# Dermatophagoides pteronyssinus

> This test measures the amount of specific antibodies in your blood that react to Dermatophagoides pteronyssinus, a common house dust mite. It helps show whether your immune system is sensitive to these mites, which is often the cause of year-round sneezing, stuffy nose, or asthma. This information helps doctors distinguish a dust mite allergy from other environmental triggers like pollen or pet dander. While it detects an immune response, this test cannot predict exactly how severe your allergic symptoms will be in daily life.
