The Illinois Department of Public Health (IDPH) is rolling out today a test for adrenoleukodystrophy (ALD) for all newborn babies statewide. ALD is a rare hereditary disorder that affects the brain, nervous system, and adrenal gland. It affects approximately 1 in 20,000 births. Early diagnosis of babies with ALD can lead to potentially life-saving interventions, including adrenal steroid replacement and stem cell transplantation. These therapies are only effective during a narrow window, which is often missed. Through universal screening and early diagnosis, treatment options can be evaluated by the baby’s health care providers and initiated in some cases before symptoms develop.The U.S. Department of Health and Human Services added ALD to the national Recommended Uniform Screening Panel in February 2016. Implementing ALD screening required the purchase of new equipment, development of new test methods, Clinical Lab Improvement Amendments lab test validation, and computer system modification to provide laboratory results and facilitate follow up tracking. Illinois is now the 14th state in the U.S. to screen for ALD. Additional information can be found on the dph.illinois.gov website.
