Frequently Asked Questions
What if a baby was transfused prior to their newborn screening test?
Screening after a blood transfusion does not rule out the possibility of (including but not limited to) Biotinidase Deficiency, Galactosemia, Hemoglobinopathies, and Lysosomal storage disorders. If there is clinical concern for any of these conditions, additional testing and/or consultation with an appropriate specialist may be warranted. Pre-transfusion screening results, if available, would provide complementary information.
What does an "ACTION REQUIRED" notification mean?
If you received a newborn screen results mailer from the Genetic Disease Screening Program and see a notification that says “ACTION REQUIRED”, it indicates additional information or follow up is required. Unless you have been notified of the presumptive positive result, contact your Area Service Center for instructions.
When will I receive my results?
The CA Newborn Screening Program follow-up staff will contact the baby’s doctor as soon as a screen positive screening result is identified. No action needed (screen negative) newborn screening (NBS) results are usually automatically sent to the baby’s birthing facility, licensed homebirth attendant, and the primary care provider (PCP) of record roughly 15 business days after birth.
