[Description of a method for measuring sera with a high level fo IgE: test through the inactivation of anti-IgE covered phages].
The Fab fragment of an anti-IgE serum was conjugated with the  bacteriophage T4 through the use of glutaraldehyde. The conjugated phage was inactivated by human sera which contained IgE. The degree of inactivation allowed to make a distinction between the sera of normal individuals and that of those in whom it is known that high levels of Ig E exist, as in patients with allergic diseases. The method is quite sensitive, economical and does not require costly equipment. Besides, the conjugated phage is preserved for prolonged periods of time.
