New technique can quickly detect fentanyl and other opioids

Testing method can analyze blood samples twice as quickly as other techniques University of Waterloo researchers have developed a new blood testing method that can detect potent opioids much faster than traditional approaches and potentially save lives. The method, the latest effort by Waterloo researchers and entrepreneurs to lead health innovation in Canada, can simultaneously analyze 96 blood samples that could contain opioids such as fentanyl in under three minutes - twice as quickly as other techniques. "The difference between our blood testing method and traditional methods used in laboratories and hospitals is that we can do it faster and reach the same conclusion," said Emir Nazdrajic, a postdoctoral fellow in Waterloo's Department of Chemistry and co-author of a study that details the new technique. "Let's say someone who has overdosed is in the emergency room, and doctors need to quickly determine what they've taken to treat them effectively. The speed of our method can be lifesaving." In 2022, over 70,000 Americans died of overdoses from fentanyl , an opioid that is 50 times more powerful than heroin. About 7,000 people die from fentanyl annually in Canada, nearly one-third of which occurs in British Columbia, which is among the worst rates per capita in North America. When using the Waterloo-designed method, the researchers place a small amount of blood in a 96-well plate with a phosphate buffer.
