British scientists have come up with a blood test to diagnose peanut allergies, which offers parents a more efficient way of monitoring the food hazard.
Peanuts are the most common cause of fatal, food-induced anaphylaxis or severe allergic reaction, so it's nothing to brush off.
Ruchi Gupta, lead author of the 2017 study, recommended that after assessing risk with a pediatrician or allergist, parents should introduce their children to peanut products in infancy to prevent potential peanut allergies later in life.
The study, published in the Journal of Allergy and Clinical Immunology, examined 174 children, aged from 6 months to 17 years old and 73 of whom were allergic to peanuts, and found that the worst-affected patients had the most activated mast cells, which contribute to the triggering of allergic symptoms like skin reactions and constricted airways, the BBC reported.
This new blood test, however, promises to change the game for the peanut allergy with 98 percent specificity, researchers from the Medical Research Council (MARC) reported, according to Reuters.
