APHL Comments on ISA 2022

APHL supports inclusion of this data element in the Laboratory class of USCDI V4, because it is the main way laboratories identify related lab data records in their system. For lab reports that are de-identified, for example for public health reporting to federal agencies or for research, this identifier is often the only means to link related results on the same specimen together. It may also be used as a proxy for the patient identifier, which is a CLIA required element in systems, that do not support patient administrative functionality.
