Question 3
When performing RAST how would one know if IgE levels are high or low in a given serum?
High and low levels of IgE can be determined by comparing your sample with a chart provided in each RAST kit. Explanation
A generic chart won't help you. Positive and negative controls with known amounts of allergen-specific IgE are necessary to quantitate the levels of IgE in a given serum.
