[Diagnosis of allergy in pregnancy].

Occasionally the allergist is required to examine a pregnant woman because of allergic symptoms. For legal and psychological reasons in particular, and not so much for medical reasons, in vivo allergy tests should be avoided during pregnancy. Consideration of the case history, in vitro tests and avoidance of the possible allergen are recommended for diagnosis at such times. In vivo testing is sometimes necessary if the test results will have substantial implications (for the treatment).
