People should also see a doctor if they test positive for another STI or a sexual partner tests positive for trichomoniasis or another STI.
People getting tested for trichomoniasis do not need to make any special preparations.
Testing for females usually involves a visual examination of the genitals. A healthcare professional will then use a small brush or swab to take a sample of vaginal discharge and tissue cells, which a laboratory technician will examine under a microscope. Females may also provide a urine sample.
When testing males, a healthcare professional conducts a visual examination of the penis and uses a swab to collect a cell sample from the urethra. Males also need to conduct a urine test.
People with trichomoniasis should follow a full course of antibiotic treatment as prescribed by a healthcare professional.
They should keep in mind that they can become reinfected with trichomoniasis. The
The best way for people to avoid reinfection is to notify sexual partners of their infection diagnosis so that they can also seek antibiotic treatment.
Those who have had trichomoniasis should get retested for the infection 3 months after completing treatment or sooner if symptoms emerge.

The following are common questions and answers about trichomoniasis treatment:
Which antibiotics treat trichomoniasis?
Doctors usually prescribe metronidazole, tinidazole, or secnidazole to treat trichomoniasis.
How long does it take for trichomoniasis to go away after treatment?
Trichomoniasis symptoms usually clear in 7–10 days with treatment.
What will happen if trichomoniasis is left untreated?
Trichomoniasis infections are unlikely to clear on their own. Without treatment, trichomoniasis infections can increase a person’s risk of contracting HIV and herpes and cause problems with pregnancies.
The majority of people with trichomoniasis do not have symptoms. However, the disease can lead to significant health problems without proper treatment. These include a greater risk of getting or transmitting HIV and pregnancy issues.
Treatment with antibiotics is the standard approach to trichomoniasis and is generally effective.
