STI screening: instructions for those who are concerned about their health
Sexually transmitted infections (STIs) may not show symptoms for a long time, but can cause serious harm to the body. Screening for STIs allows you to detect infections at an early stage and prevent the development of complications. In this article, we will tell you how to properly prepare for the examination, when it is worth undergoing it, and what diagnostic methods are used today.
What is STI screening?
Screening for STIs is a comprehensive laboratory test that helps determine the presence of sexually transmitted infections. Even in the absence of symptoms, the infection may be present in the body, so preventive screening is an important step towards maintaining overall health.
Who is recommended to undergo screening?
Screening is recommended in the following cases:
after unprotected sexual intercourse
with frequent changes of partners
when planning a pregnancy
when symptoms appear (strange discharge, pain, itching)
as part of an annual preventive examination
Main infections detected during screening
During a standard examination, they usually check for:
chlamydia
gonococci
HIV infection
viral hepatitis B and C
trichomonads
herpes simplex virus (as indicated)
How to prepare for the examination
Proper preparation will help avoid false results. Recommendations before taking the tests:
abstain from sexual intercourse 1–2 days before the examination
do not use intimate hygiene products the day before the test
It is advisable for women to avoid taking tests during menstruation.
It is recommended to refrain from urinating 2 hours before taking the smear.
How is the material taken?
Material for analysis is taken depending on the purpose of the study:
vaginal or urethral swab
blood sample from a vein
portion of first morning urine
scraping from mucous membranes
The process usually lasts a few minutes and is not accompanied by pain.
Diagnostic methods
The following methods are used in modern laboratories:
PCR (polymerase chain reaction) – detects the genetic material of the pathogen even in minimal amounts
ELISA (enzyme-linked immunosorbent assay) – determines the presence of antibodies or antigens
Bacteriological culture – helps determine the sensitivity of microorganisms to antibiotics
Smear microscopy – assessment of cell condition and presence of pathogenic microorganisms
Each of these methods has its own advantages, so combined approaches are often used to achieve the most accurate result.
When to get screened
Optimal screening times:
10–21 days after risky contact for PCR tests
after 1–3 months for antibody testing
annually with stable relations
every 3–6 months when changing partners or having an active sexual life
before a planned pregnancy for both partners
Regular check-ups are the best way to protect yourself and your loved ones.
What to do after receiving the results
If the result is positive, you need to:
consult an infectious disease doctor or dermatovenereologist
undergo full treatment according to recommendations
notify partner for joint examination and treatment
If the result is negative, it is worth continuing to follow preventive measures and getting checked regularly in the future.
Taking care of your own health is a responsibility to yourself and those around you. Screening for STIs is a simple procedure that can prevent serious consequences and help maintain the best quality of life.
