Newborn screening (NBS) is a public health program of screening in infants shortly after birth for conditions that are treatable, but not clinically evident in the newborn period. The goal is to identify infants at risk for these conditions early enough to confirm the diagnosis and provide intervention that will alter the clinical course of the ...
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 ...
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.

The blood of a two-week-old infant is collected for a Phenylketonuria, or PKU, screening. The neonatal heel prick is a blood collection procedure done on newborns. It consists of making a pinprick puncture in one heel of the newborn to collect their blood. This technique is used frequently as the main way to collect blood from neonates.

For the newborn screening, levels of 17α-hydroxyprogesterone (17OHP) are typically measured against predetermined cutoff, which depends on the measurement method. [ 163 ] [ 57 ] While the 17OHP level is easy to measure and sensitive (rarely missing real cases), the test has a poorer specificity, giving high rates of false positives. [ 167 ]
