Hello, Anon! Thank you for writing.
For the benefit of our readers -trichomoniasis is a common sexually transmitted infection caused by a parasite. In women, trichomoniasis can cause a foul-smelling vaginal discharge, genital itching, and painful urination.
Ask your doctor if you and your partner should retest. It is possible to get a false negative. This can sometimes occur when the sample is diluted (from not using first-void urine or from urinating too close to the time you will be tested). And even if the test shows a false negative, it’s still possible to spread the infection. That’s why it’s important to seek treatment, for example, if your partner tests positive for trich, even if you test negative. Or the reverse.
