Genetic testing for newborns
WASHINGTON - Good news for the nation's babies: Nearly 90 percent of newborns are getting tested for a host of rare but devastating genetic disorders.As long as this testing can be done through simple bloodwork, I don't have a problem with it. The only fear I have is that procedures like an amniocentesis could become required one day. Amnios don't come without risk, there is a 1 in 200 to 1 in 400 chance of a miscarriage happening. Some would say that's small, but the loss of a child is never small to the parents whose baby died. My wife and I know from personal experience.
Since 2004, specialists have urged that every U.S. newborn be checked for 29 conditions, to detect the few thousand who will need early treatment to avoid death, retardation or other serious problems.
The federal government hasn't issued national screening guidelines, but more states are following the advice on their own. As of June 1, 40 states required testing for more than 20 of those disorders, says a March of Dimes report issued Wednesday.
Topping the list, 13 states plus Washington, D.C., required testing of every newborn for the entire list of 29 conditions, which range from sickle cell anemia and cystic fibrosis to lesser known diseases such as the metabolic disorder LCHAD.
New Hampshire also began testing for all 29 conditions on July 1, after the report's deadline.
The report marks steady progress: Just 38 percent of babies were born in states with intensive screening when the March of Dimes counted in 2005, and 64 percent last year. This year, that number rises to 87.5 percent of newborns, or about 3.6 million babies, the child advocacy group calculated.
Still, almost half a million infants are born in states that require testing for 12 or fewer of the conditions, the analysis found. They include Arkansas, Massachusetts, Nebraska, Oklahoma, Pennsylvania, and Washington. Three more — Kansas, Montana and West Virginia — passed legislation this year requiring checks for all 29 disorders, but that expanded testing hasn't yet begun.
While some states tout testing for even more conditions, the 29 on this "core list" — hearing loss plus 28 genetic diseases that can be diagnosed using a single drop of blood — are those deemed most important for screening by the American College of Medical Genetics.
Lets just hope the nanny state doesn't get any ideas about amnios for all mothers. If they do, you can expect to hear from me on the subject.
