Experience
of the patient is the most important factor in detection of
allergens. It requires careful observation on the part
of the patient and his family history for the physician to
identify the offending allergens. Regular peak expiratory flow
chart also helps in allergen detection. Systematic evaluation by an allergy/asthma expert helps in
further identification of the incriminating allergens.
However, confirmation can be done by allergy skin prick test
and blood test.
