scope:

This standard describes the process and related procedures for collecting diagnostic capillary blood specimens, including capillary blood gases. It is intended for health care professionals responsible for obtaining specimens from patients, as well as for manufacturers of capillary puncture and incision devices and microcollection containers. GP42 also establishes requirements for single-use disposable devices for collecting, processing, and transferring capillary blood specimens, including those for point-of-care testing. This standard does not cover capillary puncture procedures for self-testing, nor does it cover procedures for point-of-care testing.
