Component-resolved diagnostics (CRD) is a diagnostic approach that utilizes purified native or recombinant allergens to detect the sIgE antibodies response against the individual allergenic molecules. In vitro multiplex allergy test allowing simultaneous measurement of total IgE (tIgE) and Specific IgE detection (Quantitative) against different Allergens - approx 300 molecular components & purified protein extracts based on Microarray technique.
