In vitro determination of IgE antibodies in the diagnosis of atopic allergy.

The reaction of IgE antibodies is important in asthma and hay fever. Their role in skin diseases is more obscure and needs to be studied further. IgE antibodies play a role in contact urticaria and a more doubtful role in the triggering of atopic dermatitis. A well-standardized radioallergosorbent test is a valuable tool in the diagnosis of these diseases. A new test for the detection of atopy is discussed.
