Typhoid fever can be diagnosed through several tests, including the Widal Test, Typhi Dot Test, Blood Culture, Stool Culture, and PCR Test. Each test helps detect Salmonella Typhi infection at different stages of the disease. Blood culture is considered the most accurate method for early diagnosis, while antibody-based tests provide quicker results. Choosing the right typhoid test ensures timely treatment and helps prevent complications associated with the infection.
