What testing does and does not do. Laboratory testing on this page is analytical quality control for research materials. A test measures what is in the sample that was sent: its identity, purity, quantity, or a specific contaminant. A certificate of analysis covers only that sample, on that date. It does not establish that a material is safe or effective, it does not approve any product for human or veterinary use, and no product or material referenced here has been evaluated by the Food and Drug Administration. All materials are for in-vitro laboratory research purposes only. Not for human consumption.
