Autism screening and diagnosis: what is the difference?

Screening asks a narrower question

A screening tool helps identify who may benefit from a closer evaluation. It is designed for a defined population and purpose. A result is not a diagnosis and should not be stretched beyond the tool's instructions.

Read results safely

Check who the tool is for, who completed it, what time period it covers, and what follow-up its official guidance recommends. Consider real examples and context, not a score alone.

What METAMI does

METAMI explains boundaries and links to official sources. It does not reproduce or score restricted instruments, estimate the probability of autism, or replace professional evaluation.

Limitations

General information cannot answer an individual clinical question.
