Why Early Detection Matters
The window where change is fastest is also the shortest.
A child's brain forms most of its neural architecture before the age of five. Identifying root causes early — even biological ones like Cerebral Folate Deficiency — can shape years of progress. But meaningful change is possible at any age.
The neuroplasticity window
Until age 5, the brain forms new neurons and connections at a rate it never will again. After that, new connections still form — but the foundation is laid.
2–5y — Optimal window for biological identification & intervention.
Symptoms aren't always the cause.
Biology often is.
Many children with autism have an underlying biological factor — folate-receptor antibodies, gut imbalance, oxidative stress, nutritional deficiency — that worsens behaviour and learning. These are testable. And many are treatable.
Yodaara starts where it matters: a focused screening that can change everything.
Identify, don't guess.
FRAT can confirm or rule out one of the most well-studied biological contributors to autism risk — in just one test.
Treat what's actionable.
Cerebral Folate Deficiency responds to specific folate supplementation under medical supervision — not generic vitamins.
Build a real care plan.
Whether your child is 2 or 12, results give you a starting point — and Yodaara guides you through every next step.
Early identification can unlock the right support.
Best outcomes before 5 years
Early childhood is a critical window when the brain adapts rapidly. Starting personalized support during this time can lead to faster progress and help reduce challenges with communication, behavior, and learning as your child grows.
If your child is above 5:
Never too late to start. The brain keeps adapting through neuroplasticity. Early years help, but children 5+ can still make strong progress with consistent support — improving communication, behavior, learning, and independence.
What is FRAT
A spotlight test that often hides in plain sight.
FRAT (Folate Receptor Antibody Test) IgG variant is a simple blood test that detects autoantibodies that block folate from reaching the brain. When folate can't cross into the brain, neurological development is impacted. This condition is called Cerebral Folate Deficiency (CFD).
It's been linked to autism, developmental delays, and neurological symptoms — but the most important fact: it's identifiable and often treatable.
FRAT is one important marker, not a full diagnosis.
For the complete biological picture, our Autism Decoder Panel evaluates 19 markers across 7 categories — see below.
The Data
0%of children on the autism spectrum are FRAT positive — making it one of the most consistent biomarkers identified in the field.
of FRAT-positive children show measurable improvement in language, social communication & behaviour after treatment.
Signs parents notice
Trust what you're seeing. It deserves an answer.
These are the most common early signs parents bring to us. None of them, on their own, mean autism — but together, they often mean it's time to investigate. The FRAT test is a small, decisive first step.
Difficulty understanding social cues
Doesn’t respond to name, struggles to read facial expressions or take turns in play.
Avoiding eye contact
Looks away during interactions or seems unable to hold a steady gaze when spoken to.
Repeating actions or behaviours
Repetitive movements, lining up toys, insistence on routines, or echoing phrases.
Delayed or unusual speech
Limited vocabulary for age, scripted speech, monotone delivery, or loss of words once gained.
Sensitivity to touch or sound
Strong reactions to specific textures, food temperatures, loud sounds, or clothing tags.

A comprehensive diagnostic panel designed to help identify biological, metabolic, genetic, immunological, and nutritional factors that may contribute to autism-related symptoms and developmental challenges, enabling more personalized and targeted care.
Questions parents ask
Still figuring it out?
That's normal.
Most parents come in with the same questions. If yours isn't here, our team is one call away.
Between 2 and 3 years old, you can start seeing symptoms. It’s better to always intervene before children reach 5 years — after that, no new neurons are formed, only new connections and lengthening of axons. That said, the brain continues to adapt at every age, so meaningful progress is possible at any stage.

Stories from parents
When the right answer
changes everything.
These are the parents who stopped chasing specialists and started building a plan. Their children's progress is what we measure success by.
“We had been to four different specialists before someone even mentioned FRAT. Within seven weeks of testing through Yodaara, we had real answers — and a plan that actually moved the needle.”

Mother to a 4-year-old · Hyderabad
“Our son tested FRAT positive at age three. Six months into treatment, his speech started catching up. The home collection alone was a relief — he hates clinics.”
Vikram & Sneha
Parents · Bengaluru
“I went directly for the full Autism Decoder Panel. The doctor walked us through every finding for ninety minutes. We finally had something to do — not just something to worry about.”
