NEW DELHI: An Indian researcher and her team in Canada have developed a new ‘smartphone test’ that can end the agonising wait for lab results by diagnosing bacterial infections, such as a urinary tract infection, in less than an hour. The team is also adapting the technology for detection of viruses, including SARS-CoV-2, by testing it on samples from Covid-19 patients.
The new technology developed by McMaster University uses a tiny handheld device which has a microchip to analyse blood, urine or saliva samples for specific protein signature of an infection. The device which looks like a USB stick plugs into a smartphone to display the result.
Scientists develop hand-held rapid test that can diagnose bacterial infections in less than ONE HOUR
A new test developed by researchers at McMaster University can easily - and accurately - diagnose bacterial infections in under an hour
The test uses a microchip to search patient samples for precise biological material matching an infection
Researchers tried out the test on UTIs and found a sensitivity of 100% and specificity of 78%, meaning it gives few false positives and no false negatives
The test may be a model for other tools identifying diseases from COVID-19 to cancer
