An O antigen titer of 1:160 may indicate typhoid exposure. But Widal is not very specific. If symptoms like fever persist, consult doctor.

Take a CULTURE AND SENSITIVITY - AEROBIC (BLOOD) Test

My brother has typhoid, but the doctor prescribed me Tab Cifran 250, Tab Dolo 650, and Tab Becosules. I feel these tablets may not be proper. Can I take these tablets? My blood report shows Salmonella typhi O: 1:160, Salmonella typhi H: 1:160, Salmonella paratyphi AH: 1:20, and Salmonella paratyphi BH: 1:20. What precautions should be taken?

Answered by Apollo Doctors

My test report shows Salmonella typhi O is 1:160 and Salmonella typhi H is 1:80. Do I have typhoid fever? I have a fever every evening. After treatment, my ESR report is 18. I am 24 years old. I need a helpful answer.
