Molecular Technology in Newborn Screening: SCID and Beyond
While molecular technologies have been used to support newborn screening since the 1990s, severe combined immunodeficiency (SCID) is the first molecular test used as the primary screening test in state newborn screening programs. Pioneered by the speaker, state-wide routine SCID screening is based on the detection of T-cell receptor excision circle (TREC) by PCR in dried blood spots. Different cutoff values are established for full term and premature newborns, and abnormal results from the screen are further evaluated by confirmatory tests. The utility of applying next generation sequencing as part of cystic fibrosis screening is also discussed.
Originally presented on October 17, 2013, in Salt Lake City, Utah.
