Blood test may help detect autism in kids

Analyzing the blood sample of a child may help predict if he or she has autism. The test, scientists say, gives accurate results.

The test is the first physical test for autism spectrum disorder, say researchers. They investigated patterns of several molecules and found differences between those of children with ASD and those without.

By measuring 24 molecules from a blood sample, the test can not only tell whether or not an individual is on the autism spectrum, but even the grade.

ASD affects about 1.5% of individuals and is considered as an age-related disability caused by differences in the brain. People with ASD often communicate, interact, behave, and learn in ways that are different from most other people. Research has shown that early intervention can improve development.
