LABORATORY TESTING OF THE PATIENT WITH MULTIPLE CHEMICAL-SENSITIVITY

Multiple diagnostic laboratory tests are frequently used in the clinic :al evaluation of parsons with multiple chemical sensitivity without a clear a priori hypothesis. In addition, many of these rests are perfo rmed despite a lack oi understanding of the test technical performance characteristics or the clinical significance (test sensitivity and sp ecificity). The result is a plethora of laboratory data that have litt le clinical relevance and that can be both misleading and misused.
