What is the most accurate test for syphilis?

Tests used to confirm a syphilis infection include:Enzyme immunoassay (EIA) test.

This blood test checks for syphilis antibodies.

Fluorescent treponemal antibody absorption (FTA-ABS) test.

Treponema pallidum particle agglutination assay (TPPA).

Darkfield microscopy.

Microhemagglutination assay (MHA-TP)..

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.

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.

Can you get a false positive for syphilis?

The RPR test also can produce false-positive results, suggesting you have syphilis when you actually don’t. One reason for a false positive is the presence of another disease that produces antibodies similar to the ones produced during a syphilis infection.
