Anyone who thinks they might have trichomoniasis should get a test for this condition. Without treatment, trichomoniasis can increase the risk of a person contracting HIV.
Trichomoniasis, which people often refer to as “trich,” can also increase the risk of pregnancy complications, such as premature labor or low birth weight.
This article discusses what trichomoniasis is and how tests for the infection work. It also lists some of the tests available to purchase online and explains when to speak with a doctor.
Causes of trichomoniasis
The cause of trichomoniasis is a parasite that
- having vaginal sex
- sharing sex toys
- touching the genitals with the hands after touching fluid that contains the infection
- having vulva-to-vulva contact
The majority of people with trichomoniasis do not have symptoms. For those who do, it can take
People who test positive for trichomoniasis, and their sexual partners, should receive treatment for the condition.
If a person has trichomoniasis or is receiving treatment for it, they can help prevent transmission by avoiding sexual activity until after they have finished their course of antibiotics. It is also important for a person’s partners to undergo testing and treatment to prevent reinfection.
Possible signs of trichomoniasis
A trichomoniasis test requires a person to collect a sample of their urine or vaginal secretions.
Common methods for analyzing samples in a trichomoniasis test
- Nucleic acid amplification test (NAAT): This test has over 90% sensitivity in detecting trichomoniasis.
- Wet prep: Potentially due to its cost, doctors often use this test process, though it is not the most sensitive. This method requires analysts to use microscopes to look for parasites in samples.
- Culture: Growing cultures from samples may yield high quality test results, but it can take up to 7 days to get results.
A trichomoniasis test can be positive, negative, or unclear. If the results are positive and a person has an infection, a healthcare professional can treat the infection.
Whether people undergo testing at a clinic or take an at-home test, they should discuss the test results with a licensed healthcare professional.
A follow-up test may be necessary if the results are unclear. Even if the test comes back negative, the

In addition, trichomoniasis
- pregnancy complications, including preterm labor, premature rupture of membranes, and lower birth weight
- inflamed prostate

Individuals should also discuss STI risks with new partners before engaging in sexual activity. People and their partners may wish to receive STI testing before having sex to ensure they do not have any STIs.
People who have symptoms of trichomoniasis, such as genital irritation, itching, unusual discharge, or discomfort, should consider asking a doctor about getting a trichomoniasis test.
However, because this STI often does not produce symptoms, people should also speak with a doctor or get a test if they:
- received a diagnosis of a different STI
- have a sexual partner who has tested positive for trichomoniasis or another STI
- had sex without a condom or other barrier method with someone without knowing their sexual history
A person should follow up with their doctor after a positive test result. Their doctor can prescribe the necessary medication to treat the infection.
Questions to ask a doctor
A person may wish to ask the following questions when receiving testing or treatment for STIs:
- How long does it take to receive the test results?
- Which STIs should I receive testing for?
- How often should I receive testing for STIs?
- What are the potential complications of STIs?
- What is the treatment for the infection?
- Can medication cure the infection?
- How long do I have to take the medication?
- When can I have sex after testing positive for an STI?
- Are there any ways to reduce the risk of transmitting or contracting an STI?
Anyone who suspects they have been exposed to trichomoniasis should receive testing as soon as possible. If a person is using an at-home test, they should follow all the directions from the company to ensure a more accurate result.
While awaiting test results, people should avoid having sex with another person to reduce the risk of transmitting trichomoniasis.
The following are the answers to some common questions about trichomoniasis testing.
Are at-home trichomoniasis tests accurate?
Currently, there are no clinical studies on the accuracy of at-home trichomoniasis testing. Companies that sell these tests typically claim they are accurate due to their use of accredited labs and physician reviews.
To ensure more accurate results, a person should follow all instructions in the test kit. Individuals should also follow up on any test results with a healthcare professional.
Is trichomoniasis included in standard STI testing?
Usually, a healthcare professional will test for certain STIs depending on the symptoms a person is experiencing and any risk factors. For example, the CDC recommends that men who have sex with men receive testing for HIV at least once a year.
If a person chooses to use an at-home STI test kit, they have the option of choosing from panel tests, which may include trichomoniasis, or tests that look for one or two specific STIs, such as gonorrhea and chlamydia.
Does trichomoniasis show up on a chlamydia test?
If a person purchases an at-home test for chlamydia or a healthcare professional only tests for this infection, trichomoniasis will not show up on the results.
Some at-home tests screen for more than one STI, and healthcare professionals may order more extensive testing, so a lab may use a single sample to check for trichomoniasis alongside other STIs.
Trichomoniasis is one of the most common STIs. The symptoms can include itching, discomfort, swelling, soreness around the genitals, and unusual discharge. However, these symptoms resemble those of many other conditions, and most people who get trichomoniasis do not have any symptoms.
The only way to be sure whether someone has this STI is to get a trichomoniasis test. People can get tests from healthcare professionals or use at-home tests. It is important to speak with a doctor to confirm the diagnosis and get appropriate treatment.
