Abstract

Clinical and Laboratory Standards Institute standard GP42—Collection of Capillary Blood Specimens provides procedures for collection of capillary blood specimens that contribute to the accuracy of the results and the safety of the patient and the health care professional. Specifications for collection sites, puncture depth, and disposable devices used to collect, process, and transfer capillary blood specimens are also included.

Overview of Changes

This standard replaces the previous edition of the approved standard, GP42-A6, published in 2008. Several changes were made in this edition. One of the principal changes is content reorganization to reflect a process composed of multiple procedures, consistent with the incorporation of QMS principles into CLSI documents. This standard provides sequential procedures that make up the process of successful, safe capillary blood specimen collections. The quality system essentials (QSEs) are foundational building blocks that function effectively to support the laboratory's path of workflow. Adherence to the QSEs ensures that collection is performed at a higher level of overall quality. Other changes include: 

• Providing greater detail on patient identification, registration, and specimen labeling processes 

• Revising identification of proper puncture sites 

• Expanding patient positioning instructions 

• Updating figures 

• Updating references

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.
