Trichomonas vaginalis (Trichomoniasis): PCR-quantitative determination (s/g scraping)

Rules for preparing patients for a vaginal scraping in women

– Abstain from sexual intercourse for 3 days.
– Refrain from alcohol and spicy food for 3 days.
– Submit the material for examination before, or no earlier than 14 days after the end of the course of medical therapy (antibacterial and antifungal drugs), unless otherwise recommended by the doctor.
– During the day, refrain from using local dosage forms (suppositories, ointments, douches, contraceptives, etc.) and intimate hygiene products containing bactericidal additives.
– If the scraping will be performed from the urethra, do not urinate for at least 3 hours before taking the material.
– The material cannot be donated during menstruation (only 3 days after its end).

Rules for preparing patients for urinalysis in men

– Abstain from sexual intercourse for 3 days.
– Refrain from alcohol and spicy food for 3 days.
– Submit the material for examination before, or no earlier than 14 days after the end of the course of medical therapy (antibacterial and antifungal drugs), unless otherwise recommended by the doctor.
– Refrain from using local medications and procedures during the day.
– Immediately before taking the test, refrain from urinating for 2-3 hours.

Trichomoniasis is one of the most common sexually transmitted infections, caused by the microorganism Trichomonas vaginalis. This infection can have serious consequences for the health of women and men, so it is important to identify and treat it in a timely manner. Diagnosis of trichomoniasis plays a key role in controlling the spread of this disease. In this article, we will review the methods for diagnosing trichomoniasis and the importance of the infection panel.

Diagnosis of trichomoniasis:

Diagnosing trichomoniasis can be difficult because many people infected with Trichomonas vaginalis may be asymptomatic. However, if you have symptoms such as discharge, itching, burning, or pain during urination, you should definitely get tested.

1. Microscopy of scrapings: One of the main methods for diagnosing trichomoniasis is scraping microscopy. The doctor collects a sample of secretions from the affected areas of the mucous membrane. The sample is then examined under a microscope to detect and identify Trichomonas vaginalis. This method is relatively quick and affordable, but it can give false results, especially if the sample was collected incorrectly or the infection is latent.
2. Polymerase chain reaction (PCR): PCR is a biomolecular method that can detect Trichomonas vaginalis DNA even in cases where it is present in low concentrations in the sample. This method is very sensitive and specific, but requires specialized equipment and trained laboratory personnel.

Infectious Panel:

An infection panel is a group of tests that can be used to detect multiple infections at once. It becomes especially important for diagnosing trichomoniasis because this infection can coexist with other sexually transmitted infections, such as chlamydia, gonorrhea, or HIV. An infection panel allows you to test for multiple infections at once, saving time and effort for both the patient and the doctor.

Typically, an infectious disease panel includes the following tests:

1. Diagnosis of trichomoniasis using scraping microscopy or PCR.
2. Chlamydia and gonorrhea tests, that help identify other sexually transmitted infections.
3. HIV and syphilis testing, as these infections can also be sexually transmitted and have serious consequences.

The infection panel allows for accurate and rapid identification of infections, which helps the doctor provide an appropriate treatment regimen for each patient.

If you suspect trichomoniasis or other sexually transmitted infections, it is important to see a doctor for diagnosis and treatment. It is advisable to wear condoms during sexual intercourse and undergo periodic medical examinations to prevent infections and maintain your own health.
