Purpose: To identify the number of dried blood spot specimens that are improperly collected or transported resulting in an additional specimen collected from the newborn to be submitted to the lab, thereby requiring additional work for laboratory personnel to acquire an acceptable specimen.
a) Percent of unacceptable dried blood spot specimens due to improper collection1,2
b) Percent of unacceptable dried blood spot specimens due to improper transport1,2
Screening Data for Denominators: Number of dried blood spot specimens received at your state's newborn screening laboratory.3
- Unacceptable dried blood spot specimens excludes those collected in less than 24 hours [for example Neonatal Intensive Care unit (NICU) infants].
- Definitions for improper collection and improper transport can be found in Appendix A: Glossary of Terms, at the end of the QI Source Document. If it is unknown whether unacceptable specimens were due to either improper collection or transport, they should be counted under improper collection only.
- This includes multiple specimens collected from a single newborn, but not monitoring specimens (e.g. PKU monitoring).
