Q

What is the definition of an in vitro diagnostic (IVD) medical device, under the IVDD?

A

In vitro diagnostic (IVD), per IVDD:
Any medical device which is a reagent, reagent product, calibrator, control material, kit, instrument, 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
- concerning a congenital abnormality
- to determine the safety and compatibility with potential recipients
- to monitor therapeutic measures

  • The IVDR includes software or system
  • used alone or in combination
  • includes specimen receptacles
  • and also updates the purpose of providing information to include:
    • concerning a physiological or pathological process or state
    • concerning congenital physical or mental impairments
    • concerning the predisposition to a medical condition or disease
    • to determine the safety and compatibility with potential recipients
    • to predict treatment response or reactions

Q

TRUE/FALSE: Assays for research-use only are IVDs.

A

False - these are labeled “research use only” and do not have a clinical application, so they are not medical devices
(no conformity assessment, no CE mark)

A

Home-Brew test, aka in-house developed IVDs: clinical laboratories develop and produce their own reagents
