Overall Assessment
Five infections tested. None was detected.
Chlamydia and gonorrhea were tested by PCR, which detects the bacterium's own genetic material. Syphilis, HIV and hepatitis B were tested in blood. All five results were reviewed by a BIG-registered doctor.
Key Findings
No infections detected
GoodChlamydia, gonorrhea, syphilis, HIV and hepatitis B were all not detected.
Mind the window period
InformationalA test can only detect an infection once the window period has passed. For HIV with this fourth-generation test that is usually six weeks; for syphilis likewise around six weeks. If a risk contact was less than six weeks ago, repeating after that period is worthwhile.
Tested is not the same as protected
InformationalThis result describes the moment the sample was taken. It says nothing about contacts since.
Detailed Analysis
STD
NormalChlamydia and gonorrhea were tested by PCR. This method detects the bacterium's DNA and is more sensitive than culture. The window period is short: roughly two weeks after the risk contact the result is reliable.
Syphilis was tested with an antibody screening test. Antibodies only become detectable after some weeks; around six weeks after contact the result is reliable.
HIV was tested with a fourth-generation test, which detects both antibodies and the p24 antigen. Because p24 appears earlier than antibodies, the window period is shorter than with older tests: usually six weeks.
Hepatitis B was tested with HBsAg, the virus's surface antigen. An undetected HBsAg excludes active infection, but says nothing about vaccination status or a past infection.
Recommendations
Repeat after a recent risk contact
If the risk contact was less than six weeks ago, repeat the HIV and syphilis tests after those six weeks. Chlamydia and gonorrhea are already reliable after about two weeks.
If you want to know whether you are protected against hepatitis B
That requires anti-HBs, a different test from HBsAg. HBsAg answers "do I have it now"; anti-HBs answers "am I protected against it".
Next Steps
With these results no treatment and no follow-up testing are needed.
Contact your GP or a sexual health clinic if symptoms appear, or if you are unsure whether the risk contact fell within the window period. This report stays in your own account only.

STD
4What It Measures
This test uses polymerase chain reaction (PCR) technology to detect even very small amounts of Chlamydia trachomatis DNA in a sample. By amplifying genetic material, it can identify an active infection with high accuracy. Unlike antibody tests, a PCR test directly detects the presence of the bacterium, making it the most reliable method for confirming a current chlamydia infection.
Lifestyle Tips
Consistent and correct condom use significantly reduces the risk of chlamydia transmission. Regular STI screening, particularly with new sexual partners, supports early detection and prevents the spread of infection. If diagnosed with chlamydia, complete the full course of prescribed antibiotics and inform recent sexual partners so they can be tested and treated. Avoid sexual contact until treatment is completed and confirmed successful by your healthcare provider.
What It Measures
This test uses PCR technology to detect the genetic material of Neisseria gonorrhoeae in a sample. It can identify the bacterium even when present in very small quantities, making it one of the most sensitive diagnostic methods available. Gonorrhea can infect the genitals, throat, and rectum, and testing may be performed on samples from any of these sites depending on potential exposure.
Lifestyle Tips
Consistent condom use during vaginal, anal, and oral sexual contact significantly reduces the risk of gonorrhea transmission. Regular STI screening is an essential component of sexual health, especially when entering new sexual relationships. If diagnosed, complete the full prescribed treatment regimen and ensure recent sexual partners are notified so they can be tested. Avoid sexual contact until treatment is complete. Be aware that having gonorrhea once does not provide immunity against future infections.
What It Measures
This test detects treponemal antibodies that the immune system produces in direct response to Treponema pallidum. Unlike non-treponemal tests such as the RPR, treponemal antibodies are highly specific to syphilis and rarely produce false positive results. A key characteristic of treponemal tests is that they typically remain positive for life once seroconversion has occurred, even after successful treatment. This means the test indicates whether a person has ever had syphilis, but it cannot distinguish between current and past infection on its own.
Lifestyle Tips
Consistent condom use and limiting the number of sexual partners help reduce syphilis risk. Regular STI screening is a key component of responsible sexual health, particularly for those at higher risk. If you receive a positive result, work closely with your healthcare provider on treatment and follow-up. Inform recent sexual partners so they can be tested. Remember that syphilis is curable with appropriate treatment, and seeking testing is a positive and responsible step.
What It Measures
This test simultaneously screens for two markers: the HIV p24 antigen, which is a viral protein produced early in infection, and antibodies that the immune system generates in response to HIV. By detecting both, the test covers different stages of the infection timeline. The p24 antigen is typically detectable before antibodies develop, which means this combination test can identify HIV infection during the acute phase when viral load is high and transmission risk is greatest.
Lifestyle Tips
Consistent condom use is one of the most effective ways to reduce HIV transmission risk. If you are at higher risk, discuss pre-exposure prophylaxis (PrEP) with your healthcare provider as an additional prevention strategy. Regular HIV testing normalises screening as part of routine health care. Knowing your status empowers you to make informed decisions about your health and the health of your partners. Never share needles or other injection equipment.
Serology
1What It Measures
This test detects the hepatitis B surface antigen, a protein on the outer surface of the hepatitis B virus. HBsAg is one of the first detectable markers after infection and can indicate an acute or chronic infection. The test provides a qualitative result indicating whether the antigen is present in your blood.
Lifestyle Tips
Protect your liver by limiting alcohol intake, maintaining a balanced diet, and exercising regularly. If you have not been vaccinated against hepatitis B, discuss vaccination with your healthcare provider. Avoid sharing needles, razors, or other personal items that may carry blood.
