Autism Testing for All Ages

Diagnostic Assessments for Autism Spectrum Disorder (ASD)
Get Started

Autism spectrum disorder (ASD) is a neurodevelopmental condition that affects people of all ages It’s estimated to impact about 1 in 36 individuals in the U.S. (CDC, 2020). While no two people with autism are exactly alike, ASD is typically characterized by core symptoms, including:

  • Difficulties with social communication and interaction
  • Repetitive behaviors
  • Sensory issues

Autism presents differently in every person. Some may have more pronounced challenges in one area and only mild symptoms in another.

It’s also common for people on the spectrum to experience additional mental health conditions or developmental differences, such as:

  • Anxiety and/or obsessive-compulsive disorder (OCD)
  • Attention-deficit/hyperactivity disorder (ADHD)
  • Developmental delays

Because symptoms vary so widely and often overlap with other conditions, ASD can be difficult to identify. At Therapy Lab, our psychologists specialize in diagnosing and supporting people on the spectrum. A comprehensive evaluation is often the first step toward better understanding and symptom management.

What are the symptoms of autism spectrum disorder?

Autism looks different for everyone, but there are a few core areas where symptoms often show up. These can range from mild to more noticeable, and they may vary depending on age, environment, and other factors.
Social Communication and Interaction Difficulties
  • Challenges using and interpreting verbal and nonverbal communication
  • Trouble recognizing social cues or following unspoken rules
  • Struggles with making and keeping friends
Repetitive Behaviors
  • Repetitive movements
  • Insistence on sameness or routine
  • Resistance to change
  • Narrow, often intense, interests or fixations
Sensory Issues
  • Heightened sensitivity to lights, sounds, smells, or textures
  • Picky eating
  • Sensory-seeking behaviors
Research shows that ASD often co-occurs with other disorders, such as anxiety and ADHD, and that there’s significant symptom overlap in these and other conditions, which can make diagnosis more complex.

How is autism diagnosed and treated?

Autism is a behavioral diagnosis—there’s no blood test or medical diagnostic that can identify someone as being on the spectrum. Instead, diagnosis is based on a comprehensive evaluation of behaviors, developmental history, and current functioning. At Therapy Lab, we use a targeted, science-backed approach to provide diagnostic clarity, personalized recommendations, and the documentation you need to move forward. Many people choose this assessment when in need of an IEE or autism diagnosis to obtain school or work accommodations.

ASD isn’t often diagnosed before the age two, even though symptoms can appear in early childhood. In some cases, symptoms may be  overlooked or misinterpreted as typical development, or mistaken for other conditions. For adults, ASD may have been missed in childhood, especially if they developed coping mechanisms or "masking" skills that made their differences harder to spot.

How Diagnostic Assessments Work

We don’t believe in a one-size-fits-all approach to autism testing. Your clinician will complete only the assessments needed to confidently determine whether you or your child meets criteria for an autism diagnosis—no unnecessary testing or added steps.

Our streamlined process enables us to complete assessments faster than traditional providers. Most clients and families receive answers within six weeks, with minimal wait time for appointments.

We also created our assessments with the neurodivergent brain in mind. Every evaluation is tailored to the individual, because no two people are exactly alike. We know that testing can feel stressful, so we make the experience as comfortable and affirming as possible.

What are the benefits of testing for autism spectrum disorder (ASD)?

Understanding ASD and how its symptoms uniquely affect you or your child can provide guidance for securing effective services that help you develop strengths and address challenges

Access accommodations at school or work

A formal ADHD diagnosis can help you or your child qualify for accommodations—like an Individualized Education Plan (IEP) at school or workplace support such as written instructions, quiet workspaces, headphones, or movement breaks.

Understand yourself or your child better

Why do I/they do ____? Why is ____ so challenging for me/them when it seems so easy for everyone else? An autism diagnosis can help explain these differences and offer a clearer path forward.

Recognize long-term effects

When autism goes undiagnosed or untreated, it can increase the risk of developing anxiety, mood disorders, or difficulties in school, work, and relationships. Early identification can help prevent those downstream effects.

Experience greater self-compassion

Understanding more about yourself or your child—and how your experiences may differ from the experiences of neurotypical peers—can lead to more self-acceptance and a stronger sense of identity.

Access accommodations at school or work

A formal diagnosis of ASD can help you or your child qualify for accommodations—like an Individualized Education Plan (IEP) at school or workplace support such as written instructions, quiet workspaces, headphones, or movement breaks.

Determine appropriate treatment or support

We’ll recommend next steps tailored to your needs. These may include individual therapy, social skills groups, support for daily living skills, or, for children, early interventions like Applied Behavior Analysis (ABA) therapy.

What should I expect for the evaluation?

Discovery Appointment

Your evaluation starts with a conversation. In this first appointment, you’ll meet with one of our licensed psychologists who specializes in neurodivergence 

During this appointment, we’ll:

  • Review the results of a few questionnaires you'll have completed before your appointment
  • Talk about your current concerns
  • Confirm that our assessment options align with your goals
  • Plan an individualized evaluation for you or your child

We offer remote assessments for clients in California and Washington, as well as in-person appointments at our Los Angeles office.

Results Appointment

Once testing and information gathering are complete, we’ll schedule a follow-up to walk through the findings and any diagnoses.

This appointment includes:

  • A review of your results
  • A conversation about any diagnoses given
  • Clear guidance on next steps
  • Time to ask questions

We've designed this appointment with different learning styles in mind. We'll go through your testing results, any diagnoses, and next steps using visual aids. 

Prefer a streamlined version? No problem. We’ll provide a condensed report that includes the most essential takeaways: summaries of completed testing, any diagnoses,* and our recommendations.

*We provide formal DSM-5/ICD-11 medical diagnoses that you can share with other health providers, insurance companies, schools, state programs, and any other support services, programs, organizations, or institutions that require documentation.

How long does it take?

Most adults complete about 5 hours of testing over the course of 2 to 3 appointments.

For children and their families, the process typically takes about 6 hours of testing across 2 to 3 appointments.

If your assessment includes third-party questionnaires, please note that it can take up to six weeks to complete this part of the process.

Assessments are available for individuals in California (in person and via video) and Washington (video only).
