While interpreting the WIDAL test, it is important to know the significant titre. The significant titres are as follow:
H antigen i.e. TH : 1:200
O antigen i.e. TO : 1:100
Paratyphi A flagellar antigen i.e. AH : 1:200
Paratyphi B flagellar antigen i.e. BH : 1:200
Your titres for Salmonella typhi H and O antigens are significant; hence, you have typhoid fever.
