Clinical Information

Schistosomiasis is an infection caused by several species of trematodes (flukes) in the genus Schistosoma. The adult worms of Schistosoma haematobium inhabit the venus plexus of the bladder and produce eggs that are typically passed in the urine. Peak egg excretion occurs between noon and 3 p.m. Identification of characteristic eggs in urine is diagnostic for infection with this organism.

Interpretation

A positive result indicates the presence of Schistosoma species ova in urine.

 

A negative result does not rule out the presence of Schistosoma species since ova may be present at levels below the detection limits of this assay, or infection may not involve the urinary tract.

Cautions

No significant cautionary statements

Method Description

Filter concentration of urine has been shown to increase recovery of Schistosoma haematobium eggs from urine. Ten milliliters of urine is passed through a membrane filter and the filter is examined under the microscope for the characteristic eggs.(Garcia L: Diagnostic Medical Parasitology. 6th ed.
