Package "STI detection by PCR in prostate secretion"
Absolute pathogens are microorganisms whose presence in the urogenital tract always indicates the presence of infection, regardless of clinical manifestations. These pathogens are not part of the normal microflora and therefore require mandatory treatment even in the absence of symptoms.
Why is it recommended to take a PCR test for STDs from semen or prostate fluid?
More accurate detection of infection
Unlike urine or urethral swabs, semen is formed with the participation of:
- the prostate gland,
- the seminal vesicles,
- the epididymis.
If the infection is localized in the deep parts of the reproductive system, as in chronic prostatitis, a urine test may not reveal the presence of pathogens. However, they can be detected in ejaculate or prostate secretions.
Heightened informative value in sluggish inflammation
In chronic diseases (e.g., chlamydia, mycoplasmosis), the concentration of pathogens in the urethra is often low. Sperm passing through all glandular structures accumulates information about the infection and ensures higher test sensitivity.
Comfort and safety
- The procedure is less traumatic than a urethral swab.
- There is no risk of damage to the mucous membrane or painful sensations.
- No tools required – biomaterial is collected naturally.
Reducing the risk of false negative results
Errors in smear or urine collection may be caused by:
- superficial scraping,
- flushing out pathogens with urine,
- improper preparation.
This often leads to inaccurate results. Semen and prostate secretions are more reliable materials.
What infections does PCR testing detect:
- Chlamydia trachomatis (chlamydia)
- Neisseria gonorrhoeae (gonococci)
- Trichomonas vaginalis (trichomonads)
- Mycoplasma genitalium (mycoplasma genitalium)
When should you undergo analysis:
- if you experience burning, itching, or discharge from the urethra;
- after unprotected sexual intercourse;
- when planning a family
- for control after treatment of STDs.
Possible biomaterials:
- Ejaculate (sperm),
- Prostate secretion (obtained after prostate massage).
Preparation before submission:
- 48 hours - abstinence from sexual intercourse,
- the test should be taken no earlier than 2-3 weeks after completing a course of antibiotics.,mandatory hygiene of the genitals and hands before donation.
