Newborn Screening Live Blog September is Newborn Screening Awareness Month and this year marks the 50th year since screening programs were put in place. Though few parents are aware of the value of the tests their children have within 48 hours of birth, the Association of Public Health Laboratories estimates that screening programs save more than 12,000 babies a year in the United States. Screening involves a series of blood tests that pinpoint different health disorders that aren't readily apparent but may be harmful or potentially fatal. Although these conditions are considered rare and most babies are given a clean bill of health, early diagnosis and proper treatment can make the difference between lifelong impairment and healthy development. As part of ABC Health's focus on children health this month, we're holding a Twitter chat today at 1 p.m., ET, to help parents and caregivers understand everything they need to know about newborn screening. The chat will be moderated by Dr. Richard Besser, our chief health and medical correspondent. You can join the chat or simply follow along to learn everything you need to know about the process of newborn screening. During the chat you can also follow the live blog below to see Twitter chat highlights and additional information, links and photos.
