57713-0

LOINC code 57713-0 identifies "Infant factors that affect newborn screening interpretation". Use this term to record various infant factors (also known as events), including treatments or conditions, that occur prior to collection of the newborn screening (NBS) specimen, and can affect the interpretation of NBS results. Select any answers that apply; you can select more than one answer. If you select "other," use the additional narrative LOINC code for "Other infant factors that affect newborn screening interpretation" to give additional details. Select the answer "Infant in ICU at time of specimen collection" if the infant was in an intensive care unit, neonatal intensive care unit (NICU) or special care baby unit (SCBU). ECMO (extra corporeal membrane oxygenation, aka heart-lung bypass) can affect NBS results for hemoglobinopathies and GALT. Dopamine can affect NBS results for TSH. Steroid treatment can affect NBS results for TSH and 17-OHP. Iodine can affect NBS results for TSH and T4. Antibiotics can affect NBS results for C5. Some anti-seizure medications can affect NBS results for fatty acids. In screening for cystic fibrosis (CF), those babies presenting with meconium ileus or other bowel obstruction often have falsely low IRT's, so some states when they have that information, skip the IRT and go directly to DNA for their screen.
