Views: 401

A new assay could provide an effective way of identifying Trichamonos vaginalis, a common sexually transmitted infection, a study carried out at Rhode Island Hospital in the US has revealed. Researchers compared the new test, the Aptima Assay, with the Affirm assay, the only US Food and Drug Administration (FDA) approved diagnostic test for identifying pathogens associated with bacterial vaginitis. The study evaluated 766 women, and the results showed that the Affirm assay produced both false positive and false negative results. However, the Aptima assay detected 36% more infected women, and yielded a sensitivity of 100% with no false positives. The Aptima assay uses a special type of amplification to detect Trichamonos vaginalis. The Aptima assay has been submitted to the FDA for approval.
