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.
The researchers compared the results of newborn screening tests for 354 infants who died of SIDS with 1,416 infants who did not. ... on a baby’s newborn screening results. For the most part ...
Metascreen, as a newborn metabolic screening test, was first launched by Cordlife in India in October 2013. [1] 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.
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.
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.
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 ]
The following disorders are additional conditions that may be detected by screening. Many are listed as "secondary targets" by the 2005 ACMG report. [1] Some states are now screening for more than 50 congenital conditions. Many of these are rare and unfamiliar to pediatricians and other primary health care professionals. [1] Blood cell disorders
