Can I have an STI without any symptoms?

Yes. Many sexually transmitted infections cause no symptoms, or symptoms may be mild and easy to miss. Testing is the only way to know whether an infection is present.

How soon after sex should I get tested?

Testing windows vary by infection and test method. Testing too early can miss an infection, but do not delay seeking advice if you have symptoms, a partner has tested positive, or the exposure was recent and you may need urgent prevention such as HIV PEP.

What sample will I need to provide?

It may be urine, a swab, a blood sample or a combination. The right samples depend on the infections being tested for, your symptoms and the sites of sexual contact.

What happens if a result is positive?

The team will explain the result and the next step. Depending on the infection, this may include treatment, a prescription, further testing, advice about partners or referral to a specialist sexual health service.

Your information is handled confidentially and would not normally be shared with your GP without your permission. As with any healthcare service, there are limited exceptions where disclosure is required by law or needed to protect you or someone else from serious harm.

Is free testing available elsewhere?

Yes. NHS and HSE sexual health services provide free, confidential STI testing and treatment. Jace Medical offers a private route for people who prefer to arrange testing through our team.

When to consider testing

You don’t need symptoms to get tested.

Sexual health testing is routine healthcare. You will be treated professionally, whatever has brought you here.

You have no symptoms

Many sexually transmitted infections cause no noticeable symptoms, so testing can be the only way to know.

You have a new partner

Testing before or during a new relationship gives both partners clearer information and reassurance.

You are concerned after sex

If a condom was not used or failed, the right advice depends on the exposure and how recently it happened.

You or a partner has symptoms

Discharge, pain when urinating, sores, rashes or unexplained bleeding should be assessed, not self-diagnosed.

The right screen for you

Testing isn’t one-size-fits-all.

The most useful test depends on when the contact happened, the type of contact, any symptoms and which infections need to be considered.

Commonly tested for: chlamydia, gonorrhoea, HIV, syphilis, hepatitis B and C, trichomonas, mycoplasma, or other infections relevant to your history.

Urine sample

Often used to test for infections such as chlamydia and gonorrhoea, depending on anatomy and exposure.

Swab sample

A clinician may advise a vaginal, throat, rectal or lesion swab, depending on the sites of contact.

Blood sample

Used for infections such as HIV, syphilis and hepatitis when these are included in the agreed screen.

Confidential throughout

Privacy without vague promises.

Your conversation, samples and results are handled as confidential medical information. We explain how information is used and discuss any follow-up with you.

Severe pain, heavy bleeding or feeling very unwell: Contact your local urgent-care service or emergency department, depending on severity.
After sexual assault: A sexual assault referral centre can provide specialist medical, practical and emotional support.
