At birth (0 to 2 weeks)

Best for parents who want a complete genetic snapshot from the very start of life, a foundation for early prevention, development tracking, and personalised care.

Why it mattersWhy newborn screening matters.

Most genetic conditions in newborns show no symptoms at birth. The earlier you understand your baby’s biology, the more time you have to plan and act.

Screening in the first months turns invisible risks into decisions you can act on, when early intervention matters most.

  • detecting possible inherited conditions early

Families with genetic history

  • Learning whether your child may have inherited known variants
  • accessing preventive guidance before symptoms appear
  • making informed decisions about ongoing care

Preventive health planning

  • Actionable insights to guide nutrition, immunity, and growth
  • supporting early interventions and long-term wellness
  • a foundation of lifelong health understanding

Your report

What’s included in your Newborn Screening Report

A detailed analysis of your baby’s DNA across six body systems, metabolic, endocrine, immune, neurological, haematological, and more. Each section gives you and your paediatrician the earliest possible picture of your newborn’s health.

  • A clear overview of any genetic variants identified in your baby’s DNA that may be linked to early-onset or congenital conditions, each with its clinical relevance and inheritance type.

  • Detailed insight into the genes and specific variants analysed using whole genome sequencing, following international guidelines such as ACGS and ClinGen for precise classification.

  • Each variant is linked to its associated condition, with a brief explanation of the condition, its impact, and how it may influence your child’s health.

  • An easy-to-follow explanation of how inheritance works, helping parents understand whether a condition may be inherited from one or both parents, or arose spontaneously.

  • How identifying conditions early can support better long-term outcomes, including preventive measures and early interventions where applicable.

  • Even when no variants are detected, a minimal residual risk remains, explaining why no genetic test can completely rule out rare or undiscovered variants.

  • Definitions of the terms used and how the data is analysed, including reference databases such as ClinVar, gnomAD, and ClinGen.

Frequently asked questions

Why should I test my newborn if they seem healthy?

Many genetic conditions do not show symptoms immediately after birth. Early insight allows for monitoring, early support, and lifestyle adjustments that can improve long-term outcomes.

When is the best time to take the test?

The test can be done shortly after birth, ideally within the first few weeks of life, so any actionable findings can be addressed as early as possible.

How is the sample collected?

A gentle saliva sample is used. The process is completely non-invasive and safe for newborns. Detailed instructions are included in the kit.

What conditions are covered?

The report analyses over one thousand genes associated with inherited, metabolic, neurological, and developmental conditions that may affect infants and young children.

How accurate are the results?

Results are generated using whole genome sequencing technology with high depth and precision. Every finding is reviewed and validated by certified genetic experts before the report is finalised.

What happens if a variant is found?

If a clinically relevant variant is detected, a genetic counselling session is recommended. A specialist will explain what the result means, outline next steps, and provide guidance for any follow-up care.

Where can I see the results?

Results are uploaded automatically to your secure profile in the app, created with the email you provided at checkout. You’ll also receive an email with a direct link, and can download the report as a PDF anytime.
