Specializes in Emergency Medicine

Not Soma (carisoprodol)?: Soma metabolite can trigger bdzp screen, possible Flexeril (cyclobenzaprine hcl) metabolite as well. Need to ask for information on the test used, and method of confirmation / follow-up testing (first usually qualitative, confirmatory quantitative). If no bdzp ingestion, quantitative testing should report negative.
