Coag-Sense is now offering a special Professional Testing Promo Kit that includes 5 boxes of Test Strips for $1,209.33. That's a savings of $436! Coag-Sense is on the forefront of coagulation monitoring with its line of PT/INR testing equipment for the home or professional setting. PT/INR Tests by Coag-Sense are primarily used in monitoring the dosing of Coumadin or other warfarin-type blood thinners, the most common drug therapy prescribed to prevent heart disease, stroke, and even cancer. Since heart disease is the number one killer in the United States, Coag-Sense offers a blood testing system using a light based Direct Cloth Detection Technology, which records the coagulation of a blood sample, in kits that provide all the necessary materials.
