This suggests mild or past exposure to typhoid. 1:160 (H) is borderline positive. Diagnosis must be clinical and lab based.

This is my Widal test report. S. typhi (O) is 1:40. S. typhi (H) is 1:40. S. paratyphi (AH) shows no agglutination. S. paratyphi (BH) shows no agglutination. Remark: Negative Widal test. Is this normal?

Answered by Apollo Doctors

I have been having fever and a little weakness for the past 5 days. I was prescribed medicines for the same. I did a blood checkup today. Urine and hematology reports reveal normal results. But results of WIDAL SLIDE mention S. Typhi 'O' as positive (1:80). Do I have typhoid? I am travelling out of the country in 3 days and need inputs asap.

My blood report shows Typhi O: 1:160 and Typhi H: 1:80, and the lab said I have typhoid. Which medicine should I take?
