The primary goal of this standard is to improve and ensure the quality of blood spots collected from newborns.3 Poor-quality and unsatisfactory specimens place an unnecessary burden on the screening system. Retesting requires additional follow-up, which, if not completed in a timely manner, could result in missed or late diagnosed cases, and can cause unnecessary trauma to the newborn and anxiety to the parents. Because of the complexity and diversity of the specimens that might be encountered and the influence of specimen quality on test results and their interpretation, the specimen criteria and handling procedures should address the common variances.4 Laboratory staff should immediately request another specimen (or the missing information) when the screening laboratory receives a poor-quality specimen (or one missing critical patient information). In all newborn screening (NBS) programs (NSPs), the turnaround time for results is critical if treatments to alter the adverse consequences of a condition (such as irreversible brain damage or death) are to commence in a timely manner.
