INCORRECT
Question 2
An allergist performs skin testing on a patient because every time he mows his lawn, he gets severe hayfever. The test results are negative for all antigens tested so she decides to do a bermuda grass RAST on the patient. The RAST tells her _________________ .
The patient is taking allergy medication which blocks the wheal and flare reaction. Explanation
The patient may be taking antihistamines, but RAST, even if positive when the skin test is negative, would not directly indicate this.
