I had a false pos on fta abs test. 1st is active 2nd is weakly active, 3rd is nonactive. Rpr neg. Tppa neg. Does it mean I have lupus? Only sypmtom is burning knee on & off and slight tingling in feet. So scared! If no lupus why the false pos

Probably not. False positive FTA-ABS tests sometimes occur in lupus or other connective tissue or autoimmune disorders. But most people with false positive tests don't have anything wrong;, by itself this does not mean you have lupus or any other health problem. Your symptoms don't suggest lupus. You're being evaluated by a doctor, right? S/He might suggest additional testing. Follow her or his advice.
