House Dust ( Greer Labs ), D Farinae, D Pteronsysinus, Cockroach, Total IgE
The House Dust Allergen Test is an essential tool for understanding and managing allergies, particularly those caused by common household allergens such as dust mites (Dermatophagoides farinae and Dermatophagoides pteronyssinus), cockroach antigens, and other components of house dust. It also measures the total level of IgE antibodies in the blood, which play a significant role in allergic reactions.
House dust is a common culprit of indoor allergies. It is a mixture of many substances, and its composition may vary. Common components include skin cells, fabric fibers, bacteria, and substances like pollen and allergens from dust mites and cockroaches. The proteins found in dust mite waste and cockroach debris are particularly potent allergens for many people.

Frequently Asked Questions
The test involves taking a blood sample from the patient. The sample is then analyzed in the laboratory for the presence of IgE antibodies against the specific allergens.
No special preparation is required for this test.
The results will indicate the levels of specific IgE antibodies in your blood. Elevated levels might indicate an allergy to the respective substances.
Total IgE is the measure of all the IgE antibodies in the blood. This number can be high in individuals with allergies or certain other medical conditions.
If your test results show elevated levels of specific IgE antibodies, it’s important to consult a healthcare provider for guidance and possible treatment or management plans for your allergies.
The test can indicate sensitization to specific allergens but does not directly measure the severity of allergic reactions.
Dust mite allergies can be year-round but may worsen in humid seasons or environments, as dust mites thrive in humidity.
Regular cleaning, using allergen-proof bed covers, and maintaining low humidity in the home can help reduce exposure to house dust allergens.
Yes, this test can be performed on individuals of all ages including children.
There is no cure, but symptoms can be managed with medication and by avoiding exposure to house dust as much as possible.
Yes, an allergy to house dust can develop at any age. It is more common in individuals with a family history of allergies.
Yes, for some individuals, exposure to dust mite allergens can trigger asthma symptoms or even an asthma attack.
While it may not be possible to prevent an allergy, exposure to dust mites and other allergens can be minimized by keeping the home clean, using allergen-proof covers on bedding, and reducing humidity levels.
Generally, the turnaround time for this test is around 5-7 days. However, this can vary depending on the lab.
After the test, your healthcare provider will discuss the results with you. If the test shows you have a house dust allergy, they may refer you to an allergist for further testing and treatment.
It's possible to still have a house dust allergy even if your test results are negative. Some people may react to allergens not included in this test. If your symptoms persist, discuss this with your healthcare provider.
Yes, other tests, such as a skin prick test, may also be used to determine if you have a house dust allergy.
Treatment options for house dust allergies can include over-the-counter or prescription medications to control symptoms, immunotherapy (allergy shots), and lifestyle changes to reduce exposure to house dust.
Yes, it's possible to develop an allergy to other types of dust, such as mold spores, animal dander, or pollen that may also be present in house dust.
Greer Labs is a company that produces a variety of allergy testing materials, including those used for house dust allergen testing.
The test involves a standard blood draw, which may cause a little discomfort and a slight feeling of pressure. However, it's generally well-tolerated by most people.
Specific IgE tests look for antibodies against a particular allergen, like house dust. In contrast, a total IgE test measures the overall level of IgE antibodies in the blood and can be elevated in people with allergies.
