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