Performance

Built on more than 5 years of biomedical innovation at Cornell University, VitaScan is the first portable device for rapid and quantitative nutrition testing. The technology is supported by the National Institutes of Health, National Science Foundation, and US Department of Defense and has been validated in human pilot studies.

The VitaScan advantage

Currently, nutritional deficiencies are diagnosed with large laboratory analyzers. Although these instruments are accurate and well-established, they aren’t accessible for many people. VitaScan works in whole blood and can move directly to the patient — get results in 10 minutes, no hospital or trained personnel required.

laboratory level Accuracy

The performance of the VitaScan system has been validated against gold standard laboratory equipment. Although the VitaScan assay is built around low cost disposable test components, our patented image analysis methodology, test design, and biochemical processing enable accurate measurements comparable with larger and more expensive laboratory instrumentation.

disposable test strips

VitaScan tests are designed around low-cost paper strips — just like a home pregnancy test, but for your nutrition. All VitaScan test strips are manufactured in-house.
