What happens if an STI result is positive

A positive result can feel like a shock, but for the great majority of STIs it is the start of a short, straightforward fix rather than a crisis. Knowing in advance what happens takes some of the fear out of it. No judgement, no assumptions: a positive result is a common, treatable medical finding, and you will be looked after through every step of it.

How you will be told

A positive result is delivered by a phone call from the doctor, not by text or email. The doctor explains what the result means, what it does not mean, and what happens next, and you will have the chance to ask questions. The call is calm and practical, and the first message is almost always the same: this is treatable, and here is the plan.

Most positives are quickly resolved

The common bacterial STIs are cured with antibiotics:

• Chlamydia is treated with a short course of antibiotic tablets, which clears it in over ninety-five percent of cases.

• Gonorrhoea is treated with a single antibiotic injection.

• Syphilis is treated with an antibiotic injection, with follow-up blood tests to confirm it has worked.

• Trichomonas is treated with a course of antibiotic tablets.

For these infections, the path from positive result to cured is usually a matter of days to a couple of weeks. Our article on treatment covers what is involved in more detail, including when a follow-up test is needed.

Some results lead to specialist care

A small number of results, mainly HIV and hepatitis C, point to conditions that need ongoing specialist management rather than a single course of treatment. If one of these comes back positive, the doctor explains it, supports you, and refers you promptly into specialist care, whether NHS or private. Modern treatment for these conditions is highly effective, and finding them early is a genuine advantage rather than something to dread.

It is more common than you might think

If you do get a positive result, you are in very large company. STIs are among the most common infections in the UK, chlamydia especially, and the people who test positive are not careless or unusual. They are people who had sex, which is to say most people. Framing a diagnosis as a routine, fixable event rather than a personal failing is not just kinder, it is accurate. The doctor treats it that way, and so should you.

What you will be asked to do

Alongside treatment, two practical things usually follow a positive result:

• Partner notification: letting recent partners know they should test, which can be done by you or anonymously on your behalf. We cover this in a separate article.

• Avoiding sex for a short period, until treatment is complete or, for some infections, until a follow-up test confirms the infection has cleared.

For some infections a test of cure is arranged to make sure treatment has worked. The doctor tells you whether you need one and exactly when to have it, so nothing is left vague.

How long until you are in the clear

It depends on the infection. For chlamydia, treatment works quickly and a test of cure is not usually needed unless you are pregnant or symptoms persist. Gonorrhoea has a follow-up test at the right interval after treatment. Syphilis is tracked with blood tests over several months to confirm the infection is resolving. The doctor maps out the timeline with you so you know what each follow-up is for.

A positive result for one infection is also a good moment to make sure the rest of your screen is complete and to time any tests still inside their window. The doctor joins these threads up so you leave with a clear plan rather than loose ends.

The honest summary

You will hear about a positive result by phone, from a doctor who will explain it and arrange treatment. Most STIs are cured quickly. The few that need specialist care are referred without delay, and early diagnosis helps. A positive result is a manageable step, and you will not be left to deal with it alone.
