Specimen Collection 3.5 mL SST Serum (Preferred) 4 mL Plain Serum 250 uL Microsample Serum Reference Intervals
Normally no antibodies detected
Serum titres of > 1:16 are regarded as significant. Mean serum titres of patients with current schistosomiasis range between 1:256 and 1:1024.
Test performed twice a week. Analysis time 6 hrs
Diagnostic Use and Interpretation
Schistosomiasis (Bilharziasis) is an infection caused by parasites of the genus 'Schistosoma'. Urinary tract Bilharziasis occurs mainly in Africa, and is caused by S. haematobium .
Intestinal Bilharziasis is caused by S .mansoni which occurs predominantly in Africa, Southwest Asia and Latin America.
Man is the definitive host, and the eggs of S. mansoni are shed in the faeces. Susceptible fresh water snails are the intermediate hosts. The adult Schistosomes may persist in man for decades and cause severe organ lesions.
Due to the similarities of the antigens, antibodies to Schistosoma haematobium and Schistosoma japonicum are also detected.
The sensitivity of this test for the detection of S.mansoni infection is approximately 98%. The sensitivity for detection of other schistosoma species is reduced (approx. 80% for either S.japonicum or S.haematobium).
