New research suggests that determining whether or not a child likely has autism could one day be as simple as spitting in a cup.

By looking at RNA in saliva, researchers say they can identify kids on the spectrum with 85 percent accuracy.

The findings come from a study of 456 children ages 19 months to 6 years from various locations across the country, 238 of whom had autism, 84 with developmental delay and 134 who were typically developing. RNA levels were measured from each child’s saliva sample. Then, researchers used machine-learning algorithms to identify the top RNAs in 372 of the samples, which were validated in the other 84 samples.
