You’re scrolling through TikTok or Instagram and a video stops you cold. Someone is listing "five signs you might be autistic," and suddenly, your whole life—the way you hate the texture of velvet, your "quirky" obsession with vintage train schedules, the fact that you feel like you're performing a script in every social interaction—starts to click. It’s a heavy moment. You start searching for a test to see if you have autism, hoping for a "yes" or "no" that finally makes sense of the noise.
But here’s the thing.
The internet is flooded with quizzes that promise a diagnosis in three minutes. Most are junk. Real clinical discovery is a messy, nuanced, and often expensive process that doesn't fit into a tidy digital checkbox. Understanding where you land on the spectrum requires moving past the 10-question clickbait and looking at the actual diagnostic tools used by experts like Dr. Tony Attwood or the clinicians at the Sarah Hendrickx neurodiversity specialized practices.
The Reality of Online Screening Tools
Let’s be real: an online quiz isn't a diagnosis. It’s a flashlight in a dark room. Most adults seeking answers start with the Autism-Spectrum Quotient (AQ-10) or the RAADS-R (Ritvo Autism Asperger Diagnostic Scale-Revised).
The RAADS-R is a bit of a legend in the community. It was specifically designed to identify adults who "escape" diagnosis in childhood. It asks about things like sensory sensitivities and social nuances that most people take for granted. If you score high, it doesn't mean you're definitely autistic, but it means your brain processes the world in a way that significantly overlaps with the autistic experience.
The problem? Self-reporting is hard. We all have "masking" behaviors—strategies we’ve developed to appear "normal"—that can skew the results. You might answer "no" to having trouble with eye contact because you’ve forced yourself to do it for twenty years, even though it feels like staring into a sun.

Why a Professional Test to See if You Have Autism is Different
When you sit down with a neuropsychologist, they aren't just looking at your answers. They’re looking at how you answer.
Clinical diagnosis often involves the ADOS-2 (Autism Diagnostic Observation Schedule). It’s less of a test and more of a structured interaction. The clinician might ask you to describe a picture book or perform a simple task. It feels a bit silly, honestly. You’re an adult being asked to play with toys or tell a story, but they are observing your use of gesture, your eye modulation, and how you flow through a conversation.
They also look at your developmental history. This is where it gets tricky for adults. If your parents aren't around or don't remember your toddler years, clinicians use the ADIR (Autism Diagnostic Interview-Revised), which focuses on early childhood behaviors. Did you line up your cars instead of racing them? Did you have intense meltdowns over the sound of the vacuum?
The "Female Phenotype" and the Failure of Traditional Testing
For a long time, the medical world thought autism was a "boy thing."
Because of this, the standard test to see if you have autism was calibrated for little boys who liked spinning wheels. Women, non-binary individuals, and people of color often present differently. They might be highly social but find it exhausting. They might have special interests that are socially "acceptable," like Taylor Swift or makeup, but the intensity of that interest is what marks it as autistic.

Dr. Devon Price, author of Unmasking Autism, points out that many people spend decades "performing" neurotypicality. This masking is so effective that even a trained professional might miss the signs unless they specifically look for the internal cost of that performance. If you're a woman seeking a diagnosis, you need a clinician who understands that "quiet and polite" doesn't mean "not autistic."
What Most People Get Wrong About the Spectrum
People hear "spectrum" and think of a line from "not autistic" to "very autistic."
That's wrong.
Think of it more like a color wheel or a graphic equalizer on a stereo. You might have "maxed out" sensory sensitivities but "low" support needs in communication. Or you might be non-verbal but have zero issues with motor skills. This is why a single test to see if you have autism can feel so reductive. It’s trying to map a 3D landscape onto a 1D piece of paper.
The Financial and Emotional Hurdle
Getting an official piece of paper is expensive. In the U.S. or the UK, private assessments can run anywhere from $1,500 to $5,000.

Waitlists for the NHS or insurance-covered providers can be years long. This brings up a massive debate in the community: is self-diagnosis valid? For many, the answer is a resounding yes. If the tools, the coping strategies, and the community support for autistic people make your life better, then that's a win, regardless of whether a doctor signed off on it.
However, if you need workplace accommodations or government disability support, that official test to see if you have autism becomes a legal necessity. You have to weigh the cost against the benefit.
Real Indicators You Might Want to Dig Deeper
While we wait for better diagnostic access, there are specific "internal" experiences that are highly indicative of autism.
- Sensory Processing: It’s not just "not liking loud noises." It’s feeling like a specific frequency of a flickering light is actually stabbing your brain.
- Bottom-Up Processing: Most people see a forest first, then the trees. Autistic brains often see every individual leaf, then the branch, then the tree, then finally the forest. It’s a detail-heavy way of existing.
- Monotropism: This is the tendency to have a "tunnel vision" focus. When you're into something, the rest of the world ceases to exist. It’s more than a hobby; it’s a nervous system state.
- Social Camouflaging: If you have to manually remind yourself to blink, nod, and make "listening noises" during a conversation, you are masking.
Moving Toward Action
If you’ve taken an informal test to see if you have autism and the results are pointing toward the spectrum, don't panic. It doesn't change who you are; it just changes the manual you use to operate yourself.
Start by reading. Look for "lived experience" accounts rather than just medical textbooks. Read Loud in a Quiet World or follow advocates like Chloe Hayden. See if their internal world matches yours.
Next Steps for Clarity:
- Gather Your "Evidence": Write down your sensory "icks," your social struggles, and your childhood obsessions. Don't filter it.
- Use Validated Screeners: If you haven't yet, take the CAT-Q (Camouflaging Autistic Traits Questionnaire). It’s specifically designed to see how much you’re hiding your true self to fit in.
- Find a Neuro-Affirming Provider: If you go for a professional assessment, ask the provider upfront: "What is your experience with adult diagnosis and the female/non-binary phenotype?" If they say they only test kids, keep walking.
- Audit Your Environment: Before you even get a diagnosis, start acting like you have one. Buy the noise-canceling headphones. Give yourself permission to leave the party early. See if these "autistic" accommodations actually make your anxiety go down.
Identifying as autistic isn't about looking for a "disorder." It’s about finding the vocabulary for a brain that’s simply wired for a different frequency. Whether you end up with a clinical stamp or a personal realization, the goal is the same: a life that actually fits.
