48If there are discrepancies during the autism diagnostic assessment between reported signs or symptoms and the findings of the autism observation in the clinical setting, consider:
  • gathering additional information from other sources and/or
  • carrying out further autism specific observations in different settings, such as the school, nursery, other social setting or at home.
56If there is uncertainty after the autism diagnostic assessment about the diagnosis, consider keeping the child or young person under review, taking into account any new information.
57If any of the following apply after assessment, consider obtaining a second opinion (including referral to a specialised tertiary autism team if necessary):
  • continued uncertainty about the diagnosis
  • disagreement about the diagnosis within the autism team
  • disagreement with parents or carers or, if appropriate, the child or young person, about the diagnosis
  • a lack of local access to particular skills and competencies needed to reach a diagnosis in a child or young person who has a complex coexisting condition, such as a severe sensory or motor impairment or mental health problem
  • a lack of response as expected to any therapeutic interventions provided to the child or young person.
