Why newborn screening is important

Wednesday, September 5th, 2018

Newborn screening tests check for rare but serious and mostly treatable conditions. Babies with these conditions often look healthy at birth. If a health condition is found early with newborn screening, it often can be treated. This may help avoid more serious health problems for your baby. Newborn screening includes blood, hearing and heart tests.

When is newborn screening done?

All babies in the United States get newborn screening before they leave the hospital, usually when they are 1 or 2 days old. If your baby is not born in a hospital, talk to her health care provider about getting newborn screening before she is 7 days old. Some states require that babies have newborn screening again, about 2 weeks later.

How is newborn screening done?

Newborn screening has three parts:

  1. Blood test. Your baby’s heel is pricked to get a few drops of blood. The blood is collected on a special paper and sent to a lab for testing. The lab then sends the results back to your baby’s health provider.
  2. Hearing screening. The provider places a tiny, soft speaker in your baby’s ear to check how your baby responds to sound.
  3. Heart screening. This test is called pulse oximetry. It checks the amount of oxygen in your baby’s blood by using a sensor attached to his finger or foot. This test is used to screen babies for a heart condition called critical congenital heart disease (also called CCHD). CCHD is the most severe heart defects. Babies with CCHD need treatment within the first few hours, days or months of life. Without treatment, CCHD can be deadly.

What happens with the tests results?

Most newborn screening results are normal. If your baby’s results are normal, you won’t hear back about them. But you always can ask your baby’s provider for the results.

In rare cases when the screening results aren’t normal, you’ll get a phone call about 2 to 3 weeks after the testing. This call can come from someone at your state’s newborn screening program or from your baby’s health care provider. If you get a call about your baby’s results, don’t panic. Most of the time your baby simply needs more testing.

Your baby’s provider then recommends another kind of test, called a diagnostic test, to see if there is a health problem. If the diagnostic test results are normal, no more testing is needed. If the diagnostic test results are not normal, your provider can guide you about next steps for your baby.

How many health conditions should your baby be screened for?

March of Dimes would like to see all babies in all states screened for at least 34 health conditions. Many of these health conditions can be treated if found early. Each state decides which tests are required. You can find out which conditions your state screens for at babyfirsttest.org.

Newborn screening and the March of Dimes

Tuesday, October 15th, 2013

newborn-screening-picture1This year, the March of Dimes and other health organizations are commemorating the 50th anniversary of newborn screening. In 1959, the March of Dimes began to explore newborn screening (NBS) as a means to detect and prevent the catastrophic consequences of metabolic conditions such as PKU (phenylketonuria) on a large scale. Subsequently, we funded research into several genetic and metabolic diseases that can be tested at birth, expanding the concept of newborn screening as an essential component of maternal/child health care delivery. We have worked tirelessly to promote expanded newborn screening programs in every state and to obtain federal guidelines for newborn screening, which has improved and saved the lives of countless thousands of affected children.

Linus Pauling (1901-1994), winner of the Nobel Prize in Chemistry in 1954, received one of the earliest basic research grants awarded by the March of Dimes. Dr. Pauling proposed the concept of molecular disease, using sickle cell anemia as a model. His finding that sickle hemoglobin differs in a measurable way from normal hemoglobin introduced the idea that heritable changes in the structure of a molecule could lead to improper function and result in disease. Dr. Pauling’s work laid the groundwork for the techniques used in newborn screening and diagnosis of sickle cell anemia.

Robert Guthrie, MD (1916-1995) was a March of Dimes grantee who developed a simple blood test to detect PKU, a cause of brain damage and intellectual disability. Dr. Guthrie refined an earlier PKU test, making it possible to analyze a dried spot of blood on filter paper instead of a liquid blood sample, an easier and inexpensive method that could be used on a mass scale. His breakthrough ushered in an era of state-mandated newborn screening programs. In 1963, Massachusetts became the first state to pass a law making the Guthrie PKU test mandatory, and New York followed soon after. The year 1963 marks the birth of state-mandated newborn screening, whose 50th anniversary we recognize this year.

The March of Dimes went on to award grants to develop inexpensive screening tests for congenital hypothyroidism, congenital adrenal hyperplasia, and biotinidase deficiency. In 1992, we called for every state to establish built-in safeguards for their newborn screening programs so that babies born with potentially catastrophic but treatable metabolic disorders would get help in a timely fashion. In 2000, we proposed a national standard for NBS and applauded an American Academy of Pediatrics review for improvements to the nation’s newborn screening programs, insisting that the primary consideration should be the health of the infant.

In 2008, Congress passed the Newborn Screening Saves Lives Act which established national guidelines on what conditions should be tested in newborn screening programs. The March of Dimes actively advocated in favor of its passage. At present, we promote 31 core conditions for newborn screening based on the U.S. Department of Health and Human Services Secretary’s Advisory Committee on Heritable Disorders in Newborns and Children.
