VeraLight is a privately-held medical device company that was established in 2004 to develop the SCOUT DS® noninvasive screening device for prediabetes and type 2 diabetes. The SCOUT DS is the first noninvasive optical skin test that can replace conventional blood-based diabetes screening. The easy to operate SCOUT DS needs no blood and does not require fasting. The patient simply places a forearm on the portable table-top unit, and a quantitative result is reported in as little as 80 seconds.
