It does not diagnose, interpret test results, or provide individual health advice. An assessment should be carried out by qualified health professionals who work with children or adults.<\/p> <p>When autism is suspected, families often ask, \u201cWhich test is used?\u201d No single blood test, imaging scan, or online test can diagnose autism on its own. An assessment considers developmental history, the person\u2019s communication and social interaction, patterns of behavior, and professional observation together. The scales and interviews used may vary according to the person\u2019s age, language, developmental level, and needs.<\/p> <h2>First, let\u2019s distinguish screening from diagnosis<\/h2> <ul> <li><strong>Screening:<\/strong> It helps identify whether there may be a developmental concern or a need for a more detailed assessment. It is not a diagnosis on its own.<\/li> <li><strong>Diagnostic assessment:<\/strong> A professional considers the person\u2019s developmental history and clinical observations together, and may use standardised tools when appropriate. The conclusion is not based on a single score.<\/li> <\/ul> <p>A high screening score does not mean that autism is certain. A low score does not invalidate a family\u2019s ongoing concerns either. If there are concerns about a child\u2019s development, it is more appropriate to consult a health professional than to rely on an online score.<\/p> <h2>Assessment tools you may encounter<\/h2> <h3>1. M-CHAT-R\/F: a screening questionnaire for young children<\/h3> <p>M-CHAT-R\/F is a screening tool completed by a parent to help determine whether a young child may need further assessment for autism. Follow-up questions may be used after the initial responses. It is a screening tool; it does not diagnose autism, and the result should be reviewed by a professional. It is not suitable for every age and is not used in adult assessments.<\/p> <h3>2. CARS: a scale that helps organise observations and information<\/h3> <p>CARS (Childhood Autism Rating Scale) is one of the rating tools that may support a professional assessment. Observations and available information about the child\u2019s behaviour, communication, and interaction are considered under specific headings. The Republic of T\u00fcrkiye Ministry of Health\u2019s family guide also mentions CARS as one of the tools that may support the diagnostic process. A scale score alone is not a diagnosis.<\/p> <h3>3. ADOS-2: structured observation<\/h3> <p>ADOS-2 (Autism Diagnostic Observation Schedule) is one of the tools in which a trained practitioner observes a person\u2019s communication, social interaction, and behavioural characteristics during structured activities and interaction. The way it is administered may vary according to age and communication level. It may not be available at every centre, and not using it does not by itself mean that the assessment is incomplete. Results are interpreted alongside other information.<\/p> <h3>4. ADI-R: a developmental history interview with a caregiver<\/h3> <p>ADI-R (Autism Diagnostic Interview\u2013Revised) is one of the tools based on a structured interview with a parent or caregiver about the person\u2019s early development and patterns of behaviour. The family\u2019s observations can help clarify the developmental history. This interview does not diagnose on its own; it is one of the sources that may complement a clinical assessment.<\/p> <h3>5. Assessment of development, language, and everyday living skills<\/h3> <p>A professional may recommend additional assessments to understand the person\u2019s language and communication skills, cognitive development, play, learning, and the kinds of support needed in everyday life. These are not autism-specific \u201cyes\/no\u201d tests. They can help identify the person\u2019s strengths and support needs; an additional developmental or health condition may also need to be assessed.<\/p> <h2>Are blood tests, EEG, or brain imaging performed?<\/h2> <p>There is no blood test, EEG, or brain imaging test that can confirm autism on its own. If a doctor suspects another health condition based on the person\u2019s history and examination, specific tests may be requested. These tests investigate the relevant medical question; they do not replace an autism assessment. The same tests are not expected for everyone.<\/p> <p>A hearing assessment may also be important in some cases, because hearing difficulties can affect communication and language development. Such checks are considered according to the person\u2019s needs and should not be confused with autism screening.<\/p> <h2>How does the assessment process usually proceed?<\/h2> <ol> <li><strong>1. Developmental history is collected:<\/strong> The family is asked for examples of communication, play, social interaction, interests, and everyday life. Previous assessments and observations from educational settings may also be helpful.<\/li> <li><strong>Professional observation is carried out:<\/strong> Communication and behaviour are assessed during the interview and age-appropriate interaction. If needed, additional information is gathered from other settings.<\/li> <li><strong>Appropriate tools are selected:<\/strong> A professional may use screening or assessment tools suited to the person\u2019s age, language, and needs. Not everyone needs to undergo all four of the M-CHAT, CARS, ADOS-2, and ADI-R.<\/li> <li><strong>Information is considered together:<\/strong> A professional reviews the results of the tools alongside the developmental history and observations. A diagnosis is not based on a single test score.<\/li> <li><strong>The findings and support needs are explained:<\/strong> The family or adult is told about the assessment findings, whether further evaluation may be needed, and possible routes to support.<\/li> <\/ol> <p>Referral routes and the tools used in T\u00fcrkiye may vary depending on the health facility and the person\u2019s circumstances. For concerns about a child, families can seek up-to-date guidance from a family physician or a qualified health professional in child and adolescent mental health. An adult assessment is also planned by a professional in a way that suits the person\u2019s age and history.<\/p> <h2>Is \u00c7\u00d6ZGER an autism test?<\/h2> <p>No. The Child Special Needs Report (\u00c7\u00d6ZGER) is not a test for identifying autism; it is a separate reporting process that assesses a child\u2019s special needs and support status. Diagnostic assessment should not be confused with report and service applications. For the scope of \u00c7\u00d6ZGER and application requirements, use current information from the relevant health institutions and official sources.<\/p> <h2>How can families prepare for the appointment?<\/h2> <ul> <li>Note what you have observed, including when and in what settings it occurs.<\/li> <li>Prepare concrete examples of the child\u2019s communication, play, daily routines, and responses to changes.<\/li> <li>Bring previous health, developmental, or educational assessments and information about any support the child receives.<\/li> <li>Ask questions such as, \u201cWhich assessments are planned, what is the purpose of each, and how will the results be interpreted?\u201d<\/li> <li>Do not treat an online screening result as a diagnosis; share the result and your concerns with a professional.<\/li> <\/ul> <h2>Quick answers<\/h2> <h3>Does a positive M-CHAT-R\/F result mean the child definitely has autism?<\/h3> <p>No. This is a screening result that may indicate whether a more detailed assessment is needed. It does not provide a diagnosis.<\/p> <h3>Can a diagnosis be made without ADOS-2 or ADI-R?<\/h3> <p>These tools are not required for every person or in every setting. Diagnosis is based on a qualified professional\u2019s combined assessment of developmental history, observation, and other relevant information; it does not depend on a single tool.<\/p> <h3>Do test scores alone show whether autism is \u201cmild\u201d or \u201csevere\u201d?<\/h3> <p>A single score does not describe all of a person\u2019s characteristics, daily life, or support needs. Results should be interpreted in context by a professional.<\/p> <p>This content is not a substitute for diagnosis, treatment advice, or an individual assessment by a qualified professional.
