ODACTRA Frequently Asked Questions (FAQs)


How do I know if I have a house dust mite allergy?

Only a health care provider, such as an allergy specialist, can find out for sure if you have a house dust mite allergy. If you have allergy symptoms all year long (sneezing, watery eyes, congestion, or runny nose), there’s a chance it’s from house dust mites.

An allergy specialist can do a skin prick test or blood test to find out if you have a house dust mite allergy.

A skin prick test is when your doctor puts a small amount of house dust mite allergen—the part that causes allergy symptoms—into your skin to see how your skin reacts. A raised bump or red spot (called a hive or wheal) may appear in a few minutes. Your allergy specialist will likely test for other allergies at the same time.

An allergy specialist can also find out if you are allergic to house dust mites through a blood test. It may take a few days to get the results of this kind of blood test.
