QUESTION 3
What is the difference between a RAST and an ELISA?
A) RAST detects IgE, while ELISA detects total IgE
B) RAST detects total IgE, while ELISA detects IgE
C) RAST detects IgG, while ELISA detects IgE
D) RAST detects IgM, while ELISA detects IgG
Answer: RAST detects IgE, while ELISA detects total IgE or specific antibodies.
Rationale: RAST detects IgE antibodies to specific allergens, while ELISA can detect total IgE or specific antibodies to
various antigens.
QUESTION 4
