10-minute saliva test to detect cancer
The âliquid biopsyâ test looks for fragments of genetic material in a tiny drop of saliva.
Early results from lung cancer patients suggest ânear-perfectâ accuracy, according to the scientist whose team developed the system. David Wong of the University of California at Los Angeles said: âWe need less than one drop of saliva and we can turn the test around in 10 minutes. It can be done in a doctorâs office while you wait.
