What is the most accurate test for syphilis?

The direct fluorescent antibody test for T pallidum is easier to perform than dark-field microscopy. It detects antigen and, thus, does not require the presence of motile treponemes. It is the most specific test for the diagnosis of syphilis when lesions are present.

What does a syphilis bump look like?

A syphilis sore (called a chancre) pops up — that sore is where the syphilis infection entered your body. Chancres are usually firm, round, and painless, or sometimes open and wet. There’s often only 1 sore, but you may have more.

Does syphilis pop like a pimple?

The first stage, or primary syphilis, is nearly always characterized by the appearance of a painless sore wherever the spirochete entered the body. The sore, called a chancre, begins as a reddish bump that develops into a pimple. It then opens and ulcerates, often oozing pus until a scab develops.

What is the confirmatory test for syphilis?

Tests to confirm syphilis Tests used to confirm a syphilis infection include: Enzyme immunoassay (EIA) test. This blood test checks for syphilis antibodies. A positive EIA test should be confirmed with either the VDRL or RPR tests.

Can syphilis lay dormant for years?

Latent syphilis If you aren’t treated for syphilis, the disease moves from the secondary stage to the hidden (latent) stage, when you have no symptoms. The latent stage can last for years. Signs and symptoms may never return, or the disease may progress to the third (tertiary) stage.

Can a blood test for syphilis be wrong?

A negative test result is considered normal. However, the body does not always produce antibodies specifically in response to the syphilis bacteria, so the test is not always accurate. False-negatives may occur in people with early- and late-stage syphilis. More testing may be needed before ruling out syphilis.

Can Stage 3 syphilis be cured?

Late stage syphilis can be cured but the damage done to the body is permanent.

Can you get syphilis from kissing?

Second, kissing can also transmit syphilis, which may present as an oral chancre. T pallidum can invade mucous membranes through abrasion. Therefore, oral chancre can result from kissing with a syphilis patient. Therefore, kissing with a syphilis patient should also be avoided in order to block the infection.

How common are false negative syphilis tests?

Since 2000, the number of cases of syphilis in the United States has increased from 2.1 cases per 100,000 to 8.7 cases per 100,000. We report the case of an atypical presentation of secondary syphilis with a false negative rapid plasma reagin (RPR) test, which resulted in delayed diagnosis and treatment.
