Typhoid (Widal Test / Typhidot) Test

Why can Widal test results be misleading?

Antibody levels detected by the Widal test can be influenced by prior typhoid vaccination or past infection, sometimes causing a positive result even without current active infection, so results are interpreted alongside symptoms.

Is blood culture better than Widal or Typhidot?

Blood culture is considered the gold standard for definitively diagnosing typhoid fever, since it directly identifies the bacteria, though it takes longer to yield results than antibody-based tests.

When is the best time to test for typhoid?

Testing is generally more reliable after the first week of fever, once antibody levels have had time to rise to detectable levels — very early testing can produce a false negative.
