FAQs about Autism Testing in 2025
Can online tests diagnose autism?

What’s the best autism test for adults?
For formal diagnosis, ADOS-2 (Module 4) is considered the gold standard. For initial screening, the AQ (Autism Quotient) is widely used and accessible online.
How accurate are autism tests?
Accuracy varies by test. Clinical assessments like ADOS-2 have high sensitivity and specificity when administered by trained professionals. Screening tools are designed to cast a wider net and may produce false positives.

Costs vary widely. Online screening tools are often free. Professional evaluations can range from $1,500 to $5,000, depending on the comprehensiveness and your location. Insurance coverage varies.
