STD

Trichomoniasis (PCR)

The Trichomoniasis test detects the Trichomonas vaginalis parasite, which causes trichomoniasis, the most common curable sexually transmitted infection globally. The infection is often asymptomatic, particularly in men, making testing essential for detection.

What It Measures

This test detects the presence of Trichomonas vaginalis, a single-celled parasitic organism that infects the urogenital tract. Depending on the testing method, it may identify the parasite through microscopy, culture, antigen detection, or nucleic acid amplification.

Nucleic acid amplification tests (NAATs) offer the highest sensitivity and can detect the parasite even when present in very low numbers. The test can be performed on various sample types depending on the collection method.

Why It Matters

Trichomoniasis, while readily curable, can cause uncomfortable symptoms such as discharge, itching, and irritation. When left untreated, it may increase susceptibility to other sexually transmitted infections, including HIV, and can be associated with adverse pregnancy outcomes.

Because trichomoniasis is so frequently asymptomatic, many infections go undetected without specific testing. Identifying and treating the infection protects both your health and the health of your sexual partners.

When to Test

Testing is recommended for individuals experiencing symptoms such as abnormal discharge, genital itching or burning, or discomfort during urination or sexual intercourse. It may also be included in a comprehensive STI panel for sexually active individuals.

Screening may be particularly recommended for women with new or multiple sexual partners, individuals with a history of STIs, or during pregnancy. Men are less commonly screened but should be tested when symptoms are present or a partner has been diagnosed.

Recommendations

Male

If Low

Not detected result indicates no trichomoniasis infection. Continue safe sexual practices.

If High

Detected result requires antibiotic treatment (typically metronidazole). Notify partners and abstain from sexual activity until treatment is completed.

Female

If Low

Not detected result indicates no trichomoniasis infection. Continue safe sexual practices.

If High

Detected result requires antibiotic treatment (typically metronidazole). Notify partners and abstain from sexual activity until treatment is completed.

Lifestyle Tips

Consistent condom use is the most effective way to prevent trichomoniasis transmission. If diagnosed, both you and your sexual partner should be treated simultaneously to prevent reinfection, as the infection can easily pass back and forth.

Complete the full course of prescribed medication even if symptoms resolve before treatment is finished. Avoid sexual contact until both partners have completed treatment. Regular STI screening supports early detection and helps maintain sexual health.

Frequently Asked Questions

Can men get trichomoniasis?
Yes, men can be infected with trichomoniasis, though they are more likely to be asymptomatic than women. When symptoms do occur in men, they may include irritation inside the penis, discharge, or burning after urination. Men should be tested when a partner is diagnosed.
Why do both partners need treatment?
Both partners must be treated simultaneously to prevent reinfection. If only one partner is treated, the untreated partner can pass the infection back. This is sometimes called a "ping-pong" effect.
Can trichomoniasis affect pregnancy?
Untreated trichomoniasis during pregnancy may be associated with premature delivery and low birth weight. Screening during pregnancy allows for safe treatment that protects both mother and baby. Consult your healthcare provider for guidance.
