Maternal levels can be elevated for many reasons, including an open NTD (meningomyelocele, anencephaly, spina bifida), fetal nephrosis, cystic hygroma, fetal GI obstruction, omphalocele, intrauterine growth restriction, multiple fetuses, or fetal demise. Underestimated gestational age can also lead to a misinterpreted test because maternal AFP is higher in earlier pregnancy.
At 3 weeks of age, the average-weight, formula-fed infant should be expected to take: mL
A. 2 to 3 oz, or 60 to 90 mL, every 2 to 3 hours.

C. 3 to 4 oz, or 90 to 118 mL, every 2 to 3 hours.
D. 3 to 4 oz, or 90 to 118 mL, every 3 to 4 hours.
