Thai device tests for coronavirus in armpit sweat

Scientists have adopted equipment commonly used to detect toxic chemicals in the environment.

For Bangkok market sellers, armpit sweat soaking their T-shirts during the humid monsoon season may contain subtle signs of coronavirus infection, local scientists said.

Thai researchers are developing a sweat-based mobile virus detector and road-tested it this week at a food market owner in Bangkok.

“The samples show that people infected with COVID-19 secrete very different chemicals,” said Chadin Kulsing of Chulalongkorn University in Bangkok.

“Using this discovery, we have developed a device that detects specific odors produced by specific bacteria in the sweat of COVID-19 patients.

Chadin said the tests are 95% accurate and hopes they will be deployed as an affordable alternative to the more expensive swab tests that require laboratory processing.

However, it is still in development and the research behind it has not yet been published or peer-reviewed.

Subject Cotton swab Place a cotton swab in a glass vial under your arm for 15 minutes and sterilize with UV light.

“The technician then uses a suction hose to take the right amount of sample and pressurize it against the analyzer to see the results,” says Chadin.

“this Sweat Testing is more convenient because you get to work while you wait for the results. “

“By PCR test, I have to be in the test center and have to sit down and wait for the results, which only wastes my time. “
