Newborn screening begins within 24 to 48 hours of a child's birth when a few drops of blood are obtained from a heel stick. The three children in the photograph all have an inherited metabolic disorder called glutaric aciduria type I, which occurs when the body is unable to degrade certain amino acids (the building blocks of proteins) completely.
In 1978, CDC established the Newborn Screening Quality Assurance Program (NSQAP) to enhance and maintain the quality of newborn screening tests performed in the United States. The birth of Tayla Cunzenheim in Wisconsin on December 23, 2002, was an early Christmas present for her happy parents, Sheryl and Jim. When parents are told that their baby has a disorder like PKU, they need to know for certain that the tests are accurate. Newborn screening begins with a heel stick that is done within 24-48 hours of a baby's birth.
The amount of paper sent to CDC varies with the size of the production lots; however, thousands of strips of randomly selected paper are tested each year. Each year, NSQAP creates and sends out nearly a million dried blood spot reference specimens.
Obtaining accurate resultsGabriel GeorgeGabriel George was diagnosed with sickle cell disease when he was just three weeks old. When Jill Levy-Fisch's third child, Matthew, was born, she knew something was not quite right. Cutting-edge technology is available now that can test newborns for more diseases than has ever been possible. NSTRI has developed laboratory projects focusing on a variety of disorders, including lysosomal storage disorders (LSD) and severe combined immune deficiency (SCID).
Lysosomal Storage Disorders (LSDs): Encouraging research and developmentJohn, Jack, and Christopher EvanoskyBob and Sonya Evanosky know the benefits of early diagnosis and intervention. When Hurricane Katrina hit New Orleans and the levees were breached, the state's newborn screening laboratory was decimated, and the normal operations of newborn screening, diagnosis, and follow-up were interrupted for several weeks.
The Newborn Screening Saves Lives Act, which was signed into law in 2008, requires the development of a national contingency plan for newborn screening for use by a state, region, or consortia of states in the event of a public health emergency. The establishment and continued refinement of a national contingency plan will help ensure that all babies receive the benefits of newborn screening, even under emergency circumstances. For at least three decades, scientists at CDC have been determining which environmental chemicals people have been exposed to and how much of those chemicals actually gets into their bodies. CDC is combining its biomonitoring expertise with its newborn screening expertise to examine the possibility of using newborn screening dried blood spots to measure exposure to environmental chemicals, such as pesticides and metals. Although this is a promising area of study, a number of significant issues need to be addressed before any kind of widespread use can begin. CDC can use its laboratory and newborn screening expertise to collaborate with states and other research partners to develop laboratory methods that can take the microliter volume of whole blood available in dried blood spots and still produce precise, accurate measurements of selected environmental chemicals.
CDC strives to stay in the forefront of technological and scientific advancement in order to continually improve its newborn screening-related activities. The newly expanded laboratory has focused on cystic fibrosis, a particularly complex disease with more than 1500 known mutations. As genetic tests become more available, many newborn screening laboratories are considering the use of DNA-based testing to confirm positive results for disorders such as galactosemia, congenital adrenal hyperplasia, severe combined immune deficiency, and lysosomal storage disorders.
Although DNA-based testing is a developing part of newborn screening, biochemical testing is widely used in state newborn screening programs.
Ultimately, the knowledge gained from future research and collaborations will lead to improvements and expansion of newborn screening activities that save lives and improve the health and wellbeing of all babies. Sweetman L, Millington DS, Therrell BL, Hannon H, Popovich B, Watson MS, Mann MY, Lloyd-Puryear MA, Van Dyck PC.

Excessive levels of organic acids accumulate in the brain and cause degeneration in a region of the brain that controls movement (2).
NSQAPa€”housed in CDC's Environmental Health Laboratorya€”has grown to become the only comprehensive program in the world devoted to quality assurance of newborn screening tests. The number of analytes and the number of disorders in newborn screening tests are not identical numbers. CDC's goal is to include primary analytes for the 53 disorders that can be screened using dried blood spots in NSQAP so that it can help the state newborn screening programs meet the ACMG recommendations with confidence and accuracy. One of NSQAP's most important partners is the Association of Public Health Laboratories (APHL) ,which serves as a dynamic interface between CDC and local, state, and territorial public health laboratories.
Shortly after they brought Tayla home on Christmas Day, they received a call from the hospital telling them that Tayla's newborn screening test showed that she had a congenital disorder. NSQAP works with all state public health laboratories, including the Wisconsin State Laboratory of Hygiene that analyzed Tayla's test, to assure that all test results are accurate and that no disorders are missed.
A health-care professional collects blood from the baby's heel onto a filter-paper card, which is the blood-collection device. The filter paper needs to adhere to strict specifications so that the blood can be collected and analyzed correctly.NSQAP provides quality assurance products, including training, consultation, proficiency testing, guidelines, and reference materials, to state public health laboratories and other laboratories responsible for newborn screening.

