|Positive reaction to allergy test|
Your doctor will want to know your signs and symptoms and may want to conduct a physical examination to identify or exclude other medical problems. Your doctor may also recommend one or more skin or blood tests to see if you have an allergy that can be identified. These include:
- Skin prick test. This test uses diluted amounts of common or suspected allergens, such as molds found in the local area. During the test, these substances are applied to the skin in your arm or back with tiny punctures. If you're allergic, you develop a raised bump (hive) at the test location on your skin.
- Blood test. A blood test (sometimes called the radioallergosorbent test, or RAST) can measure your immune system's response to mold by measuring the amount of certain antibodies in your bloodstream, known as immunoglobulin E (IgE) antibodies. A blood sample is sent to a medical laboratory, where it can be tested for evidence of sensitivity to specific types of mold.
