Tetracore announces successful completion of ricin LFA evaluation
With recent reports of ricin being used to threaten government figures, the DHS opted to perform a comprehensive evaluation of the commercially available LFA for the rapid detection of ricin. The study was intended to ensure the unit used for ricin detection was reliable and provided a rapid response, to keep first response teams safe and minimize the chance of a false alarm.
Dr. David Hodge of the DHS coordinated the study and collaborated with a number of other organizations across multiple locations, including the Centers for Disease Control and Food and Drug Administration Center for Food Safety and Applied Nutrition. The test was conducted in seven phases to thoroughly evaluate the performance of the LFA.
The unit was tested for multiple panels, including repeatability, inclusivity, informational, lectin, near-neighbor, white power and BioWatch filter extract. The panels were extensive to ensure the performance of the unit is what is necessary to comprehensively evaluate the presence of ricin. The test was completed successfully.
"Tetracore respects our on-going collaboration with DHS and will continue to validate our BioThreat Alert LFA products rigorously, so that public health laboratories and first responders have confidence in screening for biological threats," Vice President of Tetracore Tom O'Brien said.
