2. Serum methyl bromide levels
Her absence of pulmonary symptoms makes spirometry or methacholine challenge testing unlikely to produce a positive result. Although there is not diagnostic test for methyl bromide poising, an elevated serum level does document exposure (3). In addition, the predominant symptoms after methyl bromide exposure of headaches, concentration and memory problems, dizziness and nausea, and a reduced ability to do exercise closely resemble our patient’s symptoms (3). Some of the other workers exposed to the shipping containers had similar symptoms.
Her serum methyl bromide level was 1330 mg/L (upper limit of normal 300 mg/L).
