The Widal test is a presumptive (positive) serological test for enteric fever or undulant fever (typhoid fever) if the antigen titer is more than 1:160 and if the person tested had past infections or is immunized. More tests should be done since it is now 1:320. If the next titer comes back 4x higher, then the person has an active case of typhoid fever.
