Computer analysis of allergic histories taken by questionnaire.

We report the development of a detailed allergy questionnaire designed so that the answers can be typed into a mini-computer. Computer programmes have been written to file and to retrieve these answers, and to print a summary which is then 'weighed', so as to produce a clinical atopy score which is then further broken down into indoor and outdoor scores. In a pilot survey of ninety patients, their clinical atopy scores and immunoglobulin E (IgE) profiles have been compared, and additional computer programmes have been written which will (a) assess if a more detailed IgE investigations is warranted, and (b) suggest which allergens, if any, are likely to be responsible for the patients' symptoms.
