CLINICAL DIAGNOSTICS
Yeast Infection (Candidiasis)
Candidiasis is an infection caused by a species of yeast called Candida, usually Candida albicans. This is a common cause of vaginal infections in women. Also, Candida may cause mouth infections in people with reduced immune function, or in patients taking certain antibiotics. Candida can be found in virtually all normal people but causes problems in only a fraction. In recent years, however, several serious categories of candidiasis have become more common, due to overuse of antibiotics, the rise of AIDS, the increase in organ transplantations, and the use of invasive devices (catheters, artificial joints and valves) – all of which increase a patient’s susceptibility to infection.
Most women with vaginal candidiasis experience severe vaginal itching. They also have a discharge that often looks like cottage cheese and has a sweet or bread-like odor. The vulva and vagina can be red, swollen, and painful. Sexual intercourse can also be painful.

Test Information
Organism List:
Atopobium vaginae, BVAB2, Gardnerella vaginalis, Lactobacillus crispatus, Lactobacillus gasseri, Lactobacillus iners, Lactobacillus jensenii, Megasphaera 1, Megasphaera 2, Mobiluncus curtisii, Mobiluncus mulieris, Prevotella bivia.
Clinical Utility:
Retrogen's Bacterial Vaginosis (BV) program utilizes ThermoFisher's patented TaqMan technology, providing accurate diagnostic testing to identify and discriminate among 14 pathogens known to be responsible for bacterial vaginosis. The program only requires a single, non-invasive sample collection, has a very short turnaround time, and provides your referring physician a detailed, comprehensive report that leads to actionable decisions and forward treatment options.
Method:
Retrogen carries out real-time PCR on DNA extracted from vaginal swabs to screen for microorganisms known to be associated with BV. This quantitative approach uses TaqMan chemistry from Life Technologies to detect 16S rRNA gene sequences from pathogenic bacterial species.
