• A. Statement 1 is true and statement 2 is false
• B. Statement 1 is false and statement 2 is true
• C. Both the statements are false
• D. Both the statements are true

Answer 1

The correct option is A

Statement 1 is true and statement 2 is false

Blood tests measure the concentration of IgE antibodies for a certain allergen in blood. It is used to diagnose allergy. Immunoglobulin E (IgE) is an antibody that is produced by the body's immune system in response to a perceived threat. It is one of five classes of immunoglobulins and is normally present in the blood in very small amounts. Higher the IgE antibody value, greater the chance of allergic symptoms.
