Genetic counselling is guidance from a specially trained professional — a genetic counsellor or clinical geneticist — for people and families facing a possible genetic condition. The counsellor explains how a condition could affect you and your family, interprets genetic tests, helps you understand risk, supports informed and unpressured decisions, and offers emotional support. It is deliberately non-directive: a good counsellor supports the decision that is right for you rather than telling you what to do, and it matters both before and after any genetic test.

Genetic counselling is not emergency care. Its value is helping you make informed choices and understand what a result means for you and your blood relatives — including the option of not testing at all.
What it is
Genetic counselling is the process by which a clinical geneticist (a doctor) and genetic counsellors help an individual or family understand genetic conditions and the choices around them. They explain inheritance and risk, interpret test results, address concerns, support decision-making, and provide psychological support to help people adapt to a condition or a risk. It is education and support combined, not a single test or treatment.
Who is referred
People are commonly referred when there is a family history of a genetic condition or of an inherited cancer, when a child has a suspected genetic condition or developmental concern, when planning a pregnancy or already pregnant (including known carrier status), after an abnormal screening result, or before predictive testing for a condition that runs in the family. You do not need to have already decided to test — counselling helps you decide whether testing is even useful for you.
Taking a family history
A central part of a session is taking a detailed family and medical history, often drawn as a family tree (pedigree). Who in the family had which condition, at what age, and how everyone is related all help the counsellor work out how likely a condition is and how it might be inherited. This is why it helps to gather as much family health information as you can before the appointment — conditions, ages of onset and relationships — since the pedigree drives the whole risk assessment.
What happens in a session
The counsellor explains inheritance patterns and risk in plain terms, discusses whether a test would actually be useful and what it could and could not tell you, and covers the benefits, limits and risks. If you choose to test, they take informed consent, because testing is always voluntary. Throughout, the counselling is non-directive and supportive — the aim is to help you reach the decision that fits your values and circumstances, with your emotional wellbeing kept in view.
The emotional and family dimensions
Genetics professionals specifically help with the social and emotional aspects of testing. Because a result can reveal information about other family members, counselling helps you think through how and whether to share findings with relatives, and how to manage feelings such as anxiety, guilt or relief. For many people, this support is as valuable as the technical explanation, and it continues whatever result comes back.
Why it matters before and after a test
Before a test, counselling ensures you understand what it can and cannot reveal, its family and privacy implications, and gives you a genuine informed choice. After a test, it helps interpret the result in the context of your personal and family history, plan next steps — which may include cascade testing of relatives — and provides emotional support, which is especially important when a result is uncertain. Counselling can be worthwhile even if you ultimately decide not to test at all, because understanding your family history and risk can be valuable in itself. It also helps you prepare for the different results a test might give — including an uncertain one — so that whatever comes back, you already have a plan and support in place.
Privacy and personal choice
Part of counselling is thinking through practical considerations — who else is affected by a result, how your data and results are handled, and any insurance or employment considerations — before you decide. None of this is meant to push you toward or away from testing; it is there so that your choice is fully informed. The decision, and the pace of it, stays with you.
How to access it in Singapore
Genetic counselling is accessed by referral to a clinical genetics service. In Singapore these are provided through restructured hospitals and specialist centres, including services associated with KK Women’s and Children’s Hospital (KKH), the National University Hospital (NUH) and SingHealth, with cancer genetics through the National Cancer Centre Singapore. Bring your family health history, ask what happens to your data, and remember that counselling supports your decision either way. Writing down which relatives had which conditions, and at roughly what ages, before your appointment makes the session far more useful, and you can always take time to think rather than deciding anything on the spot. HealthHub and MOH offer general information.
