Rubella Virus Ab IgG/IgM Rapid Test
Cat. No.: RH0515R
SPECIMEN: Whole Blood/ Serum/ Plasma
The One Step RV IgG/IgM Test is a rapid chromatographic immunoassay for the qualitative detection of antibodies (IgG and IgM) to Rubella (Virus) in Whole Blood /Serum / Plasma to aid in the diagnosis of RV infection. The test is based on immunochromatography and can give a result within 15 minutes.
The One Step RV IgG/IgM Test is a qualitative membrane strip based immunoassay for the detection of RV antibodies (IgG and IgM) in Whole Blood /Serum / Plasma. The test device consists of: 1) a burgundy colored conjugate pad containing RV recombinant envelope antigens conjugated with Colloid gold (RV 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-RV, T2 band is coated with antibody for the detection of IgG anti-RV, 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-RV, if present in the specimen, will bind to the RV conjugates. The immunocomplex is then captured by the reagent pre-coated on the T2 band, forming a burgundy colored T2 band, indicating a RV IgG positive test result and suggesting a recent or repeat infection. IgM anti-RV if present in the specimen will bind to the RV conjugates. The immunocomplex is then captured by the reagent coated on the T1 band, forming a burgundy colored T1 band, indicating a RV 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.

Specimen Collection and Preparation
Allow the test, specimen, buffer and/or controls to reach room temperature 15-30℃ (59-86℉) prior to testing.
Applying sufficient amount of specimen is essential for a valid test result. If migration (the wetting of membrane) is not observed in the test window after one minute, add one more drop of buffer to the specimen well.
Interpretation of Results
Positive: Control line and at least one test line appear on the membrane. The appearance of T2 test line indicates the presence of RV specific IgG antibodies. The appearance of T1 test line indicates the presence of RV specific IgM antibodies. And if both T1 and T2 line appear, it indicates that the presence of both RV specific IgG and IgM antibodies. The lower the antibody concentration is, the weaker the result line is.
Negative: One colored line appears in the control region(C). No apparent colored line appear in the test line region.
Invalid: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test device. If the problem persists, discontinue using the test kit immediately and contact your local distributor.
