***********######################MENINGOCOCCI(5934)########## ENTEROCHECK -- WB IGM RESULT :- NEGATIVE ENTEROCHECK - WB should be used as a screening test in clinically suspected cases only, and its results should confirmed by other supplemental method before taking clinical decisions. In some studies it has been reported that low titre Igm antibodies to S.typhi may persist for about 4 months post infection. Therefore, in endemic area, samples positive yet with low signal intensity should be interpreted with caution, preferably in light of patient history. A negative result, i.e. the absence of detectable Igm antibody does not rule out recent or current infection, as the positivity is influenced by the time elapsed from the onset of fever and immunocompetence of the patient. However, if S.typhi infection is still suspected, obtain a second specimen 5 - 7 days later and repeat the test.
