Trichomonas Test (PCR): What It Looks For

This PCR test looks for the DNA of Trichomonas vaginalis, the parasite behind trichomoniasis. The sample is usually urine or a swab, not blood. It can offer clarity when you are unsure about possible symptoms.

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 can cause symptoms such as discharge or irritation, but it may also go unnoticed. Having this information can help you and a doctor decide on possible next steps. Testing can support clarity for both you and a partner.

When to Test

Testing is generally most reliable after symptoms appear or roughly 1 to 2 weeks after possible exposure. Testing very early may not yet give a dependable result. A doctor can help you decide on the right timing.

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.
