Often an otherwise effective drug does not treat a disease because a specific strain does not respond to that treatment.  For example, there are dozens of anti-tuberculous drugs.  Because tuberculous tests cannot identify the strain, patients can end up trying one drug after another, often over the course of weeks or months before a cure can be found.  Major differentiators of SnapDNA include DNA detection at the specificity level of microbial strain in a field deployable instrument that is expected to enable rapid, strain-specific, low cost, POC testing for tuberculous, pneumonia, and other drug resistant strains that may lead to sepsis.
