Newborn screening programs initially used screening criteria based largely on criteria established by JMG Wilson and F. Jungner in 1968. [6] Although not specifically about newborn population screening programs, their publication, Principles and practice of screening for disease proposed ten criteria that screening programs should meet before being used as a public health measure.
Metascreen, as a newborn metabolic screening test, was first launched by Cordlife in India in October 2013. Since April 2014, Metascreen became available also in Hong Kong and the Philippines through Cordlife for parents looking for more comprehensive screening of metabolic disorders for their children.
Gas chromatography–mass spectrometry-based technology with an integrated analytics system has now made it possible to test a newborn for over 100 mm genetic metabolic disorders. Because of the multiplicity of conditions, many different diagnostic tests are used for screening. An abnormal result is often followed by a subsequent "definitive ...
The researchers compared the metabolic blood panels from the newborn heel prick tests of 354 infants born between 2005 and 2011 in California who died of SIDS, and compared them with the panels of ...

Phenylketonuria is an inherited genetic disorder. It is caused by mutations in the PAH gene, which can result in inefficient or nonfunctional phenylalanine hydroxylase, an enzyme responsible for the metabolism of excess phenylalanine. This results in the buildup of dietary phenylalanine to potentially toxic levels.
Some may have carnitine deficiency secondary to another metabolic condition or due to maternal carnitine deficiency. Proper follow-up of newborn screening results for low free carnitine includes studies of the mother to determine whether her carnitine deficiency is due to SPCD or secondary to a metabolic disease or diet.

Medical genetics, Dietetics. Maple syrup urine disease (MSUD) is a rare, inherited metabolic disorder that affects the body’s ability to metabolize amino acids due to a deficiency in the activity of the branched-chain alpha-ketoacid dehydrogenase (BCKAD) complex. [3] It particularly affects the metabolism of amino acids- leucine, isoleucine ...
