About the test
Summary of Biomarkers

What does the test result mean?

All Homed-IQ tests come complete with a detailed explanation of the test results and a downloadable laboratory report that can be brought to your GP if needed.

What does a negative test result mean?

A negative test result means that no syphilis was found in the test material you supplied and that no STI treatment is required.

What does a positive test result mean?

A positive test result means that syphilis has been found and that treatment is needed. For your own health and to prevent the spread of STIs, it is important that you receive treatment if you test positive.

In the case of a positive test result, you can take the test results to your own doctor for treatment. You should also warn all your sexual partners to further prevent the spread of STIs. They can then have themselves tested and, if necessary, be treated.

Summary of Biomarkers

What is an STI?

Sexually Transmitted Infections (STIs) are diseases that are transmitted through sexual contact. You can be infected with or pass on a virus or bacteria to someone else during sex. This can be through the penis, vagina, anus, and sometimes also with your mouth or fingers. Many STIs cause little or no symptoms. However, an STI is not harmless, and it can cause uncomfortable symptoms at the location of infection. While most STIs are treatable, if some infections are not treated in time they can cause longer-term damage to the body. It is therefore important that you get tested if you have been at risk to treat the infection and to prevent it from spreading to others.


Syphilis is a bacterial infection spread through sexual contact and is caused by the bacteria Treponema Pallidum. Syphilis can be transmitted through sexual intercourse or oral sex, infecting the penis, vagina, anus, or throat. Syphilis often produces no symptoms, although in the early stages of the infection it may cause a lesion (ulcer or chancre) where the syphilis entered the body. The bacteria infects the mucous membranes of the penis, vagina, anus or mouth and can cause inflammation and rashes. Syphilis can also, without treatment, suddenly make you sick after a period of years without complaints. Serious damage to the brain or heart can then occur. Syphilis can be detected with a blood test. It is easily treated with antibiotics if caught early.

Why do I need to activate my test kit?

Homed-IQ test kits do not have customer names or information on them for privacy reasons. This means in order to link your test to your account, you must activate the test using the unique 12-digit test code before mailing it to the lab. The laboratory cannot process your test results or send them to you unless your test is activated.

What is the difference between incubation period and window period?

The incubation period is sometimes confused with the window period. The incubation period is the time between when an individual is exposed to an infection and when they begin showing symptoms. This is different from the window period, which is the time between when an individual is exposed to an infection and when a test can reliably detect the infection. It is important to consider the window period for each STI when getting tested in order to guarantee the most reliable test results.
