Test Overview
Enzyme Immunoassay (EIA)
Detection of presence of shiga toxin 1 and 2.
No shiga toxin detected.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
The limits of detection of SLT-1 and SLT-2 are approximately 7 pg/well and 15 pg/well, respectively. This test detects the presence of shiga toxin of enterohemorrhagic Escherichia coli and Shigella dysenteriae type 1 only. For detection of other enteric pathogens (Salmonella, Shigella, Campylobacter, Aeromonas, Plesiomonas, Yersinia, Vibrio), see "Stool, Aerobic Culture". A positive result does not preclude the presence of other infectious organisms.
