Can you get a false negative syphilis test?
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..
Does syphilis always show up in blood test?
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.
What does a syphilis bump look like?

How accurate are syphilis tests?
Results. The sensitivity, specificity, negative predictive value and positive predictive values of the POC syphilis test were: 91.8% (95% confidence intervals 88.4% to 94.5%), 98.5% (98.2% to 98.8%), 71.0% (66.6% to 75.2%), and 99.7% (99.5% to 99.8%), respectively.
How common is a false negative syphilis test?
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.
