Validation of a Salivary miRNA Diagnostic Test for ASD is a study to find signs (biomarkers) of Autism Spectrum Disorder (ASD) in saliva. ASD is a condition that affects how a person communicates and interacts with others. This study is for children aged 18 months to 6 years and 11 months. A gentle swab will be used to collect saliva, which is not painful or harmful. Parents will also fill out a short questionnaire about their child's health and background. Children who might have ASD, based on their doctor's referral or other signs, can join. Some children will have a follow-up to confirm their diagnosis and talk about any treatments they are receiving.
- Children will have their saliva collected safely.
- This study requires a few visits, including follow-ups.
- Children with certain health problems can't participate.
