Many people with sexually transmitted infections (STIs) have no symptoms.
STIs can pass from one person to another during sex, especially if you don’t use a condom.
It is a good idea to get tested, particularly if you have recently changed partners.
Most infections can be cured. If you are diagnosed with an STI you should avoid having sex with anyone until you have completed treatment. If you do have sex, the infection could be passed to your sexual partner.
Worried about taking your own blood sample? Watch our top tips video.
These top tips are from people who have completed the test kit.
To help you prepare:
- relax and be patient (it can take longer for some people than others)
- if you’re nervous, ask someone to be there with you
- watch the instruction video and read the instruction leaflet (we know people find the test easier to complete after watching the video)
- tie long hair back and take off any scarves or jewellery that could get in your way
- lay the test kit items and your two tissues on a clean, flat surface below your waist.
To help blood flow to your finger:
- take a hot shower or bath, or hold your hand under warm water for a few minutes, (when your hands are warm, blood flows easier)
- stay standing and keep your arm straight with your hand below your waist
- aim for the middle of the tip of your finger, not too close to your fingernail
- push lancet down hard against your finger
- wipe the first dot of blood away with a clean tissue to stop the blood congealing
- if your finger dries up, wait a while, warm up your hand, use another finger and make sure you press the lancet down hard against your finger.

Every test kit has to be sent back to the lab for analysis. There’s a grey freepost return envelope included. Your details will not appear on any of the samples or the freepost envelope, as Fettle is completely confidential.
We will keep you updated by text message. We will send a text when your test kit has been dispatched to you and when the lab receives your samples.
We will text you your test results as soon as possible - always within 7 days. If you do have an infection, we will advise you of how to get treatment and further support.
If you have any other infection, we will advise you how to get treatment and further support. In some cases, one of our clinicians may call you to offer additional advice.
If you receive a positive chlamydia test result from Fettle, we will offer you free treatment and deliver it by 1st class Royal Mail. Before we prescribe, you will need to complete a short online form, answering questions about you and your health history.
Typically, treatment will include a course of antibiotics, and may require you to attend a clinic in person. Find your nearest sexual health clinic .
We will track your order and will text you when your order has been dispatched, when it has been delivered to your address and when your samples have been received by the lab.

Regardless of whether you have an infection or not, only our clinicians and service managers will see your test results. All our staff sign a data protection agreement, similar to that used by NHS staff. Your results will never be shared with anyone else without your permission.
STI symptoms vary from obvious itchiness, soreness, rashes or redness, to pain when passing urine, discharge from the penis or vagina, and lumps or sores on the genitals. Some symptoms may also be internal - for example, pain inside your stomach or groin.
Sometimes you will get no symptoms at all or the symptoms will take a long time to show. This means you could be passing infections on to other people without knowing it.
The only way to know you have an infection is to have an STI test.
Clinicians often refer to ‘window periods’ when testing for STIs. This means the length of time it takes from catching an infection to it showing up on a test. The window periods for the tests we use are shown below.
Chlamydia and gonorrhoea tests are most accurate 2 weeks after potential exposure.
HIV tests are most accurate 4 weeks after potential exposure.
It is best to wait 4 weeks after potential exposure to take a Hepatitis B and / or Hepatitis C test, but in some cases it can take up to 6 months for the infection to show in results.
Syphilis tests are most accurate 12 weeks after potential exposure.
If you are in any doubt about window periods, you should do a test now, and another test at a later date.
If you think you are at risk of contracting HIV, preventative medication (PEP) is available but must be started within 3 days of exposure.
If you had unprotected sex and think you have a chance of being pregnant, you may want to consider emergency contraception.
There are two types of hormonal emergency contraceptive pill (also known as the morning after pill); one which has to be taken within three days of unprotected sex, and the other within five days. The non-hormonal coil (IUD) is the most effective emergency contraception if inserted up to five days after unprotected sex.
Sexually transmitted infections (STIs) are caused by bacteria, viruses or parasites that can be passed from one person to another during sex or intimate contact.
Most STIs are passed between sexual partners through unprotected oral, vaginal or anal sex - especially if you don’t use a condom.
Condoms are the only contraceptive method that protect against sexually transmitted infections (STIs).
You can get condoms free from the NHS - ask your local sexual health clinic or your GP. Alternatively you can buy condoms from most pharmacies and many supermarkets.
You will also see condoms in vending machines in pubs and clubs, and available to order online. Make sure to check the use-by date on the packaging, and always use condoms with CE marking. This means they have been tested to European safety standards.
If you are going abroad, take your favourite CE marked brand from the UK. That way you won’t have to rely on a local brand which could be packaged in a foreign language or which may not have been produced to the same standards.
