critical sample

A newborn screening specimen that requires immediate processing due to abnormal results or urgent clinical circumstances.

Full Definition

A critical sample designation is applied to newborn screening specimens that have generated results requiring immediate medical attention, typically within 24-48 hours of collection. This classification triggers expedited laboratory processing, immediate result reporting, and urgent clinical follow-up protocols. Critical samples may indicate conditions such as severe combined immunodeficiency, critical congenital heart disease, or severe endocrinopathies that require immediate intervention to prevent serious morbidity or mortality.

Usage

Usage note: Use consistently as 'critical sample' rather than 'critical specimen' for uniformity in newborn screening contexts.
