Additionally, certification upon this same item was extended to versions 2010.01.07 and 2010.02.01 with P2Sentinel v4.2.1 staying the same. These extra certified product variations represent minor product upgrades or marketplace adaptations that didn’t affect the originally tested functionality in version 2007.19.12. ‘CCHIT is pleased to be assessment and certifying products in order that companies can now offer these products to providers who want to purchase and implement certified EHR technology and accomplish meaningful use in time for the 2011-2012 incentives,’ stated Karen M.There are enzymes, salts, and other components that may have an effect on the response of the sensor. With this paper we solved the nagging issue of specificity of our sensing scheme. They did that through the use of dye chemistry to create a trackable marker for glucose. The researchers added microfluidic stations to the chip to introduce two enzymes that respond with glucose in a very specific way. The 1st enzyme, glucose oxidase, reacts with glucose to form a molecule of hydrogen peroxide.
