Schistosoma Exam, Random, Urine
Use
This test aids in the diagnosis of schistosomiasis infections involving the urinary tract. Schistosomiasis is an infection caused by several species of trematodes (flukes) in the genus Schistosoma. The adult worms of Schistosoma haematobium inhabit the venous 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.
Special Instructions
Preferred time of urine collection is between 12 noon and 3 p.m., although a 24-hour urine collection is also acceptable. No preservative should be used in the urine specimen.
Limitations
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. Improper specimen collection and handling can affect the accuracy of the results.
