<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi sirmadam doctor told me that you have typhoid I don t know how they could identified this sick actually blood check up n some investigation are made and results are salmonella 0 is 1:40 and salmonella H is 1:80 and widal test is negative so how could I know about these results can you explain it sir pls  <response>: HIT hanks for posting your query to Chat Doctor. Your results are not very significant and doesnt indicate with 100 surety that you have Typhoid. Actually a value of 1:160 or more is considered significant. What you can do is, you can get a different test for Typhoid which will give confirmation with 100 surety. The test is called IGM and Egg Ty phi dot test. Hope this information was useful to you. Any clarifications feel free to ask.
