Product information

The 4-in-1 STI Blood Test Kit is used to screen for HIV, hepatitis B and C, and syphilis, which are detected using a blood sample. It contains a lancet, which collects the required sample in a similar manner to a finger prick test. Testing is carried out by our partner lab, TDL pathology.

When your result is ready, TDL will send this to us, and our doctor will then contact you with your result. If you test positive for any of the STIs listed above, our doctor will also give you advice on what you need to do next and where to get treatment.

Please note that this kit does not test for: chlamydia, gonorrhoea, herpes, gardnerella vaginalis, trichomonas vaginalis, mycoplasma genitalium or ureaplasma. Testing for these is conducted using a urine test kit.

What are HIV, hepatitis and syphilis?

The human immunodeficiency virus, or HIV, is a condition which inhibits the function of the immune system. When it isn’t treated, it is a progressive illness which can develop into acquired immunodeficiency syndrome (AIDS), where the body becomes incapable of fighting off infections.

Hepatitis is an umbrella term used to describe inflammation of the liver. It can be caused by several factors, such as the use of certain medicines, or by a viral or bacterial infection. (However the term ‘hepatitis’ is more commonly used to refer to infections of the liver.) Hepatitis B and hepatitis C are viral infections, which can impede liver function.

In ‘acute’ cases, the body can rid itself of hepatitis B, but the virus can develop into a ‘chronic’ stage where prolonged or continuous treatment is required. Someone infected with hepatitis C may find that their body fights the virus off on its own, but if it doesn’t, treatment will be required to stop the infection from becoming chronic. In any case, someone with either infection will need to have their condition monitored during the first few months following diagnosis.

Syphilis is a bacterial infection. In someone who is infected, symptoms will tend to develop in three stages (primary, secondary and tertiary). Initially these tend to be minor (‘chancres’ or small sores, and a skin rash) but left untreated, it can lead to serious health problems such as stroke or blindness.

All of the above can be transmitted through unprotected sexual intercourse with an infected person. Hepatitis B can be spread through oral, anal or vaginal sex, or sharing used needles, as can syphilis, which can also be passed onto someone else through contact with an infected sore.

Hepatitis C and HIV can be transmitted via vaginal and anal sex, or sharing needles with an infected person. In theory, it is possible for HIV and hepatitis C to be spread through oral sex, but this is thought to be very rare.

Why do these STIs require a blood test?

When infected with these STIs, the antibodies the immune system generates to fight them is present in the blood. Some tests work by detecting these antibodies; if the antibodies are present, it means the virus is present. However, the tests we offer work slightly differently.

The 4-in-1 test screens for antibodies to detect a syphilis infection; but when screening for HIV and viral hepatitis, it looks for viral DNA and RNA cells produced by the virus (also found in the blood of an infected person).

In some cases, it can take up to several weeks for viral antibodies to develop. For example, someone who has been infected with HIV might not have detectable levels of antibodies until up to 12 weeks after exposure. Screening for DNA and RNA is usually better at detecting more recent infections.

In any case, someone who thinks they might have been exposed recently should always get a follow-up test to confirm a negative result.

How long does it take to get my result?

Once you have collected your sample and posted it back to our laboratory, they will usually turn around your result within 24 hours of receipt.

So, provided you collect your sample when receiving your test kit from us and post it back to our partner lab without delay, it’s possible to know your result within around five days of ordering the kit from our site.

Our doctor will get in touch to inform you of your result when it is ready. If you test positive for any of the above, they’ll advise you on where to get treatment.

How accurate is the 4-in-1 STI test kit?

The kit uses the same testing method as in NHS hospital labs. If you follow the instructions given with the kit correctly, it should be just as accurate as a test you get in a GUM clinic.

How can I order the 4-in-1 test kit online?

Click buy now to be taken to our simple order form. When your order is complete, we’ll post your test kit by next day courier, so you’ll normally receive it within one working day. Results are turned around at the lab within 24 hours of receipt, so it’s possible to know your result in a matter of days.

An illustrated copy of instructions will be supplied with your test. Make sure you follow these carefully. Not doing so may compromise sample collection and lower the accuracy of your test.