NSQAP prepares panels of dried blood spot specimens and sends them out to participating labs.The laboratories analyze the specimens and return their assessments to NSQAP for review. CDC is working to harness the latest advances in science and technology so that more disorders can be detected accurately and treated quickly. In 2008, CDC supported three pilot studies for SCID, including one involving the Indian Health Service and the Western Navajo Reservation in Arizona. As a newborn, LeA ate and slept like all other newborns and began to notice the world around her.
Both of their twin boys, John and Christopher, were premature babies when they were born in 2001, and so it was not surprising to their parents that they met growth and development milestones more slowly than their peers.
One of the lessons learned from that experience is that a back-up system or contingency plan is essential to keep this critical service functioning without interruption.
The benefit of using dried blood spots is that researchers will be able to determine which environmental chemicals are actually in newborns.
Recently CDC expanded laboratory capabilities for its Newborn Screening Quality Assurance Program (NSQAP) by including a group of its scientists (molecular biologists) who have extensive expertise in understanding how genetics and changes in DNA are associated with important public health issues such as diabetes, kidney disease, birth defects, and asthma. The collaboration of CDC scientists and the Cystic Fibrosis Foundation (which was instrumental in providing donor case samples) resulted in the development of proficiency testing materials that are now being used by state laboratories to assure high-quality DNA-based confirmatory testing of positive screening results. As states move testing in this direction, it will be critical for them to have access to technical expertise as well as the kind of blood spot materials necessary for quality assurance and proficiency testing. CDC can use its expertise in both genetics and biochemistry to collaborate with states, research partners, and stakeholders to provide comprehensive data for new methods, new applications, and new blood spot materials for use in newborn screening. CDC scientists will collaborate on population studies with research partners at the federal and state level.
This technology is appealing to the field of newborn screening because, with additional research and development, it holds the potential to screen simultaneously for hundreds of disorders, improve testing specificity, improve prediction of disease severity (which can guide treatment decisions), enable the inclusion of infectious agents, reduce the amount of blood needed for testing, and produce faster results (10). Treatment of lysosomal storage disorders: increased awareness and diagnosis are important as treatment is now feasible.

Blood collection on filter paper for newborn screening programs: approved standard-fifth edition. The spots are analyzed by several different laboratory methods to test for biochemical and genetic markers that reveal hidden congenital (present at birth) disorders. In the past, children with brain damage, like the boy in the picture, were often said to have cerebral palsy.
The newborn screening tests conducted in laboratories look for analytes that are associated with disorders. In many cases, newborn screening makes the difference between life and death for newborns; in other instances, identifying babies with a disorder means that they can be treated and thus not face life-long disability or cognitive impairment. The Cunzenheims worked with a dietician from the Waisman Center at the University of Wisconsin to develop this diet plan. This card is sent to a newborn screening laboratory for testing.Working with manufacturers, NSQAP tests all of the filter paper used in the blood-collection devices before they are released for sale.
Healthy red blood cells are round, and they move through small blood vessels to carry oxygen to all parts of the body. In 2005,CDC established the Newborn Screening Translation Research Initiative (NSTRI) with the CDC Foundation. By 2018, CDC anticipates that it will collaborate on, support, or fund 15 pilot projects for conditions such as Pompe disease, Krabbe disease, Fabry disease, Niemann-Pick, metachromatic leukodystrophy (MLD), DiGeorges disease, and X-linked adrenoleukodystrophy (X-ALD). His life was filled with normal, happy times, but was frequently disrupted with sudden high fevers, bronchitis, sinusitis and other infections that led to extended periods on medication and lengthy hospital stays. Such research will improve pediatric studies, for example, that currently depend on interviews and memory to try and reconstruct exposure history(9).
As newborn screening laboratory testing evolves, CDC will continue to provide the technical expertise and the materials required as more disorders are added to the states' screening panels. If these disorders are not detected and treated soon after birth, they may cause mental retardation, severe illness, or premature death. If such markers are found, the newborn screening follow-up program notifies the parents and physicians so that the baby can receive immediate attention. He was born in a hospital where newborn screening for glutaric aciduria was not being done.
1 and 2) to the program and continues to expand the program.a€  NSQAP provides training, consultation, proficiency testing, guidelines, and reference materials to state public health laboratories and other laboratories responsible for newborn screening in the United States and in several other countries. Some analytes identify more than one disorder, and some disorders are related to more than one analyte. APHL promotes the scientific and technologic expertise of NSQAP to public health officials at the state and federal levels. With PKU, the body cannot process the amino acid called phenylalanine (Phe), which is in almost all foods that contain protein. Her parents describe Tayla as a€?smart as a whip.a€? She attends school and loves to draw and color.
In sickle cell disease, the red blood cells become hard and sticky, and consequently clog the blood flow in small blood vessels. Working with corporate, academic, and Foundation partners,NSTRI assures the quality of research methods during both pilot studies and routine screening. Plans for fun activities were made in spite of the strong possibility that Jeffrey might be too sick to attend. NSQAPa€”the only comprehensive quality assurance program for newborn screeninga€”has the experience, the infrastructure, and the solid reputation in the newborn screening community to respond to the changing technology and rapid expansion of this field.

