High Sensitivity Dengue IgG/IgM Rapid Test with Colloidal Gold Method and 24 Months Shelf Life

Results should be interpreted by qualified medical professionals in combination with clinical symptoms and additional diagnostic tests for final diagnosis and treatment decisions.

The Dengue IgG/IgM Rapid Test is a lateral flow chromatographic immunoassay. The test cassette consists of:

The G band is pre-coated with the antibody for the detection of IgG anti-dengue virus, M band is coated with antibody for the detection of IgM anti-dengue virus, 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-dengue virus if present in the specimen will bind to the dengue conjugates. The immunocomplex is then captured by the reagent coated on the G band, forming a burgundy colored G band, indicating a dengue virus IgG positive test result and suggesting a recent or repeat infection.

IgM anti-dengue virus, if present in the specimen, will bind to the dengue conjugates. The immunocomplex is then captured by the reagent pre-coated on the M band, forming a burgundy colored M band, indicating a dengue virus IgM positive test result and suggesting a fresh infection.

Absence of any test bands (G and M) 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 test bands (G and M). Otherwise, the test result is invalid and the specimen must be retested with another device.

Test specimens as soon as possible after collecting. Store specimens at 2°C-8°C if not tested immediately. Store specimens at 2°C-8°C up to 5 days. The specimens should be frozen at -20°C for longer storage.
