FRIDAY, Jan. 17, 2014 (HealthDay News) -- A new test to help
diagnose developmental delays and intellectual disability in
children based on genetic abnormalities has been approved by the
U.S. Food and Drug Administration.
The Affymetrix CytoScan DX Assay scans the entire genetic code
from a blood sample and detects chromosomal variations that can
lead to developmental and learning problems in children, the agency
said Friday in a news release.
Intellectual disability affects as many as 3 percent of children

Analysis of 960 blood specimens found the new test was better at
detecting chromosomal abnormalities that could lead to intellectual
disability than other standard tests, the FDA said.
The new test is produced by Affymetrix Inc., based in Santa
