Mold Spores & Allergies

Mold is everywhere, so avoiding allergies can be difficult.

Usually the body reacts without a problem to substances it comes into contact with. When the immune system overreacts, it is called an allergy. Mold spore allergies can develop as avoiding mold is tough (it is everywhere) and mold rarely dies but remains dormant until prime conditions allow it to grow.

Cause

The immune system misinterprets mold spores as enemies to the body. An allergic reaction is the body's response to the perceived threat.

Risk Factors

A family history, being a child, and having other allergies raises a person's risk of developing a mold allergy.

Symptoms

Allergies to mold spores are similar to seasonal allergies with a runny nose, itchy and watery eyes, sneezing, and cough.

Allergy tests

There are two types of tests for allergies to mold. The first is the skin-prick test, where an allergist lightly pricks the skin with substance that may be causing the reaction. If hives appear, the test is positive for that allergen. The second test is a blood test. Blood is drawn and sent to a laboratory to check tolerance levels.

Treatment

Treatments for mold spore allergies include avoidance, over-the-counter medications, prescription medications, and immunotherapy.
