STI Testing in Ireland — The Complete Guide

Everything you need to know, in plain language. No shame, no judgment, no jargon.

If you are reading this, you are already doing the smart thing. Most people in Ireland never look this up — they wait until they're worried, then panic-search at 2am. You are ahead. This page is the one-stop hub for everything sti.ie covers: what an STI actually is, whether your symptoms (or lack of them) mean anything, what happens at a free HSE clinic, where to go in your county, and detailed plain-language info on every common STI in Ireland.

Free help, right now

Call the HSE Sexual Health Line free on 1800 700 700 (Mon–Fri 8am–8pm, Sat 9am–5pm). It's anonymous. Or order a free HSE home test kit at sh24.ie — anyone 17+ in Ireland.

Start here: the four pillar guides

If you only read four pages on this site, read these. They answer the questions almost everyone has before they make an appointment.

What is an STI?

The plain-language definition, the difference between STI and STD, and the most common ones in Ireland. Read this if you're new to all of it.

Symptoms — or not?

How to tell what's an actual symptom, what's anxiety, and when to test. Most STIs in Ireland have no symptoms at all.

How testing actually works

Walk-in or appointment? What do they ask? Swab or pee or blood? How do results come back? The whole thing demystified.

Testing directory

Every free HSE clinic and home-test option in Ireland, with phone numbers and addresses.

Not sure if it's an STI?

Plenty of things look or feel like an STI but aren't. Most common cause of confusion:

Thrush vs STI — the difference

Thrush is a yeast infection, not an STI. Plain-language guide to symptoms in men and women, where to test in Ireland, OTC treatment, when to see a GP.

Bacterial vaginosis

Also not technically an STI but routinely checked alongside. Different smell, different treatment.

The bit other STI sites skip — the emotional and social side

Testing is free and the medicine is straightforward. What stops most people is the anxiety, the conversation with a partner, the worry about who finds out, and the shame the culture still attaches to all of this. These six pages tackle that head-on.

Your first test

What actually happens — the room, the questions, the samples, the results. Plain language, nothing left out.

Dealing with anxiety

What anxiety does in this exact situation, what helps in each stage, and when to seek separate support.

Telling a partner

Scripts for current, past, and new partners. How HSE anonymous notification works if you cannot face the conversation yourself.

If you test positive

The first 24 hours, calmly. Five things to do, what each diagnosis means in 2026 Ireland, and what NOT to do.

Who finds out

Honest answer on GP file, insurance, employer, family. Different routes leave different paper trails — here is the map.

The stigma question

Where it came from, what it costs, and how to step past it for yourself and for a friend.

If a page sounds like it's for you

Some people want the general explanation. Some want the version written for their situation. These three are for the second group.

For students

Where on or near TCD, UCD, UCC, UoG, UL, DCU and the rest. College health services, drop-ins, anonymity.

For men

Men test less, get diagnosed later, and pass things on for longer. Plain-language symptoms and where to go
