Newborn screening for metabolic disorders in Spain and worldwide

Newborn screening programs are key players in a country's public health strategies, preventing the burden of care associated with the screened disorders. Its importance has dramatically intensified in recent years due to the increasing number of disorders that fulfil criteria for screening. Since the 1960s, many countries implemented newborn screening programs that are now, at least in developed countries, universal, well established, and with excellent results. Nevertheless, much work is still to be done, mainly in developing countries of Africa, Asia, and South America. In some European countries, including Spain, uniformity of screening panels between different regions is still a challenge, being a source of health inequalities between citizens. The authors will present the current status of newborn screening programs in Spain and integrate it into the current European and world scenario.
