RAST Activity

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 allergic to ragweed, not bermuda grass.

Explanation
The RAST was done on bermuda grass, not ragweed and there are certainly more than 2 grasses that cause allergies.
