The purpose of this study is to determine if a simple blood test can help in disease management, particularly asthma. This will be researched by looking at certain features of the blood and to compare asthmatics without allergies to those that have allergy-induced asthma.

Study summary:

A total of 20 participants (men or women) between the ages of 18-50 years with asthma will be enrolled. Participants will remain on their usual asthma treatments as prescribed by their usual asthma care provider. Current asthma treatments and any changes will be recorded at baseline and each subsequent visit. The primary outcome measures are correlation of microvesicle patterns with atopic state and variation from baseline with episodes of poor asthma control. Secondary outcomes include correlations between microvesicle patterns and spirometry, eNO levels, and glucorcorticoid sensitivity.
