<bot>: HIT hanks for posting your query to Chat Doctor.  Your results are not very significant and doesn't 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.
