A simple and quick test has been discovered by scientists that uses gold mixed with sugar to tell whether or not you have human flu, or a more serious form such as bird flu.
The method has been developed by experts at the John Innes Centre and the University of East Anglia in Norwich.
The test can detect strains of the flu virus quickly and results are almost instant. Current testing methods can take up to 48 hours for results to come through.
