Syphilis Tests

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

  • The use of antibiotics before having the test.
  • A blood transfusion in the weeks before having the test.
  • Having other conditions or diseases, such as lupus, liver disease, HIV infection, or a tropical bacterial infection called yaws.

What To Think About

Most states require doctors to report all cases of syphilis to the local health department. In some states, doctors are also required to ask for the names and addresses of your recent sex partners. If you have syphilis, the health department may contact you to make sure that you get treatment. If you give the names of your sex partners to your doctor or the health department, they will be contacted in confidence by the health department and advised to have a test for syphilis.

About results

Syphilis and HIV infection

  • Sores caused by syphilis (chancres) make it easier to get and spread an HIV infection.
  • People with HIV infection who have a negative VDRL test should have a second test for syphilis if the infection is suspected.
