Syphilis Test

Other names: FTA; TPHA; VDRL; RPR

The test is used to detect the presence of the Trepona pallidum bacterium, which causes syphilis. Syphilis is a sexually transmitted infection, which is spread through unprotected sexual intercourse; in most cases, it can be treated quickly and effectively but it can cause serious effects if left untreated.

When is the test used?

The test is used to detect the presence of a syphilis infection or antibodies to the Trepona pallidum bacterium, which causes syphilis.

The test may be carried out if a patient has symptoms of an infection, including the development of chancres (sores) on the genitals or in the throat; the test may also be carried out if a patient is receiving treatment for another sexually transmitted infection or the patient is pregnant (if left untreated, syphilis can cause serious problems for the developing foetus).

How is the test done?

The test is carried out by taking and analysing a sample of the patient’s blood; the blood is taken from a vein in the patient’s arm (usually on the inside of the elbow) and the sample is then placed in a bottle, labelled with the patient’s name and sent off to the laboratory for analysis.

Other tests, including scraping from a sore on the affected area of the body and a lumbar puncture (for patients who are suspected of having advanced symptoms) may also be carried out.

What do the test results mean?

If the scraping test detects the presence of the syphilis bacterium, this indicates that the patient has an active syphilis infection; the patient will usually be prescribed a course of antibiotics if this is the case.

If the results of the blood test reveal the presence of antibodies to the bacterium, this indicates that the patient has an active infection or they have had an infection in the past.

If a patient gets a positive result, they should advise anyone they have had sexual relations with to get a test; STI tests can be done at GP surgeries, local GUM (genitourinary medicine) clinics and sexual health clinics.
