9% respectively and Widal test
was positive in 12 cases giving sensitivity, specificity and PPV of 40.
Forty three out of 70 patients' serum samples sent for rapid screening Widal test
3 Widal Test
Kit ( SPAN) 31 Distel water (5 Litter Packs)
Other investigations like widal test
, blood culture, Australia Antigen (HBsAg) (Positive HBsAg cases were not included) and brucella antibody titre were performed to rule out other causes of fever (1).
In the majority of the group II cases, the Widal test
was positive, suggesting that this test can be a reliable indicator of infection with S.
Results of paired acute- and convalescent-phase serologic testing for dengue immunoglobulin M (IgM) and IgG were negative, as were the microscopic agglutination test for leptospirosis and the Widal test
These 88 cases were proved to be of typhoid by Widal test
and/or blood culture and/or histopathology of the excised margins of the ulcer during exploratory laparotomy.
98 mmol/L, Serum potassium levels, liver function tests, renal function tests, widal test
and blood culture were normal.
Special investigation like Widal test
, ASO titre, throat swab, blood culture, dengue specific IgM antibodies by IgM capture ELISA using DEN antigen, leptospira antibodies by dry dot method using leptospira antigen were carried out, if and when required.
Three sets of blood cultures, sputum cultures, and serologic tests were negative for the following: Chlamydia by microimmunofluorescence, mycoplasma by microparticle agglutination assay, urine Legionella antigen by enzyme-linked immunosorbent assay (ELISA), HIV by ELISA, Burkholderia pseudomallei (melioid) titer by immunohistochemical assay, dengue titer by hemagglutination inhibition using all tour serotypes, Leptospira titer by raicroscopic agglutination test, Widal test
, Weil-Felix test, and viral culture.
