What can I learn
from this test?

With our blood and urine test, you can understand if you're infected with one of the following six common sexually transmitted infections (STIs), including chlamydia, gonorrhoea, HIV, syphilis, hepatitis B, and trichomoniasis.

Many STIs don't cause any symptoms, or the symptoms can be mild and overlooked. So, an STI test is the only way to see whether you are infected. An untreated sexually transmitted infection can lead to medical problems or the STI being spread. That's why it's important to get checked, especially if you have had unprotected sex, sex with someone whose medical history is unknown to you, or if you are changing sexual partners. Most STIs can be treated with a course of antibiotics.

We explain more in our blog, five surprising facts you didn't know about STIs.

What are
chlamydia, gonorrhoea, and HIV?

Chlamydia is a common infection that can affect men and women and is caused by the bacterium Chlamydia trachomatis. It often doesn't produce any symptoms, but it can spread to the uterus and fallopian tubes where it can cause pelvic inflammatory disease, a leading cause of infertility.

Gonorrhoea is caused the bacterium Neisseria gonorrhoea. You may notice a discoloured and bad-smelling discharge from the vagina or penis and a burning sensation when you urinate. Up to 50% of women and 10% of men may have no symptoms.

HIV (human immunodeficiency virus) lives in the bodily fluids of infected people - including semen, vaginal fluids, and blood. It is most commonly transmitted through unprotected sex with an infected partner. HIV damages your immune system making it harder to fight infections and diseases. Although there is no cure for HIV, current treatment means that many people with HIV live healthy lives.

What are
syphilis, hepatitis B, and trichomoniasis?

Syphilis is passed from one person to another during sex. Syphilis progresses in stages with different symptoms, although some of these may be mild. Symptoms include sores and skin growths around the anus and genitals, a blotchy rash, joint pain, and fever. Without treatment, syphilis can damage vital organs such as the brain, heart, nerves, liver, and bones.

The hepatitis B virus often has no symptoms, and many people recover from infection without treatment. However, if hepatitis B becomes long-lasting, it can cause severe liver scarring (cirrhosis) and cancer. Symptoms of hepatitis B include nausea, diarrhoea, stomach pain, and flu-like symptoms. Having unprotected sex or sharing needles increases your risk of getting hepatitis B.

Trichomoniasis is caused by a parasite that infects the vagina and urethra (the tube that passes urine). Most people infected by trichomoniasis have no symptoms and don't know they are infected. Symptoms could include discharge from the vagina or penis, itching or soreness in the genital areas, and discomfort when urinating. Pregnant women who are infected may also experience complications. Having a trichomonas infection increases the risk of getting and spreading other STIs.

HIV - 1 and HIV - 2 antibodies and P24 antigen

HIV antibodies are made by the immune system in response to infection with either Human Immunodeficiency Virus type 1 or 2. P24 antigen is a protein from the core of the HIV virus, it is found during the initial infection with HIV and disappears following seroconversion. This test will look for the presence of HIV antibodies and p24 antigen in the blood and will report whether they are detected or not.

Syphilis antibodies Syphilis is a sexually transmitted disease caused by the bacterium Treponema pallidum, spread through sexual contact. Which is important to test for and treat as the infection can cause a range of health problems if left untreated. Antibodies are produced by the immune system when there is an infection in the body. Checking for syphilis specific antibodies in the body helps to identify an infection.
Hepatitis B surface antigen The hepatitis B surface antigen (HBsAg) is a protein on the surface of the hepatitis B virus, present in the blood during a hepatitis B virus infection. Checking for this surface antigen helps to identify acute and chronic HBV infections. Positive surface antigen meaning the virus is present and that the individual is infectious.
C trachomatis PCR Chlamydia which is caused by the bacterium Chlamydia trachomatis, is the most common bacterial sexually transmitted disease in the UK, passed on through unprotected sex and can also be passed by a pregnant woman to her unborn baby. Chlamydia doesn't usually cause any symptoms but if left untreated, the bacteria can spread around the body and lead to long-term health problems. This test looks for small amounts of the genetic material (DNA) of Chlamydia trachomatis to help identify a current, active infection. This is a sensitive test that can identify even very small amounts of bacterial DNA.
N gonorrhoeae - NAAT Gonorrhoea is a sexually transmitted infection caused by the Neisseria gonorrhoeae bacteria, passed on through unprotected sex. This test looks for small amounts of the genetic material (DNA) of Neisseria gonorrhoeae to help identify a current, active infection. This is a sensitive test that can identify even very small amounts of bacterial DNA.
T vaginalis PCR Trichomoniasis is a sexually transmitted infection caused by the Trichomonas vaginalis parasite. It is the most common protozoan infection in industrialised countries. It is transmitted during unprotected sex and whilst it can cause symptoms such as vaginal discharge and irritation in women it often causes no symptoms, this particularly true in men. This test looks for small amounts of the genetic material (DNA) of Trichomonas vaginalis to help identify a current, active infection. This is a sensitive test that can identify even very small amounts of the parasite's DNA.

for your test?

Special Instructions

Prepare for your 6-in-1 STI Blood and Urine Test by following these instructions. If there is a chance that you have been exposed to HIV, hepatitis B or C then please let us know how long before taking your sample this occurred. Your sample should be taken 4 weeks after any hepatitis B exposure. Take your test at least 4 weeks after any possible HIV exposure, a repeat test is recommended at 12 weeks. Do not take biotin supplements for two days before this test, discuss this with your doctor if it is prescribed.
