Test
Schistosoma haematobium
CategoryMicrobiology
Pre-analytical
The sample of choice is a urine sample in a sterile container without boric acid collected between 10am and 2pm (period of maximum activity). It is preferable to obtain total urine collected over the time period between 10am and 2pm as it has been shown that a maximum concentration of eggs is excreted at this time. Alternatively a 24hr collection of terminal samples of urine may be obtained. In patients with haematuria, eggs may be found trapped in the blood and mucus in the terminal portion of the urine specimen. 
If the urine cannot be transported to the laboratory for examination within an hour of collection, it is advisable to add 1mL of undiluted formalin to preserve any eggs that may be present. Collect specimens before antimicrobial therapy where possible.
