turbidity measured by a clinical chemistry analyzer. The test is performed in a clinical laboratory setting by trained laboratory personnel. The output is a quantitative concentration of haptoglobin, which clinicians use to assess the presence or progression of hemolytic conditions and specific renal pathologies. By providing objective measurement of haptoglobin, the device assists in the clinical evaluation of patients suspected of having hemoglobin-haptoglobin complex-related disorders.

Clinical Evidence

No clinical data provided; device relies on analytical performance characteristics typical of in vitro diagnostic immuno-turbidimetric assays.

Technological Characteristics

Immuno-turbidimetric assay; utilizes antibody-antigen reaction to induce turbidity proportional to haptoglobin concentration; intended for use on automated clinical chemistry analyzers; in vitro diagnostic reagent kit.

Indications for Use

Indicated for the quantitative measurement of haptoglobin in human serum to aid in the diagnosis of hemolytic diseases and certain kidney diseases.

Regulatory Classification

Identification

A haptoglobin immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the haptoglobin (a protein that binds hemoglobin, the oxygen-carrying pigment in red blood cells) in serum. Measurement of haptoglobin may aid in the diagnosis of hemolytic diseases (diseases in which the red blood cells rupture and release hemoglobin) related to the formation of hemoglobin-haptoglobin complexes and certain kidney diseases.

Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 866.9.

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 for devices under the Electronic Product Radiation Control provisions, or other Federal Laws or Regulations.

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).
