| Authority | hl7 |
| Description | References the Observation or DiagnosticReport representing the newborn screening result that originally identified or confirmed the patient's Sickle Cell Disease diagnosis. This extension supports longitudinal care coordination between state newborn screening programs, follow-up programs (such as HRSA-funded SCD newborn screening follow-up programs), and ongoing clinical care. The referenced resource SHOULD be an Observation (hemoglobin fractionation result from newborn heel stick) or a DiagnosticReport representing the complete newborn screen report. |
