Test ID: SHUR    
Schistosoma Exam, Random, Urine

Useful For Suggests clinical disorders or settings where the test may be helpful

Aiding in the diagnosis of schistosomiasis infections involving the urinary tract

Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

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.

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.


If positive, organism identified

Interpretation Provides information to assist in interpretation of the test results

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 Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

No significant cautionary statements
