The DIY saliva test that tells if you’re catching a cold…– Hmm, could be a fun kit to remake one day!

Scientists have developed a test that predicts how likely you are to catch a cold. They say that by measuring the level of a protein contained in saliva they can provide an advance warning of the risk of infection. In tests over three years on a group of 38 elite America’s Cup yacht racers, the British researchers found that the amount of the bacteria-fighting protein immunoglobulin A – known as IgA – fell significantly shortly before three-quarters of the team fell ill.
