[|AI|]  Hello, Welcome to Chat Doctor, Widal test is a serological test used in diagnosis of typhoid fever, but it is not a confirmatory test. The typhoid fever should be confirmed by blood investigations and blood culture. As you have tested your sons blood for the tidal test the values of S Ty phi O antigen and S Ty phi H antigen are in normal limits along with the titles of S Paratyphoid. The report suggest that the titles are in normal limits, but it should confirm only by the blood culture. As per the reports he is not having typhoid fever. Thank you.
