fta abs- non reactive
Hi, your question is a bit complicated. You should consult your doctor on this. Your VDRL test is positive if it is weakly reactive and the TppA is reactive but the FTA is non reactive. This could mean that the penicillin shot didn't work and you may still have syphillis. This is because the FTA can be negative during the early and late stages of Syphillus. The best time to take the FTA test is midstage. The TppA test is a confirmatory test for the VDRL screening test. It is used in patients that may be negative for VDRL but have signs and symptoms of late Syphillus. If that is positive you still have Syphillus or were reinfected if you had unprotected sex after the penicillin shot. Once the FTA becomes positive it can remain positive for life, meaning you have antibodies against the Syphillus. So they first screen with a test call RPR or VDRL, if that is positive they do the TppA and .FTA. Hope this makes sense.
VDRL is Veneral Disease Reference Laboratory. It doesn't affect your body is just the name of a test.
