Syphilis TPA Treponema Pallidum Test

The Treponema Pallidum Antibodies (TPA) test is used to help determine if a person has been infected with Syphilis.  This test looks for specific antibodies to the bacteria which causes Syphilis.  It can be used as both an initial screening and a confirmation.  TPA antibodies typically develop 3-4 weeks after infection and persist for the rest of a person's life, even after they have been successfully treated.  Because a TPA test is more specific and sensitive than other types of tests such as the RPR, it has a low incidence of false positives.  The CDC's current recommendation for Syphilis testing is to start with a TPA test.  However, a TPA test cannot distinguish between an active and past infection so positive results are often followed up with an RPR test.  Because an RPR test can sometimes show false positives or cross-react with other illnesses, a TPA test can be used to confirm positive RPR results when someone takes the RPR test first.

Syphilis is a bacterial infection spread through skin to skin contact with an infected area including during sexual contact.  Initial infections are often characterized by the appearance of one or more round, painless sores around the infected area.  Other symptoms can include a rash which often appears on the hands or feet, fever, swollen glands, sore throat, headaches, muscle aches, weight loss, and fatigue.  It is common for Syphilis to go years without displaying any symptoms.  If left untreated, Syphilis can damage the brain, nerves, eyes, liver, and bones. 

Syphilis testing is recommended for anyone who is sexually active at least once a year.  Pregnant women are typically tested for Syphilis due to the risk infection can pose to their infant.  The TPA test can be ordered as a routine screening or when someone has symptoms of Syphilis.  It can also be done as a confirmatory test when someone has previously tested positive for Syphilis.  For a more thorough screening, a Syphilis RPR test can be ordered as well.

Turnaround for this test is typically 2-3 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Incubation Period:

This test is most acurate if it has been at least 3-4 weeks from a potential exposure.
