Principle Schistosoma haematobium adult worms are found in the venules of the bladder of infected patients. Eggs work their way through tissues and are released from the body in urine.

Since the eggs may be present in low numbers, the urine is concentrated by centrifugation and the sediment examined microscopically for Schistosoma eggs. Other parasites such as Trichomonas vaginalis and microfilariae may also be detected in urine samples from infected patients.
Container type sterile, screw-capped container
Collection Instructions Collect urine in a sterile, screw-cap container. Peak egg excretion occurs between noon and 3:00 pm in infected patients.
Sample type Urine
Special instructions If an exam for Schistosoma haematobium is desired, collect urine during this time, or during a 24 hour urine collection without preservatives.
Synonyms Schistosoma Haematobium;
Stability Deliver to Microbiology Laboratory (2M33) as soon as possible. Do Not Refrigerate.
