1) The original research article is open access so you can take a look for yourself. The differences were statistically significant between the two groups (ASD-positive versus -negative) but there isn't enough data to estimate a sensitivity or specificity for using this as a test.
2) It could be a diagnostic test. In theory that would allow potential treatments to begin before the behavioral aspects of ASD manifest (which is around 2yo correct?)
