Can syphilis be dormant and test negative?If the result is negative, doctors may ask you to wait a few weeks before returning for another test. This is because the RPR test has the potential for a false-negative result. The same goes for the VDRL test, where false-negative results can be produced if you have had syphilis for less than three months.
Can you have a negative syphilis test and still have it?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 syphilis be detected while dormant?Without treatment in the primary or secondary stages, syphilis progresses to the latent stage, at which time the infection becomes dormant and does not cause symptoms for an extended period of time, up to 20 years. During the latent stage, the infection is still detectable by a blood test, despite the lack of symptoms.
How long can syphilis go dormant?The disease starts as a painless sore — typically on the genitals, rectum or mouth. Syphilis spreads from person to person via skin or mucous membrane contact with these sores. After the initial infection, the syphilis bacteria can remain inactive in the body for decades before becoming active again.
How do you test for dormant syphilis?
Screening tests for syphilis usually include:
- Rapid plasma reagin (RPR), which is a blood test.
- Venereal Disease Research Laboratory (VDRL) test, which can be done on blood or spinal fluid.

How do I know if I have latent syphilis?Persons can receive a diagnosis of early latent syphilis if, during the year preceding the diagnosis, they had a documented seroconversion or a sustained (>2 weeks) fourfold or greater increase in nontreponemal test titers in a previously treated person; unequivocal symptoms of primary or secondary syphilis; or a sex ...
Can you have syphilis antibodies and not have syphilis?If antibodies are found, it is called a reactive test. A reactive or positive test result does not always mean that you have syphilis. Other conditions can cause positive test results. These include injecting illegal drugs, recent vaccinations, endocarditis, and autoimmune diseases.
Can latent syphilis be cured?A single injection of long-acting Benzathine penicillin G can cure the early stages of syphilis. This includes primary, secondary, or early latent syphilis. CDC recommends three doses of long-acting Benzathine penicillin G at weekly intervals for late latent syphilis or latent syphilis of unknown duration.
Can syphilis come back randomly?It is important to avoid sexual contact while going through treatment, as the infection may still be contagious until it is gone. After syphilis treatment, the infection will not flare up or come back. However, it is possible for a person to catch the infection again.
Can you have syphilis for 2 years without knowing?The only way to know is by getting tested. Many men who get syphilis do not have any symptoms for years, yet they remain at risk for health problems if they are not treated. Additionally, the painless sores that show up during the early stages of syphilis often go unrecognized by the person who has them.
How long can you have syphilis before it shows up on a test?It can take up to 12 weeks from the time you're exposed to syphilis for blood tests to show the infection.
How accurate are syphilis blood tests?In sub-study one, the index test demonstrated 96·1% (95%CI=91·7%-98·5%) sensitivity and 84·7% (95%CI=80·15–88·6%) specificity for identification of active syphilis (TPHA positive, RPR positive). It correctly identified 71% (107/150) samples of past-treated syphilis (TPHA positive, RPR negative).
How long does it take for syphilis to show up negative?The majority of patients who have reactive treponemal tests will have reactive tests for the remainder of their lives, regardless of adequate treatment or disease activity. However, 15%–25% of patients treated during the primary stage revert to being serologically nonreactive after 2–3 years (570).
How often is syphilis misdiagnosed?The misdiagnosis rate decreased over the study period (54.2% in 2009 and 41.8% in 2014). Only 27.1% and 24.9% of the correctly diagnosed late neurosyphilis and tertiary syphilis cases received standard treatment, respectively.
What can cause a false negative syphilis test?Your results may be false-negative if the test is done too soon after you are infected with syphilis. It takes 14 to 21 days after infection with the spirochetes for your body's immune response to be found by the test. Drinking alcohol within 24 hours of the test also can give a false-negative result.
How common are false syphilis tests?We found a false positivity rate in total treponemal testing of 0.26%—0.1% in TPPA and 3% in RPR. Our population has a high number of prenatal screens and autoimmune diseases, both of which are more likely to have biological false positives in the RPR screen, a tendency we observed.
Can you have syphilis for 3 years without knowing?In the latent stage of the disease, you have no symptoms, but the disease can be detected by a blood test from your doctor. Syphilis can remain hidden for many years in the latent stage.
Will you always test positive for syphilis after treatment?Note: After successful treatment, a positive nontreponemal test usually becomes negative, whereas the treponemal test usually remains positive for life. *Note: Nontreponemal testing may have a false-negative result during primary syphilis in the very early stages or tertiary syphilis in the very late stages.
Can syphilis show up 30 years later?The main manifestations of tertiary syphilis are neurological disease (neurosyphilis), cardiovascular disease (cardiosyphilis) and granuloma (gummatous lesions or gumma). Tertiary syphilis can affect any organ system up to 30 years or more after infection and can be life- threatening.
Is latent syphilis still contagious?Late latent syphilis is ordinarily not infectious, except for pregnant women, who can transmit infection to the fetus after many years.
Is late latent syphilis contagious?Late Latent Syphilis: Characterized by the absence of symptoms and signs. Categorized as early (≤ 1 year duration) or late (> 1 year duration). Late latent syphilis is generally less communicable through sexual contact. However, this can result in maternal-fetal transmission.
Does syphilis ever go away completely?Is there a cure for syphilis? Yes, syphilis is curable with the right antibiotics from your healthcare provider. However, treatment might not undo any damage the infection can cause.
What is the most accurate test for syphilis?The SpiroTek syphilis test has the highest sensitivity of all treponemal tests (especially in untreated primary syphilis) and is recommended as a confirmatory test by the CDC (1).
Is syphilis commonly misdiagnosed?Rates of syphilis and other sexually transmitted infections are on the rise in the United States. The lesions of early syphilis can be mistaken for those of other infections and conditions, and syphilis should be suspected in all sexually active patients presenting with a new skin rash or an oral or genital lesion.
Can syphilis be undetectable in blood?Shortly after infection occurs, the body produces syphilis antibodies that can be detected by a blood test. Even after full treatment, antibodies to syphilis remain in the blood and may be detectable for many years after the infection has gone.
