Standardization in the field of in vitro diagnostic medical devices which are reagents, reagent product, calibrators, control materials, kits, instruments, apparatus, equipment, or system, whether used alone or in combination, intended by the manufacturer to be used in vitro for the examination of specimens, including blood and tissue donations, derived from the human body, solely or principally for the purpose of providing information: - concerning a physiological or pathological state or; - concerning a congenital abnormality or; - to determine the safety and compatibility with potential recipients, or; - to monitor therapeutic measures. Specimen receptacles are considered to be in vitro diagnostic medical devices. 'Specimen receptacles' are those devices, whether vacuum-type or not, specifically intended by their manufacturers for the primary containment and preservation of specimens derived from the human body for the purpose of in vitro diagnostic examination. Products for general laboratory use are not in vitro diagnostic medical devices unless such products, in view of their characteristics, are specifically intended by their manufacturer to be used for in vitro diagnostic examination.
