[|AI|]  Dear Friend. Widal is a non-specific test and carries low sensitivity for Typhoid. Since, we can have subclinical infections due to consumption of outside food, so, Tidal test can be high in normal person too. So, what is important is rising titles of Tidal. If titles are rising, means you have typhoid. So, decision to treat would be based on your clinical features and symptoms. Discuss with your doctor. Get Well Soon.
