Intended Use

The Optilite IgG4 kit is intended for the quantitative in vitro measurement of IgG4 in serum using the Binding Site Optilite analyser. Measurement of this immunoglobulin is an aid in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents. The test result should be used in conjunction with other laboratory and clinical findings.

Device Story

The Optilite IgG4 kit is an in vitro diagnostic reagent system for use on the Optilite analyzer. It utilizes polyclonal monospecific sheep anti-human IgG4 (F(ab)2) fragments coated onto polystyrene latex particles. The device measures IgG4 concentration in serum via a turbidimetric immunoassay. When the sample is mixed with the reagent, insoluble complexes form; the analyzer measures the reduction in transmitted light through the suspension, which is inversely proportional to the IgG4 concentration. The analyzer automatically calculates concentrations using a stored calibration curve. The device is intended for use in clinical laboratory settings by trained personnel. It provides quantitative results that assist clinicians in diagnosing abnormal protein metabolism and immune deficiencies. The system includes automated antigen excess detection to flag potentially falsely low results in samples with very high IgG4 levels.

Clinical Evidence

No clinical trials were performed. Substantial equivalence was established through analytical bench testing, including precision (n=10 samples over 21 days), linearity, interference studies (bilirubin, hemoglobin, triglycerides, and 14 common drugs), and a method comparison study using 567 serum samples (26 normal, 541 clinical) comparing the Optilite IgG4 Kit to the predicate device. Passing-Bablok regression showed y = 0.91x + 8.09 with r = 0.999.

Technological Characteristics

Turbidimetric immunoassay; polyclonal monospecific sheep anti-human IgG4 (F(ab)2) fragments on polystyrene latex particles. Reagents include reaction buffer with 0.099% sodium azide. Operates on the Optilite analyzer. Standardized against ERM-DA470k. Automated antigen excess detection. Shelf life 6 months at 2–8°C; open-vial stability 3 months; on-board stability 30 days.

Indications for Use

Indicated for the quantitative in vitro measurement of IgG4 in human serum to aid in the diagnosis of abnormal protein metabolism and immune deficiency. For prescription use only.

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.
