How Long Do STI Test Results Take?
Waiting for results can feel like the hardest part of any sexual health check. So, how long do STI test results take? The honest answer is that it depends on the infection being tested for, the type of sample taken and whether the test is read in the clinic or sent to a laboratory. Some results are ready before you leave, while others take a day or a few working days. This guide explains what to expect, so you can plan ahead and feel more at ease while you wait.
The Short Answer
Most STI test results come back within minutes to a few working days. Tests carried out during your appointment can give you an answer while you wait, often in around twenty minutes. Urine and swab samples sent to a laboratory, such as those used for chlamydia and gonorrhoea, are usually ready the next day at our clinic, as are most blood tests. A few tests, such as a gonorrhoea culture, take two to three days. Your clinician will always tell you which tests you are having and when to expect each result before you leave.
Why Some Results Are Quicker Than Others
Tests Read During Your Appointment
Some tests are designed to be read on site and can give a result in around twenty minutes, so you leave with an answer rather than waiting for a call. These tests are only suitable at the right point after a possible exposure, which is why we always ask about timing first.
Samples Sent to a Laboratory
Most STI testing relies on laboratory analysis. Urine samples and swabs are usually tested using PCR, a highly sensitive method that detects the genetic material of an infection. Blood samples may be checked for antibodies or antigens instead. Laboratory testing is very accurate, but collection, transport and processing all take time, which is why these results are not available on the spot. If you are new to testing, our guide to what an STI test checks for explains each type of sample in more detail.
Everyday Factors That Can Add Time
Results can also be affected by practical things, such as the time of day your sample is taken, weekends and bank holidays, or a sample that needs to be repeated. If a result is unclear, the laboratory may run it again to make sure it is correct, which is always better than giving you an uncertain answer.
Typical Turnaround Times by Infection
Chlamydia and Gonorrhoea
Chlamydia and gonorrhoea are usually tested together using a single urine sample or swab. At Sunshine Clinic, laboratory PCR results for these infections are typically available the next day. Some gonorrhoea checks can be read under the microscope during your appointment, while a culture, if one is needed, takes two to three days. Both infections often cause no symptoms at all, so a quick result means treatment can start sooner if it is needed. You can find out more about how our chlamydia tests work, and if gonorrhoea is confirmed, treatment can usually be arranged promptly.
HIV
HIV testing works a little differently, because the right test depends on how long ago a possible exposure happened, and some options can give you an answer during your appointment. The turnaround for each HIV test, and which one suits your timing, is set out in full on our HIV testing service page.
Syphilis, Hepatitis and Herpes
Syphilis and hepatitis B and C are checked with a blood test, and at our clinic these results are usually back the next day. On site tests for hepatitis B and C can also give an answer in around twenty minutes. Herpes is normally tested by gently swabbing a sore or blister, and your clinician will confirm when to expect that result. If you are booking screening for syphilis or a full sexual health check, we will confirm the expected date for every test included.
How Clinic, NHS and Home Kit Timings Compare
Where you test can make as much difference as what you test for. NHS sexual health services offer free testing, but appointment availability varies by area and results can take a week or more to come back. Postal home kits avoid a clinic visit, although posting your sample, having it processed and receiving your result can add several days. A clinic appointment combines on site testing with direct laboratory processing, which is why results are often quicker. Speaking to a clinician in person also means fewer unanswered questions while you wait.
Testing Too Early Can Mean Waiting Longer
The speed of a test is only half the picture. Every infection has a window period, which is the time between exposure and the point a test can reliably detect it. Testing too soon can give false reassurance and mean a repeat test later, so the quickest route to a reliable answer is testing at the right time. Chlamydia and gonorrhoea can usually be detected from around two weeks after sex, while blood tests for HIV and syphilis need longer. Our guide on when to get an STI test explains this in more detail.
If a possible HIV exposure happened within the last 72 hours, post-exposure prophylaxis (PEP) may be an option. It works best when started as soon as possible, ideally within 24 hours, so this is something to act on straight away rather than waiting to test.
How You Will Receive Your Results
Once your results are ready, we contact you promptly by telephone or email, using the method you agree at your appointment. Results from tests read in the clinic are explained to you in person before you leave. If everything is clear, that is the end of the process unless a repeat test has been advised. If you have not heard from us by the date you were given, please get in touch rather than assuming no news is good news.
If a result shows an infection, try not to worry. Most STIs are very treatable, particularly when they are found early, and we will explain what the result means in plain language and talk you through the next steps straight away, including referral to specialist care where that is the right route.
Frequently Asked Questions
Can I get STI test results on the same day?
Some results can be ready on the same day. Tests read during your appointment give an answer in around twenty minutes, while most urine and swab results for chlamydia and gonorrhoea follow the next day. We will tell you exactly when to expect each result before you leave.
Do all my results come back at the same time?
Not always. If you are tested for several infections, you may receive some results before others, because each test is processed differently. We will let you know which results to expect and when.
Is waiting for STD test results any different?
No. STD and STI describe the same infections, so the timings in this guide apply whichever term you use. Many healthcare professionals now prefer STI because some infections cause no disease or symptoms at all.
Why are my results taking longer than expected?
Delays are usually caused by a sample needing to be retested, laboratory demand, or a weekend or bank holiday falling within the processing time. A delay does not mean anything is wrong with your result. If you are concerned, contact us, and we will check on its progress for you.
Should I avoid sex while waiting for my results?
It is sensible to avoid sex, or to use condoms, until you have your results, especially if you have symptoms or a partner has told you they have an infection. This protects your partners and avoids passing an infection on before treatment.
