Venn diagram indicating (A) the patients in the six groups, (B) the healthy controls and (C) the patients with other febrile diseases are positive with each of the three tests (TPTest, Tubex and Typhidot).

TPTest data point in different groups of study participants.
The TPTest was carried out in different groups of the participants. The cut-off value of the TPTest was 10 ELISA unit. Groups: Group I, blood culture positive; Group II, four-fold change of Widal titre; Group III, Widal titer of ≥320; Group IV, blood culture and Widal test negative; Group V, healthy endemic zone control; Group VI, other febrile disease.
