She is board certified by the American Board of Clinical Chemistry. Dr. Slev’s research interests are in immunogenetics and pathogen interactions, particularly HIV and viral hepatitis.


After this presentation, participants will be able to:

  • Understand the importance of newborn screening for SCID.
  • Explain why quantifying T-cell receptor excision circles (TREC) is utilized to detect newborns with SCID.
  • Describe quantitative real-time PCR assay for TREC.
  • Describe current status of newborn screening for SCID.
