# Recommended Screening & Diagnostic Pathway for Down Syndrome Under 7

Down syndrome is confirmed by karyotype after antenatal or birth detection; in the under-7 child the pathway centres on scheduled comorbidity screening (cardiac, audiology, thyroid, ophthalmology) and continuous structured developmental surveillance to start early intervention promptly.

*A child with Down syndrome rarely needs a label confirmed before support begins — but a clear, staged pathway turns suspicion into timely, coordinated care.*

## In short
Down syndrome (ICD-11 **LD40.0**) is most often suspected antenatally (combined first-trimester screening, NIPT) or at birth on recognisable phenotype, and confirmed by **karyotype/chromosomal microarray**. In the under-7 child the clinician's task is no longer diagnostic confirmation but structured developmental surveillance and proactive comorbidity screening, so that early-intervention therapy starts without delay.

## The pathway, briefly
**Confirm and characterise.** Where the diagnosis is clinical, send karyotype to define trisomy 21, translocation or mosaicism (translocation prompts parental karyotyping for recurrence counselling).

**Screen the known comorbidities — on schedule.** Following AAP/IAP health-supervision guidance: echocardiography in the neonatal period (≈50% have congenital heart disease); newborn and serial **audiology**; ophthalmology review; thyroid function at birth then periodically; haematology for transient myeloproliferative disorder; feeding, growth on Down-specific charts; cervical-spine symptom vigilance; coeliac and obstructive sleep apnoea surveillance as the child grows.

**Surveil development continuously.** Use a structured developmental measure at every health-supervision visit rather than a one-off screen — expressive language, fine and gross motor, and social-adaptive domains warrant the closest tracking, and a clinician-administered profile gives a reliable baseline to plan against.

## The Pinnacle way
A clinical **AbilityScore®** and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an app or this page. We translate the medical diagnosis into a measurable developmental baseline and a coordinated plan spanning [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) and [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate), tracked over time via the [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated). See the [Down syndrome pathway](/down-syndrome) for the full developmental picture.

## Trusted sources
WHO ICD-11 (LD40.0); AAP health-supervision guidance for children with Down syndrome via HealthyChildren.org; CDC developmental milestones; Indian Academy of Pediatrics.

**Next step —** Refer the child for a structured AbilityScore® baseline and an early-intervention plan at a Pinnacle Blooms Network centre.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
