CLSI NBS01 Abstract

Clinical and Laboratory Standards Institute standard NBS01—Dried Blood Spot Specimen Collection for Newborn Screening provides descriptive, stepwise processes and procedures for collecting blood spot specimens for newborn screening. This standard was developed and continues to be updated to promote uniform practices for demographic newborn data and specimen collection. This standard informs and instructs health care professionals who collect and submit dried blood spot specimens on procedures for skin puncture and pain management; application of blood collected by heelstick directly onto the preprinted circles of the filter paper; blood source recommendations and other blood spot specimen collection techniques; filter paper, handling, and mailing package specifications; specimen collection device specifications; handling blood spots collected on filter paper for DNA and/or RNA analysis; and storage and retention of residual specimens. An expanded appendix section provides additional images and descriptions of unacceptable blood spot specimens.
