Clinical Testing & Screening Guide

Tests for Children (0–18 Years): A Parent’s Guide

A parent-friendly clinical guide to understanding which diagnostic and screening tests a child may need from birth through 18 years, what each test evaluates, and how to prepare. This is general information. Your child’s doctor decides which tests are needed.

Newborn Tests (0–28 Days)

0–28 days
What tests does a newborn need?

Newborn tests evaluate essential health from birth. These include the Apgar score, baseline growth measurements (weight, length, head circumference), hearing and critical congenital heart disease screens, red reflex eye exam, hip exam, and bilirubin checks for jaundice. Blood glucose or blood group/Coombs tests are done for at-risk babies, alongside the newborn metabolic screen.

Note: Exact schedules vary by guideline and by your child's health. Follow your doctor's advice and the national immunisation and screening schedule.
