<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi. I am 22f and I have been down with fever and flu-like symptoms since the past 3 days. I took a blood test today and yielded these results in Widal test:S. typhi H: positive 1160S. paratyphi B-H: positive 1320S. typhi O: positive 180S. paratyphi B-O: positive 180What does this mean?  <response>: Hello, Welcome to Chat Doctor, As you are having symptoms like fever and flu like symptoms for last 3 days for which your doctor has advised to undergo tidal test. The tidal test revealed S. Typhi H - Positive 1:160 and S. Typhi O - 1320 suggest that you are typhoid fever but tidal test is not a confirmatory test for typhoid. If there is a rising titre of tidal it is suggestive of typhoid fever. As tidal test is done after 3 days of fever it should be confirmed by blood culture and this is the best indicator of typhoid fever during the first week of the fever. Thank you.
