The testing can be easily performed using capillary (fingerstick) or venous samples. Adding i-STAT PT/INR to your current menu of i-STAT tests may also offer you the opportunity to simplify training and management of operator competency, as well as ordering, and inventory management by requiring fewer platforms to oversee.
