Pollen Allergy Testing
Allergists use two tests to diagnose a pollen allergy.
Skin Prick Testing
Skin prick testing involves placing a small drop of the possible allergen on the skin. The nurse will then lightly prick or scratch the spot with a tiny needle through the drop.
If allergic, the site will develop redness, swelling, and itching, usually within 20 minutes.
A wheal might occur instead, which is a raised round area that looks like a hive. Usually, the larger the wheal, the more likely allergic the person is to the allergen.
A positive skin prick test to a particular allergen does not necessarily mean the person has an allergy. Health care providers must compare skin test results with the time and place of a person’s symptoms to see if they match.
Specific Immunoglobulin E (IgE) Blood Testing
These tests are helpful for those with skin conditions or who are taking medicines that interfere with skin testing. Blood testing can be used for children who may not tolerate skin testing. A blood sample is taken and sent to the laboratory. The lab adds the allergen to the blood sample. The lab measures the number of antibodies produced in the blood to attack the allergens.
As with skin testing, a positive blood test to an allergen does not necessarily mean that an allergen caused the symptoms.
Preventing an Allergic Reaction to Pollen Allergy
- Limit outdoor activities when pollen counts are high. This will lessen the amount of pollen allergen inhaled and reduce symptoms.
- Keep windows closed during pollen season and use central air conditioning with allergy-friendly filters.
- Take allergy medicine BEFORE pollen season starts. Most allergy medicines work best this way – by allowing the medicine to prevent the body from releasing histamine and other chemicals that cause allergy symptoms.
- Bathing and shampooing hair daily before going to bed will remove pollen from the hair and skin thus keeping it off bedding.
- Wearing sunglasses and a hat will help keep pollen out of the eyes and off of the hair.
- Limit close contact with pets that spend a lot of time outdoors. Wipe your pets off when they come into the house to remove any pollen off their fur.
- Change and wash clothes worn during outdoor activities.
- Dry clothes in a clothes dryer, not on an outdoor line, to prevent pollen from collecting on the clothes.
