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
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.
