multiple births adjustment
Special screening protocols and result interpretation for twins, triplets, or higher-order multiple births.
Full Definition
Multiple births adjustment refers to modified newborn screening procedures and interpretive criteria used for twins, triplets, and higher-order multiples, recognizing their increased risk for certain conditions and unique collection challenges. These infants may have different gestational ages, birth weights, and clinical courses despite being born simultaneously, requiring individualized screening approaches and careful tracking to prevent sample mix-ups.
Usage
Usage note: Always specify the number and type of multiples when documenting protocols.
