Before going into details i want to know since how many days do you have fever?If answer is less than 7 days then none of the test done by you are reliable.Only blood culture
can detect typhoid
in first 7 days.
Except typhi h titre of 240 rest of the things are normal.
Fever has many causes but physician can narrow the diagnosis by history and physical examination.
If he is not suspecting typhoid for you means possibility is very less.
If you have already been started on treatement you can continue it as per advise.If still fever persists ,then xou can go for repeat widal
testing to look for rising titre of typhi h.
Hope you got the adequate information.
