The Widal test is still widely used in diagnosing typhoid fever in developing countries . Often , specific chemotherapy is administered based on a single Widal test . Interpretation of a single Widal test , in turn , depends on the baseline agglutinin titres among the local population in that area . Hence , we aimed to find out the baseline titres in our area . A single blood sample was collected from hospital outpatients with non-infectious diseases , the patients being aged above 18 years and residing in Wayanad district continuously for at least 5 years . The test was performed according to the Widal test kit manufacturer 's instructions and interpreted using standard guidelines . The baseline titre for Anti TO , TH , AH and BH agglutinins in our area was found to be 1 :40 , 1 :80 , 1 :40 and 1 :40 , respectively .
