10 x Candida Infection Vaginal Swab Tests

Candida Infection Vaginal Swab Test

A rapid test for the qualitative detection of Candida albicans antigen from vaginal swabs.

INTENDED USE

This test is intended to be used as an aid in the diagnosis of Candida infection. The Candida albicans Rapid Test Cassette (Vaginal Swab) is a rapid chromatographic immunoassay for the qualitative detection of Candida albicans antigens from vaginal swabs.

SUMMARY

The microorganism Candida albicans is an opportunistic pathogenic yeast. It is a common member of the human gut flora. It does not proliferate outside the human body. That is detected in the gastrointestinal tract and mouth in 40-60% of healthy adults. Candida albicans is usually a commensal organism, but can become pathogenic in immunocompromised individuals under a variety of conditions. Albicans is one of the few species of the Candida genus that causes the human infection candidiasis, which results from an overgrowth of the fungus. Candidiasis is for example, often observed in HIV-infected patients. C. albicans is the most common fungal species isolated from biofilms either formed on (permanent) implanted medical devices or on human tissue. C. albicans, together with C. tropicalis, C. parapsilosis and C. glabrata, are responsible for 50–90% of all cases of candidiasis in humans. A mortality rate of 40% has been reported for patients with systemic candidiasis due to C. albicans. Estimates range from 2800 to 11200 deaths caused annually in the USA due to C. albicans causes candidiasis.

PRINCIPLE

The Candida albicans Rapid Test Cassette (Vaginal Swab) is a qualitative, membrane based immunoassay for the detection of Candida albicans antigens. This is done through a visual interpretation of colour development on the internal strip. Anti-Candida albicans antibodies are immobilized on the test region of the membrane. During testing, the specimen reacts with anti-Candida albicans antibodies conjugated to coloured particles impregnated onto the label pad of the test.

The mixture then migrates through the membrane by capillary action, and interacts with reagents on the membrane. If there is sufficient Candida albicans antigens in the specimen, a coloured line will form at the test region of the membrane. The presence of this coloured line indicates a positive result, while its absence indicates a negative result.

The appearance of a coloured line at the control region serves as a procedural control, indicating that proper volume of specimen has been added and membrane wicking has occurred.
