Why This Test Is Done

Your healthcare provider may recommend this test if you experience symptoms like sneezing, itchy eyes, runny nose, or skin reactions after spending time in environments with household dust. It can also be used to confirm allergies suspected through other means, such as skin prick tests or patient history.

What to Expect Before the Test

No special preparation is needed. You’ll provide a blood sample, typically drawn from your arm. The test measures IgE antibodies specific to common dust mite allergens in your blood.

What the Test Results Mean

High levels of IgE antibodies to dust mites may indicate an allergic reaction to these allergens. However, results alone do not confirm a diagnosis of allergy; they are often used alongside other tests or clinical findings.

Common Causes of False or Low Results

Results may be affected by recent vaccinations, infections, or medications that suppress the immune system. If you suspect a false result, discuss your full medical history with your provider.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
