SPECIMEN: Whole Blood/ Serum/ Plasma

INTENDED USE

The One Step TOXO IgG/IgM Test is a rapid chromatographic immunoassay for the qualitative detection of antibodies (IgG and IgM) to Toxoplasma gondii in Whole Blood /Serum / Plasma to aid in the diagnosis of TOXO infection. Toxoplasma gondii is an obligate intracellular protozoan parasite with a worldwide distribution. Serological data indicates that approximately 30% of the population of most industrialized nations is chronically infected with the organism. A variety of serologic tests for antibodies to Toxoplasma gondii have been used as an aid in diagnosis of acute infection and to assess previous exposure to the organism. These tests are the Sabin-Feldman dye test, direct agglutination, indirect hemagglutination, latex agglutination, indirect immunofluorescence, and ELISA. Recently, lateral flow chromatographic immunoassay, such as The Toxo IgM/IgG Rapid Test (Whole Blood/Serum/Plasma) was introduced into the clinic for the serodiagnosis of Toxoplasma gondii infection. One step TOXO IgG/IgM Test is a simple, visual qualitative test that detects TOXO antibodies in human Whole Blood/serum/plasma. The test is based on immunochromatography and can give a result within 15 minutes.

PRINCIPLE

The One Step TOXO IgG/IgM Test is a qualitative membrane strip based immunoassay for the detection of TOXO antibodies (IgG and IgM) in Whole Blood /Serum / Plasma. The test device consists of: 1) a burgundy colored conjugate pad containing TOXO recombinant envelope antigens conjugated with Colloid gold (TOXO conjugates) and rabbit IgG-gold conjugates,2) a nitrocellulose membrane strip containing two test bands (T1 and T2 bands) and a control band (C band). The T1 band is pre-coated with the antibody for the detection of IgM anti-TOXO, T2 band is coated with antibody for the detection of IgG anti-TOXO, and the C band is pre-coated with goat anti rabbit IgG. When an adequate volume of test specimen is dispensed into the sample well of the test cassette, the specimen migrates by capillary action across the cassette. IgG anti-TOXO, if present in the specimen, will bind to the TOXO conjugates. The immunocomplex is then captured by the reagent pre-coated on the T2 band, forming a burgundy colored T2 band, indicating a TOXO IgG positive test result and suggesting a recent or repeat infection. IgM anti-TOXO if present in the specimen will bind to the TOXO conjugates. The immunocomplex is then captured by the reagent coated on the T1 band, forming a burgundy colored T1 band, indicating a TOXO IgM positive test result and suggesting a fresh infection. Absence of any T bands (T1 and T2) suggests a negative result. The test contains an internal control (C band) which should exhibit a burgundy colored band of the immunocomplex of goat anti rabbit IgG/rabbit IgG-gold conjugate regardless of the color development on any of the T bands. Otherwise, the test result is invalid and the specimen must be retested with another device.
