What Do I Do After a Positive STI Test?

After a positive STI test, start by finding out exactly what the result means and what the next step is for that specific infection.

Panic can set in pretty quickly after a positive STI test result.

And then come the questions:

Do I need treatment? Can I still have sex? Who do I need to tell? Is this something that goes away? Does this mean I know who I got it from?

You don’t need to answer all of those immediately.

Start with something smaller:

What exactly came back positive, and what do the next steps look like?

Once you know that, the rest usually becomes much easier to sort through.

Find Out What the Result Actually Means

Sometimes a positive result gives your doctor enough information to move straight into treatment.

Other times, another test is used to confirm what the first one found.

So before you get too far ahead of yourself, make sure you understand what you’re actually looking at.

Is the result considered confirmed? Do you need another test? Or is the next step already treatment?

If you tested through a clinic or an at-home service with medical follow-up, whoever reviewed the result should be able to answer those questions.

You don’t need to figure out the whole situation yourself.

Treatment Depends on What Came Back Positive

Different STIs lead to very different next steps.

Some can be cured with medication. Others stay in the body but can be treated or managed.

You may be done with treatment after a short course of medication.

You may need ongoing treatment and a conversation about lowering the chance of passing the infection to someone else.

Or you may need another test before your doctor knows exactly what comes next.

Once you know what was actually found, you can stop trying to solve every possible version of the situation and deal with the one you're in.

Ask When It’s Okay to Have Sex Again

This is one of the practical questions worth getting answered early.

Feeling fine doesn’t necessarily mean you can’t pass an infection to someone else.

And there isn’t one waiting period that applies to every STI.

With some infections, you may need to finish treatment and wait before having sex again. A recent partner may need treatment too.

Others are managed differently because the infection stays in the body.

You don’t need to memorize the rules for every STI.

Just make sure you know which ones apply to the result you got before you have sex again.

You May Need to Tell Recent Partners

For a lot of people, this is the hardest part.

Depending on the infection, recent partners may need to know so they can get tested, treated, or both.

You don’t have to guess how far back you’re supposed to go. The doctor, clinic, or testing service handling your result can help you figure out who actually needs to be contacted.

And telling someone doesn’t require turning the conversation into a confession.

You’re giving them health information they may need to act on.

If figuring out what to say is the part you’re stuck on, this may help with the conversation.

The Test May Not Tell You Who You Got It From

A positive result can immediately make you start working backward.

Who did I get this from? How long have I had it? Does this mean my current partner gave it to me?

Those questions make sense.

But the test itself may not be able to answer them.

A lot of STIs can be present without causing obvious symptoms. You can find out you have an infection now without knowing exactly when you picked it up.

That means a positive result doesn’t automatically prove that the infection is recent.

And it doesn’t automatically tell you which partner it came from.

Sometimes your testing history and the timing of different relationships can give you useful context.

But be careful about asking the result to tell you something it actually can’t.

Treatment May Not Be the Last Step

Once you’ve taken medication or dealt with the immediate result, there may still be one more thing to keep track of.

Some infections need follow-up testing.

Sometimes that’s to make sure the infection is gone.

Other times, you may be asked to test again later because getting the same infection again is fairly common.

The timing depends on what you tested positive for.

So before you finish the conversation with your doctor or close the message from the testing service, ask:

Do I need another test, and if so, when?

If the answer is yes, put it on your calendar.

It’s an easy step to forget once the immediate stress of the positive result has passed.

What to Take Away

A positive STI result can feel enormous when all you know is that something came back positive.

It usually gets more manageable once you move past "I have an STI" and find out what the specific infection actually requires.

Find out exactly what came back positive and what the next step is for that infection. Then take it from there.
