Researchers at the Medical Research Council in Britain have developed a new blood test for peanut allergy diagnosis that is 98 percent accurate, safe and cost-effective. The new test which is five times more cost-efficient than the standard oral food allergy test can also be adapted to test for other food allergies. Peanut allergy is the most common allergy to foods, ahead of milk and shellfish, and has a potentially fatal reaction. <br />
