Taiwan develops test strips for pesticide poisoning

Taipei, June 23 (CNA) Taiwanese researchers have developed two test strips distinguishing the kind and dosage of pesticide in poisoned patients within several minutes, helping physicians to save lives more swiftly.
Cheng Chao-min, assistant professor in nanoengineering and microsystems at National Tsing Hua University, said Tuesday that the test strips were made for organophosphate and carbamate poisoning, the two most common forms of pesticide poisoning among Taiwanese people.
By dropping the patient's serum on the test strip, physicians at the emergency room and division of clinical toxicology can determine what pesticide the patient had ingested purposely or mistakenly and how much they had taken, based on the resulting color change and shade range, Cheng said.
Compared with the conventional laboratory test, which normally takes 30 to 40 minutes to generate a result, the paper-based testing device is not just low cost but also able to provide the result in a few minutes. And the accuracy is on a par with that of the conventional method, the scholar said.
"The few minutes (of using the test strip) could be the golden life-saving moment," Cheng said.
Cheng was a member of the research team that developed the efficient testing device, which also includes Yen Tsung-hai, director of Linkou Chang Gung Memorial Hospital's department of clinical toxicology.
The research report, titled "Evaluating organophosphate poisoning in human serum with paper," has been publicized online by Talanta, an international journal of pure and applied analytical chemistry. (By Chen Ching-fang and Elizabeth Hsu)
