Skin prick tests with Obeche wood extract predicts a positive specific challenge with a sensitivity of 74%

Skin prick tests to Obeche (probably from an Abello, Copenhagen extract although this is not completely clear) showed high sensitivity (74%) with a >=3.5 mm wheal. All (34) workers had an immediate reaction on challenge testing. 7 had negative challenges; 1/7 had a positive skin prick test.
