Interpretation: Detection of IgE antibodies in serum (Class 1 or greater) indicates an increased<br />

likelihood of allergic disease as opposed to other etiologies and defines the allergens that may be<br />

responsible for eliciting signs and symptoms. The level of IgE antibodies in serum varies directly with the<br />

concentration of IgE antibodies expressed as a class score or kU/L.<br />

Reference Values:<br />

Class IgE kU/L Interpretation<br />

0 Negative<br />

1 0.35-0.69 Equivocal<br />

2 0.70-3.49 Positive<br />

3 3.50-17.4 Positive<br />

4 17.5-49.9 Strongly positive<br />

5 50.0-99.9 Strongly positive<br />

Schistosoma Exam, Urine<br />

Clinical Information: Schistosomiasis is an infection caused by several species of trematodes<br />

(flukes) in the genus Schistosoma. The adult worms of Schistosoma hematobium inhabit the venus plexus<br />

of the bladder and rectum and produce eggs which are typically passed in the urine. Identification of<br />

characteristic eggs in urine is diagnostic for infection with this organism.<br />

Useful For: As an aid in diagnosing schistosomiasis infections involving the urinary tract<br />

Interpretation: A positive result indicates the presence of Schistosoma species ova in urine. A<br />

negative result does not rule out the presence of Schistosoma species since ova may be present at levels<br />

below the detection limits of this assay, or infection may not involve the urinary tract.<br />

Reference Values:<br />

Negative<br />

If positive, organism identified<br />
