No, Trichomonas (aka Trich) is not new, but symptoms can be vague or non existent in up to half of those infected. To compound the problem, the test used to confirm a diagnosis produces a false negative (negative result even though infection is present) around 40% of the time. However, Trich is common and worldwide the incidence is double that of Chlamydia and Gonorrhea combined.
According to the CDC, women may expereince symptoms that include vaginal discharge with a strong odor that is frothy and/or yellow-green. The infection can also cause pain during intercourse or urination. Men almost never have symptoms, but some may temporarily have an irritation inside the penis, mild discharge, or slight burning after urination or ejaculation.
The good news that the FDA has recently approved the APTIMA assay and one study showed that it detected 100% of Trichomonas infections. We will definitely stay on top of this and add it to our test menu as soon it becomes available.
