How is syphilis tested?
Testing for syphilis involves a blood test. It may take twelve weeks for syphilis to show up in a blood test from the time of infection.
A doctor or nurse may also check your genitals or other parts of your body for sores or rashes. They may do a swab test by taking a sample of fluid from any sores.
You should get a test for syphilis if you are worried you might have it, if you have symptoms, or if a sexual partner has been diagnosed with syphilis. It's important to get tested and treated as soon as possible as untreated syphilis can cause serious problems.
You can get a test for syphilis by going to a sexual health clinic or by ordering a test kit online.
