Why to test
New Born screening is performed to identify disorders which can not be detected before delivery. As long as the baby is inside mother's womb all essential nutrient are provided to baby by mother's blood so these deficiencies do not manifest in any form.
When the baby is born, its own metabolism, physiology and immune system has to come into action. This is the time when these disorders start taking shape and start causing permanent damage with passing time.
The sooner we detect these disorders the better the outcomes can be and any serious damage or disability can be prevented even leading to near normal recoveries.
Since these disorders are congenital and most are genetic there is no permanent cure and lifelong treatment is necessary.
Since all children suffering from these disorders appear normal at birth so the only way to find out is New Born Screening. If screening is not performed at birth for a child suffering from disorder the child will soon start showing up symptoms and whatever damage has happened until then would be permanent.
When to test New Born Screening is performed on the second day of birth to seventh day of birth ideally.
In case the baby is born premature the test is performed after seven days of birth unless the doctor decides due to medical reason to test earlier.
All children who are sick at birth or spend time in neonatal intensive care unit should also be tested.
How the test is done
Only a drop of blood is needed for testing for 54 disorders due to latest technology. The heel of the child is pricked and small drops of blood are blotted on a special paper card provided by the lab to the doctor.
The dried blood spot of the baby is sent to the lab for testing.
Use the graphic way of heel prick to show how sample is taken
Core Panel of 8 disorders are tested in state of art Fluorescent methods.
The extended panel of 46 disorders are tested latest and the only clinically installed Ultra Flow Liquid Chromatography Mass Spectrometry (Tandem Mass Spectrometer) in India.
The results are sent to the requesting doctor who then explains the implications to the parents of the child.
