What Is an STI?
A sexually transmitted infection (STI) is an infection passed through sexual contact and caused by bacteria, viruses, fungi, or parasites. You may also hear the term STD, or sexually transmitted disease. The terms are often used interchangeably, but STI is more precise because an infection can be present without causing symptoms or developing into a disease.
Feeling Fine Does Not Rule Out an STI
Many sexually transmitted infections (STIs) cause no noticeable symptoms. Chlamydia and gonorrhea, for example, can remain unnoticed while still affecting a woman’s reproductive health. Testing is the only way to know whether an infection is present.
When symptoms do occur, they may include:
- Burning or pain during urination
- Unusual vaginal discharge
- Genital sores, bumps, itching, or irritation
- Pain during sex
- Pelvic or lower abdominal pain
- Bleeding between periods
Without treatment, chlamydia or gonorrhea can spread to the reproductive organs and cause pelvic inflammatory disease, commonly called PID. PID may lead to scarring, ongoing pelvic pain, ectopic pregnancy, or difficulty becoming pregnant later.
These symptoms can also have causes unrelated to an STI. A qualified medical provider must determine which tests are appropriate and diagnose the cause.
Who Should Ask About Testing?
Current CDC guidance recommends yearly chlamydia and gonorrhea testing for sexually active women younger than 25. Women 25 and older may also need annual testing if they have a new partner, multiple partners, or a partner who has an STI.
You may also want to contact a medical provider if a partner tested positive, you developed symptoms, or you may have been exposed recently.
Testing immediately after an exposure may be too early. The time between exposure and when a test can detect an infection is called the window period. Because that window differs by infection and test type, ask when to test and whether you may need to return.
One Sample Does Not Test for Everything
There is no single test that detects every STI. Depending on the infection and type of sexual contact, testing may involve:
- A urine sample or vaginal swab for chlamydia or gonorrhea
- A blood sample for HIV or syphilis
- A swab from a sore when herpes is suspected
- A throat or rectal swab when exposure occurred at those sites
An “STI panel” is not a universal package. Ask exactly which infections are included rather than assuming one sample tests for everything.
Why Testing Matters During Pregnancy
STI screening is a routine part of prenatal care. Medical providers generally test for syphilis, HIV, hepatitis B, and hepatitis C early in pregnancy. They may recommend additional testing based on your medical history, symptoms, or possible exposure.
If you are pregnant or think you may be pregnant, let the testing provider know. Some untreated infections can affect your health and the pregnancy, so the provider can determine which tests and treatments are appropriate.
Ask Before You Schedule
Before booking with an outside provider, ask:
- Which infections will I be tested for?
- How much will testing cost?
- How and when will I receive the results?
- What are the confidentiality and reporting policies?
- Is treatment available if a result is positive?
- Will I need to return for another test?
These details vary, so confirm them directly with the testing location.
Ask About Local Testing Referrals
Acts of Hope PRC does not test, diagnose, or treat STIs. Depending on availability, our team may be able to connect you with a local testing resource. Each provider determines its own costs, requirements, confidentiality practices, tests, scheduling, and treatment services.
Do not wait for a referral if you have severe pelvic or abdominal pain, fever, vomiting, fainting, or feel seriously unwell. Seek medical care promptly.
