George has been in touch with long-time colleague and friend, Jeanine Walenga, PhD, Loyola University Medical Center. Dr. Walenga collaborates with Dr. Job Harenberg of DOASENSE® in development of the DOAC Dipstick®, a qualitative urine immersion strip that detects a DOAC within ten minutes. A pad for the thrombin inhibitor dabigatran and a pad for Xa inhibitors accompany a pad for creatinine and another for urine color. Dr. Walenga is conducting the first clinical trial in the US.
The DOAC Dipstick, DOASENSE Reader®, and DOASENSE Control® urines received the CE mark in 2019, enabling the company to market in Europe. They are extending to the UK and have plans to market to the US.
