Why Doctors Recommend the Widal Test

This means that enteric fevers can show their signs in some individuals gradually. If an individual experiences any signs that indicate typhoid fever, it is recommended to consult a doctor immediately. He/she will suggest a serum  Widal Test to confirm the diagnosis.