Genetics and public health in the 21st century: using genetic information to improve health and prevent disease. More than 4million newborns are screened annually in the United States, and thousands of infants are rescued from disability and death. The sisters (not his siblings) on each side of him were tested for glutaric aciduria as part of a regional newborn screening program to develop new methods to diagnose and treat the disorder.
If left untreated, the Phe level can get too high in the blood, resulting in mental retardation(3). This condition can cause pain and other serious problems, such as anemia and infections(4). During the first two and a half years of Matthew's life, Jill went from doctor to doctor searching for an answer in what is sometimes called a medical diagnostic odyssey. Even periods of good health were strained with the ever-present threat of sudden illness caused by Jeffrey's immune deficiency. Early detection and intervention, which included a special diet and intravenous glucose treatments, prevented the sisters from becoming disabled. With APHL's assistance, NSQAP is recognized worldwide and serves as a model program of quality assurance for newborn screening for many other countries.
Matthew endured test after test, and the experience was an emotional strain on everyone in the family. At 10 months, LeA was diagnosed with Krabbe disease, which is part of a group of approximately 40 rare diseases known as lysosomal storage disorders (LSDs). The twins began therapy for cerebral palsy; however, they soon began to lose the ability to walk, their speech worsened, and they were struggling to eat. The different health outcomes for these children and reports about success in identifying and treating glutaric aciduria throughout the United States and Europe have led to widespread screening of newborns for this treatable disorder. At age three-and-a-half, Matthew was finally diagnosed with short chain acyl-CoA dehydrogenase deficiency (SCADD). LSDs are caused by deficient enzymes that normally eliminate unwanted substances in the cells of the body(6).Because the diagnosis took months, LeA was past the period when she could receive treatment. They were considered so rare, that many doctors knew too little about them and had even fewer treatment options.
The twins were eventually diagnosed with metachromatic leukodystrophy (MLD), an LSD.Although there is no cure for MLD, experimental treatment involving bone marrow transplant or cord blood stem cell transplant can delay the progression of the disease in infants without significant symptoms(8). Gabriel was named the 2007-2009 poster child for the Sickle Cell Disease Association of America, Inc. Her physical condition worsened to where she needed feeding tubes, specialty formulas, 36 doses of medicine a day, oxygen, suctioning, and in-house nursing.
John and Christopher were not candidates for treatment because they showed significant symptoms. Some of the symptoms of SCADD include vomiting, low blood sugar, a lack of energy, poor feeding, and failure to gain weight and grow at expected rates. Inspired by Jeffrey's courage and optimism, his parents, Fred and Vicki Modell, started a Foundation to raise awareness about primary immune deficiencies, including severe combined immune deficiency (SCID). The Evanoskys' youngest child Jack tested positive for MLD one month after the twins, and because he showed no symptoms, he underwent a stem cell transplant. Other features of this disorder may include poor muscle tone, seizures, and developmental delays(5). Her mother says that early diagnosis and intervention could have made the difference in LeA's life, and for this reason, Micki Gartzke became a strong advocate for newborn screening. Post-transplant, Jack is doing well, but unfortunately the future for John and Christopher is bleak.The Evanoskys, through their Foundation, are working with CDC to develop newborn screening for MLD.
While there is no standard treatment for SCADD, Matthew has a feeding tube, takes dietary supplements to restore his metabolism, and requires physical therapy.
Without early diagnosis and treatment, babies with SCID usually die within a year of birth.
This collaboration will also establish a dried blood spot card repository for conditions that are part of public health newborn screening programs as well as conditions that may be added in the future.
In addition, CDC has established a program to ensure that the Krabbe test results are accurate. Newborns with SCID do not generally exhibit signs of infection or illness because during the first few weeks after birth, they are protected by the antibodies passed on to them from their mothers and because they have not yet been exposed to infection. This repository will help CDC enhance quality assurance by providing biologic reference materials for current and newly-implemented screening tests.
Spurred to action, Jill began working for the Save Babies Through Screening Foundation, a volunteer organization that supports newborn screening. Illinois has passed legislation mandating newborn screening for Krabbe and four other LSDs (Pompe, Fabry, Niemann-Pick, and Gaucher diseases). Although their children cannot benefit from newborn screening for LSDs, the Evanoskys think that newborn screening is the best way to make sure that other children have a chance at a normal life.
She wants to make sure that no family has to endure a medical diagnostic odyssey like her family did. Before newborn screening for SCID can be implemented at the state level, an effective and efficient screening method (that could process hundreds of samples daily) is needed(7). They recognize that ensuring the accuracy of the tests is critical and believe that families must have the health information they need to make informed decisions. Had Matthew been diagnosed through newborn screening, therapies could have been introduced earlier, and his health outcomes would have been better. With Congressional funding, CDC is addressing this need through cooperative agreements that encourage states to research, develop, and evaluate newborn blood spot screening tests for SCID. While Matthew did not receive the benefit of an accurate, early diagnosis, Jill is thrilled that today her state screens for SCADD and that NSQAP works with her state laboratory to ensure accurate newborn screening tests for SCADD.
