There are three main ways to test for<unk> . * The first is known as saline microscopy. This is the most commonly used method and requires an endocervical, vaginal, or penile swab specimen for examination under a microscope. The presence of one or multiple trichomonads constitutes a positive result. This method is cheap but has a low sensitivity (60–70%) often due to an inadequate sample, resulting in false negatives. * The second diagnostic method is culture, which has historically been the "gold standard" in infectious disease diagnosis. Trichomonas vaginalis culture tests are relatively cheap; however, sensitivity is still somewhat low (70–89%). * The third method includes the nucleic acid amplification tests (NAATs) which are more sensitive. These tests are more costly than microscopy and culture, and are highly sensitive (80–90%).
