IgG bands	Result	Interpretation
No bands or one to three weak bands or one reactive band or one reactive band together with one weak band.	Negative	No specific antibodies against Treponema pallidum detectable.
One reactive band together with two to three weak bands or four weak bands.	Equivocal	T. pallidum infection is suspected. Check a second sample after 2–3 weeks control.
At least two reactive bands.	Positive	IgG‐antibodies against T. pallidum are detectable. An infection with T. pallidum is very likely.
