Newswise — The Iowa Maternal Screening Program now provides women across the state access to the most advanced and safest methods to screen for Down syndrome and open neural tube defects with the recent addition of the Iowa Maternal Integrated Screen to the tests performed at the University Hygienic Laboratory.
"The Iowa Maternal Integrated Screen offers the most effective and safe method of screening for women because it uses information from both the first and second trimesters combined into a single risk assessment," said Stan Berberich, Ph.D., University Hygienic Laboratory manager for the maternal and newborn screening programs.
With this method, Berberich explained, the screen-positive rate is significantly lower and provides a better detection rate than either the Iowa Maternal Quad Screen, which uses information from only the second trimester, or the Iowa Maternal First Trimester Screen, which uses information from only the first trimester.
"A lower screen-positive rate reduces the number of women who will be offered a diagnostic test, such as an amniocentesis, which carries a small risk of complications, including miscarriage," Berberich said.
The Hygienic Laboratory is the first state public health laboratory in the nation to provide this important integrated screen, said Christopher Atchison, director of the laboratory.
"Women throughout Iowa can benefit because this screen may reduce the need for other diagnostic tests and their associated risks," Atchison said.
Although the Iowa Maternal Integrated Screen is specifically designed to detect Down syndrome, Trisomy 18 and open neural tube defects, the result sometimes will suggest the possibility of other problems with the pregnancy or the developing baby. It may indicate a risk for delivering the baby early or having a baby with a low birth weight. The screen also may indicate a problem with the placenta or the need for extra medical help before the baby is born or at the time of delivery.
The University Hygienic Laboratory is identified by the Iowa Department of Public Health as the designated laboratory for Iowa's screening programs administered through the department's Center for Congenital and Inherited Disorders. The test was added based on recommendations made by the state's Congenital and Inherited Disorder Advisory Committee.
