After Scientists developing an accurate blood test that would monitor allergic reactions better, several children would save themselves from testing positive falsely for peanut allergic reaction.

A test to find out particular antibodies from peanuts that are responsible for fatal allergic reactions was created by researchers at the University of Manchester who worked with Swedish experts.

The test that has just been created was tested at University Hospital of South Manchester. About 1,000 children were given biscuits with or without peanuts. About 80 per cent of children who were thought to have allergies were seen with no reactions. The test reported that several children had hayfever and were allergic to grass or pollen rather than peanuts.

The test that picks up antibodies to the RH2 protein proved that one in 50 children was allergic as compared to the earlier finding of one out of 10 being allergic. This made the test to be 97 per cent accurate.

The test is conducted by measuring levels of antibodies that initiate a reaction to peanuts by rubbing small amounts of peanut on the skin followed by a blood test.

A Sweden-based company called Phadia AB would develop the test.

Prof Adnan Custovic, who led a research, which came out in the Journal of Allergy and Clinical Immunology, said the new test would cut down the number of children diagnosed with peanut allergies.

"Avoiding peanuts is the best way of managing allergic/anaphylactic reactions to peanuts," Custovic said.
