Severe Combined Immunodeficiency (SCID)

(Severe • combined • im-MYOO-noh-di-FISH-uhn-see)

If your baby’s blood spot screening result for SCID is out-of-range, your baby’s healthcare provider will contact you. Together, you will discuss next steps and follow-up plans.

False-positive newborn screening results for this condition do occur. Screening samples collected from babies who were born early (premature) or who are very sick (in the newborn intensive care unit, or NICU) for other reasons can have false-positive results. This screening can also pick up other conditions that affect the immune system.

An out-of-range screening result does not mean that your baby definitely has SCID. It does mean that your baby needs more follow-up testing. Those tests may include blood tests and genetic tests using a blood sample or other sample (collected from the mouth or skin, if needed).

You should complete any recommended follow-up testing as soon as possible. Babies with this condition can have serious health problems in the first few months after birth if they are not diagnosed and treated quickly.
