Intended Use

This kit is intended for quantifying human IgG subclasses 1, 2, 3, and 4 immunoglobulins in serum on the Olympus™ AU series analyzers. Measurement of these immunoglobulins aids in the diagnosis of abnormal protein metabolism and the body’s lack of ability to resist infectious agents.

Device Story

The Binding Site Human IgG Subclass Kit is an in vitro diagnostic reagent system designed for use on Olympus AU series clinical chemistry analyzers. The device utilizes immunoturbidimetric technology to quantify IgG subclasses (1, 2, 3, and 4) in human serum samples. The assay involves the reaction of specific antibodies with the target IgG subclasses, resulting in turbidity proportional to the concentration of the analyte, which is measured photometrically by the analyzer. The system is intended for use by laboratory professionals in clinical settings to assist in diagnosing protein metabolism disorders and immune deficiencies. The output provides quantitative concentration values, which clinicians use to assess patient immune status and guide therapeutic decisions.

Clinical Evidence

Bench testing only. Precision/reproducibility demonstrated with within-run CVs (1.2-5.5%) and between-run CVs (1.2-5.1%). Linearity confirmed via serial dilutions (r² > 0.99). Method comparison with predicate (n=100) showed strong correlation (r² 0.98-0.9889). Interference testing showed no significant effect from bilirubin, hemoglobin, or chyle.

Technological Characteristics

Turbidimetric assay. Reagents: monospecific sheep IgG antisera (liquid); latex-coated antisera for IgG3/4. Reaction accelerators included. Calibration: 6-point curve. Instrument: Olympus AU series analyzers. Software: standard instrument parameters for turbidimetric analysis.

Indications for Use

Indicated for the quantification of human IgG subclasses 1, 2, 3, and 4 in serum to aid in the diagnosis of abnormal protein metabolism and immune deficiency states in patients.

Regulatory Classification

Identification

An immunoglobulins A, G, M, D, and E immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the immunoglobulins A, G, M, D, an E (serum antibodies) in serum. Measurement of these immunoglobulins aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents.

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 (PMA), 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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. {1}------------------------------------------------ Page 2 – Mr. Jay H. Geller This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to 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), please contact the Office of Compliance at (240) 276-3084.
