Private STI Testing London - Same Day Results at 117a Harley Street

Reviewed byDr Mohammad Bakhtiar(GMC: 4694470)on 03/10/2026

Maybe a condom split at the weekend, or a new partner has suggested you both get checked. Or something just feels different, and you'd rather know this week than wait for an appointment to come free.

Private STI testing at Sexual Health Clinic London means you can usually be seen the same day at 117a Harley Street, London W1G 6AT. Booking is discreet, and your results come straight to you. If you already know what you need, book online, call the clinic first, or walk in.

What can you be tested for?

We test for chlamydia, gonorrhoea, HIV, syphilis, hepatitis B, hepatitis C, herpes, mycoplasma, ureaplasma, trichomoniasis, Gardnerella and HPV. Few people need all of them. The right tests depend on your symptoms, the kind of contact you had, and how long ago it was.

The sample follows the infection. Depending on what happened, that might be urine, a blood test, or a genital, throat or rectal swab. A doctor will tell you which ones are worth doing before anything is taken.

A combined chlamydia and gonorrhoea PCR test is £104. If you'd like wider cover, there are full STI screens for men and for women, plus broader panels for anyone who wants more infections checked in one visit.

How quickly will you get results?

On our standard tests and packages you get results for blood tests in about 24 hours, and urine and swab results within 3 working days.

If you need to know sooner, the FAST Screen returns all results in 6 hours. FAST Screen Simple is £350 and covers HIV, syphilis, chlamydia and gonorrhoea. FAST Screen Complex is £450 and adds hepatitis B and C.

Private testing or an NHS clinic?

NHS sexual health clinics serve many people well, though appointment availability and result times vary from area to area. People tend to come to us when they want a same-day appointment, a wider choice of tests, discreet payment, or a clinic on Harley Street.

Whichever you choose, the important part is getting tested. With us, results go directly to you, and if anything comes back positive, we arrange treatment with you.

When is it worth booking?

Book a test promptly if you've noticed discharge, a sore, pain when you pass urine or pelvic pain, or if you think you may have been exposed to an infection. It's also worth checking after a new partner, even when you feel completely well.

You can book online at sexualhealthclinic.london/book, call the clinic, or walk in.

For confidential testing and treatment, visit our private sexual health clinic in London. Same-day appointments and walk-ins available.
