Hello dear
Understand your concern
Widal test cut off value is 1:160.
It means any titre greater than Typhi O, 1: 160 (1:170, 1:180) suggest active typhoid infection.
But in early day of fever (with in 7 days), value like 1:80, 1:100, 1:150, 1:140 suggest suspected typhoid fever. It should be repeat after 1 week of fever.
In this type of case antibody should be started after consulting the doctor.
Proper rest, avoid outside food, maintain hydration and anti pyretic for fever should be advisable.
Hope this will help you
