Newborn Screening Unit
Georgia Public Health Laboratory
Overview
The Newborn Screening (NBS) Unit of the Georgia Public Health Laboratory analyzes dried blood spot specimens for 28 disorders. Specimens are submitted by hospitals, public and private health clinics, and doctor offices throughout the State. Most of the disorders included in the test panel are relatively rare (incidence = 1:3000 to 1:300,000). However, they are capable of causing mortality or significant morbidity (including delayed development) if not detected prior to the onset of clinical symptoms. Test results are sent to the physician of record. When specimens are submitted by a hospital, a report is also sent to the hospital. Presumptive positive results are reported to the designated follow-up entity, who then notifies the health care provider of the appropriate course of action (e.g., submission of a repeat specimen, confirmatory testing, or clinic visit). Testing algorithms generally involve further analysis of initial abnormal results in order to reduce the number of false positive reports. Depending on the exact testing required, final results are generally available 2-4 working days after receipt of a specimen by the laboratory.
Partners
Newborn screening is more than just a laboratory test. It is a multi-faceted program that includes education, testing, follow-up, medical diagnosis, management, and evaluation. The NBS Unit works closely in partnership with the Georgia Newborn Screening Program to ensure that all infants receive appropriate screening, follow-up, and medical services. More information on newborn screening and the Georgia NBS Program can be obtained at http://health.state.ga.us/programs/nsmscd/overview.asp.
Follow-up of presumptive positive results for metabolic and endocrine disorders is performed by the Emory University School of Medicine, Department of Human Genetics. Follow-up of potential hemoglobin disorders is provided by the Georgia Health Sciences University, Department of Pediatrics and the Georgia Department of Public Health, Newborn Screening Program. The Sickle Cell Foundation of Georgia, Inc. is responsible for follow-up of abnormal hemoglobin results that suggest carrier, or "trait" status.
