News Health: A new and inexpensive same-day test could help pregnant women learn if their developing fetus has genetic problems that increase their risk of miscarriage.
The Short-read Transpore Rapid Karyotyping (STORK) test can detect extra or missing chromosomes using samples collected from standard prenatal tests like amniocentesis and chorionic villus sampling, a new study found.
A team led by Brynn Levy and Dr. Zev Williams of Columbia University Irving Medical Center compared STORK against standard methods of genetic analysis. They tested 218 samples and found that STORK had an accuracy rate of 98% to 100%.
Researchers touted STORK’s potential usefulness in identifying the genetic causes of miscarriage. Genetic testing is only recommended now if a person has had multiple miscarriages, but an easy and cost-effective test like STORK can be offered after a single miscarriage.
They reported their findings Aug. 18 in the New England Journal of Medicine.
Primary funding for the study came from the U.S. National Institute of Child Health and Human Development, with additional support from the U.S. National Cancer Institute.
