The US Pharmacopeia---the nation's public standards-setting authority for all prescription and over-the-counter medicines, dietary supplements, and related products---has asked the Institute of Medicine to convene a workshop that will address issues related to their heavy metals testing methodology. The workshop will discuss topics such as the state of knowledge on heavy metals exposure from healthcare products; the health effects of such exposures, USP's and other pharmacopeias' testing methodologies, and goals for any revisions to the methodologies. An unedited verbatim transcript of the workshop will be produced for public dissemination.
