The test was developed by researchers at the University of Alberta in Edmonton, Alberta, Canada.
Gastroenterologist Dr. Richard Fedorak and colorectal surgeon Dr. Haili Wang developed the urine test technology. The first version of the technology was tested on 1,200 patients and had an accuracy rate of 82 percent. A second version had an accuracy rate of 97 percent.
The test requires a nuclear magnetic resonance machine to detect the metabolites in frozen samples.
