Researchers from Hong Kong’s PolyU develop diagnostic system to identify up to 40 types of bacteria or viruses causing respiratory infections
- Professor Terence Lau, director of innovation and technology development at PolyU, says the invention can speed up diagnosis for respiratory infections
- A test in the new system is expected to cost a few hundred Hong Kong dollars, while existing tests cost more than HK$1,000 (US$129) for each examination
Researchers from Polytechnic University have developed a system that can identify up to 40 types of bacteria or viruses linked to respiratory infections in around an hour, raising hopes for doctors in speeding up the diagnosis for patients with similar symptoms.
The system, which can detect pathogens including the novel coronavirus, comes as scientists around the world are racing against time to develop tests, treatments, and vaccines against the deadly virus believed to have originated in Wuhan in mainland China.
The project, which was initially denied funding from the Innovation and Technology Commission, also involves the city’s top microbiologist tackling the public health crisis caused by the coronavirus.
Professor Terence Lau Lok-ting, director of innovation and technology development at PolyU who led the research, said the invention could speed up the diagnostic process for respiratory infections.
“In general, current tests can only identify one to three types of bacteria or virus at one time. If you need to check for 40 pathogens, you either get 40 people to perform tests or do the tests 40 times,” Lau said.
He also described the system, which would be able to detect up to 80 types of pathogens at once upon further development, as the “most comprehensive” one.
“Current technologies can cover up to 22 types of pathogens … but more pathogens can cause influenza-like symptoms such as fever, runny nose, and cough,” he said.
