Abstract
Summary
Tests with chemically different fractions of ragweed pollen have been shown to give varying (or no) degrees of positiveness in cases of hay fever: used as antigens in experimental anaphylaxis, there would seem to be comparatively slight evidence of cross sensitization.
Such results suggest that clinically more satisfactory desensitization might be achieved if the preparations of ragweed used were made to correlate with the results of the tests in the individual case.
