Ohio State University has issued final reports detailing how test samples were mishandled last year at the university's medical center clinical lab. The incidents eventually led to a settlement with federal health authorities that included the replacement of the medical lab director. The university says in one incident a quality control sample was improperly sent to a laboratory at the Mayo Clinic by a student who had yet to receive full training in lab processes. The university says a misunderstanding about the relationship between university labs also caused samples to be wrongly sent from one lab to another. The incidents cost the university nearly 1 million dollars in legal fees and fines.
