The customer¿s products have been requested for return.The product has not been received at this time.If the product is returned in the future, a follow-up report will be submitted.Routine retention testing was performed and passed the internal inspection.Retention testing data is reviewed and appropriate actions are taken as needed.Per product labeling, "coaguchek uses human recombinant thromboplastin.Therefore, the comparability to other human recombinant thromboplastins is best, whereas higher deviations can occur with other thromboplastins.However, those higher differences between thromboplastins of different (rabbit, bovine based) origin are not a coaguchek specific issue.Similar differences can be observed when a human recombinant thromboplastin-based laboratory method is compared against several other (rabbit, bovine-based) laboratory methods." this event occurred in (b)(6) unique identifier (udi) #(b)(4).Occupation was lay user/patient.
