SnapDNA FAQs

TrueRapid means results are available when product is ready to ship. For most food companies, that means a total-time-to-result of one hour or less.

We estimate a total-time-to-result as little as 20 minutes for a standard 90-100mL sample.

Once a contamination occurs, it will often spread to surrounding areas. The largest number of cells are usually at the contamination source and the number of cells decreases as you get further away. Quantitative analysis provides the number of cells at each test site, making it easier, faster and more reliable to identify the contamination source and confirm the efficacy of the remediation process. A non-quantitative test simply reports the presence or absence of pathogen cells. That makes it very challenging to determine the contamination source once it has spread.

Lab tests rely on culturing bacteria in order to grow enough cells for accurate analysis? The culturing process used in lab testing eliminates the potential for quantitative analysis.

Yes. The SnapDNA analysis is designed to meet or exceed lab testing at every metric. This includes analyzing standard industry samples, low false positive rates, live-only cell detection and very low limits of detection.

To minimize false positives, food labs use a 2-stage process of bacteria enrichment followed by RNA/DNA analysis. SnapDNA utilizes a 2-stage process of cell capture/isolation followed by RNA/DNA analysis. Since cell capture/isolation is far more specific than bacteria enrichment, we expect our false positive rate to be the lowest in the industry. Based on 3rd party analysis, we expect our false positive rate to be less than 1 in every 10 million tests.

“Kill” steps such as cooking, pasteurization, or sanitation are designed to kill pathogens, however they don’t destroy the pathogen DNA. Confirming the effectiveness of a kill step or sanitation program requires a food safety test that detects only live bacteria. Live-only analysis is integral in the SnapDNA 2-stage process. Only live cells are capture therefore only live cells are detected. SnapDNA has filed for patent protection on this and other key processes.

The SnapDNA system can be used almost anywhere by almost anyone with minimal training. No special skills are required. Further, the system does not require a lab environment and requires no special facilities modifications.
