Trichomonas (Female)



Quest Diagnostics Test Code: 19550

Trichomonas Vaginalis is a parasite which causes infections of the genitourinary system in both men and women and is considered a sexually transmitted disease (STD). In women, it can cause infections inside the vagina and urethra. It is important to get tested for this because 30% of people infected do not show any symptoms. This test involves taking a sample of urine or secretions from inside the penis. The urine sample is more favorable, because the secretion sample involves pushing a swab inside the urethra and can be painful. The sample is checked for the presence of the parasite to make a positive diagnosis.

This test is performed in following conditions such as:

• Foul-smelling discharge
• Frequent urge to urinate
• Itching of inner thighs
• Discomfort during intercourse
• Burning after urinating or ejaculating

Also Known As: Trich, Trichomoniasis
