The first step to limiting the incidence CIN in patients in your cath lab is identifying patients at greatest risk of kidney damage due to contrast. We have developed a pocket CIN-risk calculator. The pocket calculator allows the cardiologist, nurse, or tech to quickly calculate the patient's eGFR and then use the Mehran Risk Score to calculate the patient's risk of developing CIN and requiring dialysis. Please complete the form below to request a complimentary eGFR calculator. Unfortunately we cannot guarantee shipment of calculators, but we will do our best to satisfy all legitimate requests.
