Test Overview
Test Methodology

Real-Time Polymerase Chain Reaction (PCR)/DNA Probe Hybridization

Test Usage

Detection of Enterocytozoon bieneusi and Encephalitozoon species in stool and urine specimens to support the clinical diagnosis of microsporidiosis.

Reference Range *

Negative

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

This test detects DNA from Enterocytozoon bieneusi and Encephalitozoon species and does not detect the less common microsporidia. These 2 genera are the most common causes of intestinal and renal microsporidiosis. While this assay is designed to detect symptomatic infection with Enterocytozoon bieneusi and Encephalitozoon species, it may detect asymptomatic carriage and should only be used for patients with a clinical history and symptoms consistent with microsporidiosis.
