Trichomonas vaginalis (DNA, qualitative)

Trichomonas Vaginalis (DNA-Qualitative)

We remind you that independent interpretation of the results is unacceptable, the information provided below is for reference purposes only.

Trichomonas vaginalis is a parasitic protozoan that causes trichomoniasis, a sexually transmitted infection. It is a flagellated, motile organism that primarily infects the urogenital tract in humans. Trichomoniasis is one of the most common non-viral sexually transmitted diseases worldwide.

Structure and Characteristics

Trichomonas vaginalis is a pear-shaped or oval-shaped organism, typically measuring around 10-20 micrometers in length. It has a single nucleus, four flagella (whip-like structures) that aid in locomotion, and an undulating membrane that helps the organism move and attach to host cells.

Trichomonas vaginalis is a parasitic organism that requires a host for survival and reproduction. It can survive in the urogenital tract of both men and women, but it more commonly causes symptoms in women. The organism adheres to the epithelial cells of the urogenital tract, causing inflammation and irritation.

Role of Trichomonas Vaginalis (DNA - Qualitative) in Diagnosis

The detection of Trichomonas vaginalis DNA plays a crucial role in the diagnosis of trichomoniasis, a sexually transmitted infection caused by the protozoan parasite Trichomonas vaginalis. This qualitative test helps identify the presence of the parasite's genetic material, enabling accurate diagnosis and appropriate treatment.

Indications for Ordering the Test

The Trichomonas Vaginalis (DNA - Qualitative) test is recommended in the following situations:

• Symptomatic individuals: Women experiencing symptoms such as vaginal discharge, itching, or irritation, and men with urethral discharge or discomfort during urination, may benefit from this test to determine if trichomoniasis is the underlying cause.
• Screening in high-risk populations: Individuals with multiple sexual partners, those with a history of sexually transmitted infections, or those engaging in unprotected sexual activity may be advised to undergo screening for trichomoniasis.
• Follow-up testing: After completing treatment for trichomoniasis, this test may be ordered to confirm the successful elimination of the parasite.
• Screening during pregnancy: Trichomoniasis can increase the risk of adverse pregnancy outcomes, such as preterm delivery or low birth weight. Screening is often recommended for pregnant women, especially in high-risk populations.

Preparation for the Procedure

Proper preparation is essential for accurate Trichomonas Vaginalis (DNA-Qualitative) test results. Here are some recommendations:

• Avoid douching or using vaginal products: Refrain from using vaginal douches, creams, or other products for at least 24-48 hours before the test, as they may interfere with the sample collection.
• Abstain from sexual activity: It is recommended to abstain from sexual intercourse for at least 24 hours before the test to prevent potential contamination of the sample.
• Schedule the test appropriately: Ideally, the test should be scheduled outside of menstrual periods to ensure accurate results.
• Inform your healthcare provider: Provide your healthcare provider with information about any recent treatments, medications, or conditions that may affect test results.

Procedure for Sample Collection

The sample for the Trichomonas Vaginalis (DNA-Qualitative) test is typically collected during a pelvic examination by a healthcare professional. The process involves gently swabbing or scraping cells from the vaginal walls or cervix using a sterile swab or brush.

About the Test

The Trichomonas Vaginalis (DNA - Qualitative) test is a nucleic acid amplification test (NAAT) used to detect the presence of Trichomonas vaginalis, a protozoan parasite that causes trichomoniasis, a sexually transmitted infection (STI). This test is highly sensitive and specific, making it a valuable tool for the diagnosis of trichomoniasis.

The test is typically performed on a vaginal swab or urine sample from women, and a urine sample or urethral swab from men. The sample is processed in the laboratory, where the DNA of the parasite is extracted and amplified using a technique such as polymerase chain reaction (PCR) or transcription-mediated amplification (TMA).

The Trichomonas Vaginalis (DNA - Qualitative) test is often included as part of a comprehensive STI panel, which may also include tests for other sexually transmitted pathogens like Chlamydia trachomatis, Neisseria gonorrhoeae, and Human Papillomavirus (HPV). This test can aid in the early detection and proper management of trichomoniasis, which is crucial for preventing complications and reducing the risk of transmission.

IMPORTANT!

It is crucial to remember that the information provided in this section is not intended for self-diagnosis or self-treatment. If you experience any symptoms or a flare-up of a condition, it is essential to consult a healthcare professional for proper diagnostic testing and treatment. Only a qualified specialist can make an accurate diagnosis and determine the appropriate course of treatment. To ensure the most accurate and consistent evaluation of test results, it is recommended to have tests performed at the same laboratory. This is because different laboratories may use different methods and units of measurement for similar tests.
