Dust Mite Allergy IgE Blood Test
The dust mite allergy blood test measures the amount of allergen-specific IgE antibodies in the blood in order to detect an allergy to dust mites.
Dust mites are tiny bugs that belong to the family of spiders. You may have an allergy to them, even though you can't see them. Dust mites flourish in temperatures between 68 and 77 degrees and prefer 70 to 80 percent humidity levels. They are accumulated to the conditions inside homes.
Dust mites feed primarily on the small flakes of skin that are shed every day by individuals. The flakes settle in bedding, carpets, upholstered furniture, plush toys, and dust. These places provide a perfect habitat for dust mites.
For certain people, the body parts and the waste of dust mites are allergens. At low humidity levels or high temperatures, most dust mites die. Yet they leave behind their dead bodies and waste. These can cause allergic reactions to continue to occur. Dust mites will live all year in a warm, humid home. The human immune system shifts into high gear when an individual breathes in the waste products of dust mites, producing antibodies to ordinarily harmless substances. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction. Long-term exposure to dust mite allergens, aside from allergy symptoms, can lead to sinus infections and asthma.
Allergy symptoms vary from one individual to the next ranging from mild to severe reactions. Common symptoms of a dust mite allergy may include:
- sinus pressure
- runny or itchy nose
- itchy, watery, or red eyes
- postnasal drip
- scratchy throat
- itchy skin
- trouble sleeping
- swollen, dark-colored skin beneath the eyes
If an individual has asthma and a dust mite allergy, additional symptoms may be experienced, including:
- difficulty talking
- chest pain or tightness
- wheezing, coughing, or shortness of breath
- difficulty breathing
- severe asthma attack
