The STI and Viral Hepatitis Blood Test is a comprehensive blood screening designed to detect key sexually transmitted infections and viral hepatitis through targeted antigen and antibody testing. This panel includes tests for HIV 1 & 2 (detecting both antibodies and p24 antigen for earlier identification), syphilis (antibodies to Treponema pallidum), hepatitis B (surface antigen for active infection), and hepatitis C (antibodies indicating exposure). These infections can lead to severe health issues if untreated, such as chronic liver disease, organ damage, and increased cancer risk, but early detection allows for effective management and prevention of complications.

A private STI blood test that screens for HIV, syphilis, hepatitis B and hepatitis C from one venous blood sample. These four infections are tested through blood, which is why they are grouped together in this panel.
This sexual health blood test checks for four infections that can be passed on through sex or blood: HIV, syphilis, hepatitis B and hepatitis C. It is sometimes called a blood-borne virus (BBV) screen or a sexual health blood screen.
It is a blood-only panel. That makes it a focused STI blood test, not a complete sexual health check. Some common infections, such as chlamydia and gonorrhoea, are tested with a urine sample or swab instead, so they are not part of this test. We explain exactly what is and isn’t covered below, so you can be sure you’re booking the right test.
A fourth-generation HIV test that looks for HIV-1 and HIV-2 antibodies and the p24 antigen.
Looks for antibodies to syphilis in your blood. Antibodies can remain after a past, treated infection, so results are read alongside your history.
Looks for current hepatitis B infection. The HBsAg test does not check whether you are immune to hepatitis B from vaccination.
Shows whether you have ever been infected with hepatitis C. A positive result needs a further test to check for current infection.
This test is for blood-borne infections only. It does not test for:
Chlamydia and gonorrhoea are tested with a urine sample or swab. Trichomonas is usually tested with a swab. Herpes is tested with a swab taken from a sore. Mycoplasma genitalium is usually only tested if you have symptoms.
NHS sexual health clinics test for these infections, and free home test kits for chlamydia and gonorrhoea are available in many areas.
Different infections are found in different samples. This table shows how each common STI is usually tested, and whether it is included in this panel.
| Infection | Usual sample | In this test? |
|---|---|---|
| HIV | Blood | Yes |
| Syphilis | Blood | Yes |
| Hepatitis B | Blood | Yes (HBsAg) |
| Hepatitis C | Blood | Yes (antibody) |
| Chlamydia | Urine or swab | No |
| Gonorrhoea | Urine or swab | No |
| Trichomonas | Usually a swab | No |
| Herpes | Swab from a sore | No |
| Mycoplasma genitalium | Urine or swab, usually if you have symptoms | No |
People often book a private STI blood test when they:
Many sexually transmitted infections cause no symptoms, so testing is the only way to know. If you do have symptoms, such as unusual discharge, pain when passing urine, sores, a rash or lumps, visit a sexual health clinic or your GP, as you may need an examination and urine or swab tests too.
After a possible exposure, it can take time for an infection to show up in a blood test. This is called the window period, and it is different for each infection. If you test too soon, a negative result may need repeating later.
If you’re unsure when to test after a specific exposure, ask a sexual health clinic or your GP, or call our team on 01277 652067.
If you have not had a recent possible exposure, you can book whenever suits you. Some people test when they start a new relationship, or as part of looking after their sexual health.
If you think you were exposed to HIV in the last 72 hours, don’t wait to book a blood test. Go to a sexual health clinic or A&E straight away and ask about post-exposure prophylaxis (PEP), which needs to be started as soon as possible.
Screening tests are designed to pick up possible infections. A reactive result means further testing is needed. It does not confirm that you have an infection.
If a result is reactive, contact your GP or a local sexual health clinic. They can arrange confirmatory tests and, if needed, treatment and support.
If an infection is confirmed, a sexual health clinic can help you let recent partners know, so they can get tested too.
Fertility clinics often ask for screening for HIV, hepatitis B, hepatitis C and syphilis before treatment. These are the four infections in this panel.
Before booking, check the exact tests your fertility clinic needs and how recent the results must be. Some clinics also ask for markers that are not included in this panel. If you’re unsure, call our team on 01277 652067.
You do not need to fast for this test. You can eat and drink as normal.
Do not stop prescribed medication unless advised by an appropriate healthcare professional.
If you are testing after a specific exposure, check the timing first so your result is as useful as possible.
You don’t need a GP referral to book. Check the current booking information for results timing, or call 01277 652067.

It screens for HIV (HIV 1 & 2 antigen/antibody), syphilis (syphilis serology), hepatitis B (hepatitis B surface antigen, HBsAg) and hepatitis C (hepatitis C antibody), using one venous blood sample.
No. This is a blood-only test for HIV, syphilis, hepatitis B and hepatitis C. It does not test for chlamydia, gonorrhoea, trichomonas, herpes or Mycoplasma genitalium, which need urine or swab samples.
HIV, syphilis, hepatitis B and hepatitis C are tested with a blood sample. Chlamydia and gonorrhoea are tested with a urine sample or swab, trichomonas is usually tested with a swab, and herpes is tested with a swab taken from a sore.
The panel includes a fourth-generation HIV 1 & 2 antigen/antibody test, which looks for HIV-1 and HIV-2 antibodies and the p24 antigen.
The test looks for hepatitis B surface antigen (HBsAg), which is a marker of current hepatitis B infection. It does not show whether you are immune to hepatitis B from vaccination.
A positive hepatitis C antibody result shows that you have been infected with hepatitis C at some point. It does not confirm a current infection, so a further test is needed. Speak to your GP or a sexual health clinic.
It can take time for an infection to show up in a blood test, and this window period is different for each infection. If you test too soon, you may need to repeat the test later. Ask a sexual health clinic or your GP about timing. If you think you were exposed to HIV in the last 72 hours, go to a sexual health clinic or A&E straight away and ask about PEP.

Yes. Many sexually transmitted infections cause no symptoms, so testing is the only way to know. If you do have symptoms, visit a sexual health clinic or your GP, as you may need an examination and urine or swab tests as well.
A reactive screening result is not a diagnosis. It means further testing is needed. Contact your GP or a local sexual health clinic, who can arrange confirmatory tests and, if needed, treatment and support.
