Answer

Trichomoniasis is thought to be widely underdiagnosed owing to various factors, including a lack of routine testing, [2] the low sensitivity of a commonly used diagnostic technique (wet mount microscopy), [11, 12, 13] and nonspecific symptomatology. Self-diagnosis and self-treatment or diagnosis by practitioners without adequate laboratory testing may also contribute to misdiagnosis. Currently, the Centers for Disease Control and Prevention (CDC) recommends numerous molecular detection methods to diagnose trichomoniasis, including several validated nucleic acid amplification tests (NAATs) and an antigen-detection test.
