Dog Dander Allergy IgE Blood Test
The Dog Dander Allergy Blood Test measures the IgE antibody levels in the blood to detect a dog allergy.
What is the purpose of this test?
Order this Dog Dander Allergy Blood Test to measure the IgE antibody levels in the blood to detect a dog allergy. About 30% of Americans have allergies to pets (dogs or cats), with a dog allergy affecting approximately 5 to 10% of individuals. Dog allergens are easily spread through shedding hair or dander. The dog dander becomes airborne, and once settled, they are hard to get rid of from soft surfaces, such as:
- Bedsheets, pillows, or linens
- Furniture (couches, chairs, or mattresses)
Recent studies have shown that even 90% of American households without pets tested positive for animal allergens. This test may help individuals determine if they have a dog allergy, so they may work with their healthcare provider to develop a management and treatment plan.
What causes an allergy to dogs?
Dog allergies are mainly caused by the dander that becomes airborne and lingers in the air. Once inhaled, the specific proteins in dog dander (skin flakes in animal hair or fur) affect the nasal pathways triggering asthma-like symptoms. Some hypersensitive individuals may also experience an allergic reaction if they come in physical contact with a dog. The key allergens that trigger dog allergies include the following proteins:
- Can f 3
- Can f 1
- Can f 2
- Can f 5
- Can f 4
- Can f 6
When an individual with a dog allergy becomes exposed to these allergens, their immune system recognizes the substances as foreign. As a result, it stimulates the plasma cells to produce specific antibodies that combat the invaders. Suppose the individual is exposed to the dog allergens again through inhalation or direct skin contact. In that case, the immune system "recognizes" the allergen encountered. These antibodies cause a chemical known as histamine to be released, triggering an allergic reaction.
When should I order a Dog Dander Allergy Blood Test?
Individuals may order a Dog Dander Allergy Blood Test if they have experienced symptoms related to a dog allergy. Common signs or symptoms of a dog allergy may include the following:
- Nausea or vomiting
- Itching or hives
- Inflammation of the skin where a dog has scratched, bitten, or licked
- Trouble breathing or wheezing
A severe, possibly life-threatening allergic reaction known as anaphylaxis may occur in some cases. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis may include:
- Rapid or increased pulse
- Swollen throat or lump, making it difficult to breathe
- Low blood pressure
- Extreme dizziness or loss of consciousness
