CLSI Publishes New Edition of GP42—Collection of Capillary Blood Specimens, 7th Edition



USAThe Clinical and Laboratory Standards Institute (CLSI) has published GP42—Collection of Capillary Blood Specimens, 7th Edition. GP42 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.

This standard also discusses:

  • Precollection requirements.
  • Patient assessment and positioning.
  • Specimen collection and labeling.

Nancy Glasgow-Roberts, PBT(ASCP), Chairholder of GP42, said, “GP42 was written to help instill the confidence and expertise needed to obtain suitable capillary blood specimens the first time around. The difference between good and great in capillary collections is in the details. The GP42 document development committee was committed to these details. Every health care provider collecting capillary specimens can firmly rely on the information in GP42, and laboratories can implement the information in GP42 into their standard operating procedures with confidence.”