A video demonstration of how to collect your sample can also be accessed here:

  1. Fill in the form and label provided with a ballpoint pen.
  2. The side of the little finger is the ideal place to collect a sample from.
  3. Clean your hands with soapy warm water, then thoroughly dry with a towel.
  4. Position the sample collection tube upright in the wallet as shown in the diagram. Remove the cap.
  5. Use the alcotip wipe to clean the end of the little finger you’re using to take a sample, then dry with a tissue. The site must be completely dry, otherwise a blood drop will not form properly.
  6. Take out a lancet from it’s packaging, and twist the end off to reveal the puncture tip.
  7. Place this against the side of the little finger tip. Firmly press the lancet against the skin to activate it, and you should feel a small pinch.
  8. It is better to stand up when collecting your sample.
  9. If you cannot collect enough blood from the initial sample site, you should use one of the spare lancets to take a sample from your other little finger.
  10. A tiny drop of blood will collect at the puncture site. The first one will need to be wiped away with a clean tissue.
  11. With your hand facing downwards, massage the same side of your hand where your punctured little finger is to facilitate blood flow to the tip.
  12. Hold the tip of your finger over the open end of the tube, and allow the blood to drip in.
  13. Fill to the upper of the two lines on the side of the tube.
  14. If you can’t get enough blood to come out, you can try wiping the tip of the finger with a tissue, waiting for 5-10 seconds, and drops should begin to form once more.
  15. When you have filled the tube sufficiently, place the plaster top on the open end. Push this down to fasten it shut (you should hear a click).
  16. When the tip is secure, turn the tube up and down up to 10 times.
  17. Stick the label to the tube as shown in the diagram.
  18. Put the tube in the protective packing wallet and close.
  19. Insert the wallet containing the sample into the test kit box, along with any used lancets.
  20. Place the test kit box inside the envelope.
  21. Run through the instructions to make sure you’ve included everything you need to.
  22. Seal the envelope closed with the security sticker.
  23. Post back to The Doctors Laboratory as soon as possible.

If you have any questions regarding sample collection, or aren’t sure of anything, you can contact The Doctors Laboratory by email at, or by telephone at 020 7307 7373.

You can also contact us through your patient area, or on the phone number and email address listed at the bottom of this page.

Full STI (Blood) Test Kit


How does it work?

The test kit comes with a small lancet, which is used to take a sample of blood from the finger. This sample should then be sent to our partner lab in the prepaid envelope provided.

Who is your partner lab?

TDL Pathology, who are a UK-based lab. You can read more about them on their website.

How will I be notified?

We’ll notify you that your result is ready via text and email. You’ll then be able to view your result by logging into your patient area. In some cases, our doctor will need to discuss your result over the phone. If they do, they’ll contact you to arrange an appropriate time to call.

How long does it take?

You’ll usually receive your test kit in one working day when you order it from our UK pharmacy. Upon receipt of the sample, it normally takes our partner lab 24 hours or less to analyse the sample and send the result to us. This means that, as long as you provide the sample promptly upon receiving the kit, you should be able to know your result in less than a week.

What kind of sample do I have to give for the 4-in-1 test?

A blood sample. This is taken from the end of the little finger with a small lancet, provided in the pack.

Will it hurt?

It may pinch, but shouldn’t be very painful at all.

What happens if I’m negative?

You’ll be given some advice from our doctor on safe sex practices, and when you might need to get re-tested.

It can take up to 3 months for HIV to show up on a test, so people who think they may have been exposed recently are advised to have a follow-up test to verify a negative result.

What happens if I’m positive?

Our doctor will contact you with guidance on where to get treatment.

Are the conditions curable?

HIV is not curable, but is treatable with retro antiviral medicines. These work by suppressing the activity of the virus, and will need to be taken long-term.

Hepatitis B and C are curable if they’re identified and, where necessary, treated before they develop into chronic infections. However in chronic cases, they may need to be managed with medication long-term.

When syphilis is detected early, it can often be treated successfully with oral antibiotics. During later stages, hospital admission may be required, so that antibiotic medicine can be administered via an IV drip, and other symptoms can be monitored.

Who should get tested?

People who are sexually active should get routinely tested for STIs anyway. How often you get tested depends on your sexual preferences, but at least once a year is generally good practice.

However if you think you might have been exposed to any of the above, have any symptoms associated with an STI, or have been told by a sexual partner that they have received a positive result, you should get tested as soon as possible.
