什么是基因组医学？DNA与健康简明指南
20 January 2026
When most of us think about healthcare, we picture blood tests, scans, and routine check-ups. However, there’s another tool quietly changing the way medicine is practiced: genomic medicine.
Genomic medicine looks at your DNA, the unique genetic code that makes you who you are, to better understand your health. It helps doctors assess disease risks, explain unexplained symptoms, and even predict how your body might respond to certain treatments.
More than just identifying rare genetic diseases, genomic medicine is also about personalised, proactive care, tailored to each individual.
What Exactly Are DNA and Genomics?
Think of DNA as your body’s instruction manual. It plays a role in the following areas:
- How your body grows and functions
- Your risk of developing certain health conditions
- How you respond to medications
- Health conditions that can run in families
Genomics, on the other hand, looks at all your genes together, and how they interact with your lifestyle and environment. By understanding this bigger picture, doctors can make more precise and personal healthcare decisions.
How Is Genomic Medicine Different from Regular Medical Tests?
Traditional medical tests usually focus on what’s happening right now, such as symptoms, blood results, or organ function.
Genomic testing looks a little deeper. It can help to:
- Identify genetic causes behind unexplained symptoms
- Detect inherited health risks before symptoms appear
- Guide early screening, prevention, or treatment
- Provide useful information for family members who may share similar risks
For some patients, genomic testing provides answers when routine tests fall short.
Who Can Benefit from Genomic Medicine
Genomic medicine can benefit individuals or families at different stages of life, including:
- Individuals with a strong family history of cancer or inherited conditions
- Couples planning a pregnancy who want to understand carrier risks
- Parents of children with unexplained developmental or medical concerns
- Patients seeking clearer diagnoses or more targeted treatment options
- Anyone who wants to take a proactive approach to long-term health
Why Genetic Counselling Matters
Genetic testing is more than just a laboratory test. Understanding the results is equally as important, and this is where genetic counselling comes in.
A genetic counsellor helps patients to:
- Decide whether genetic testing is appropriate
- Understand what the results really mean (and what they don’t)
- Talk through medical, emotional, and family implications
- Plan next steps with confidence
Genetic counselling ensures patients are guided before, during, and after testing, and are not left to interpret complex results on their own.
What Can Genomic Medicine Tell You?
Depending on the type of test, genomic medicine may offer insights into:
- Hereditary cancer risks
- Rare genetic conditions
- Carrier status for inherited disorders
- How your body responds to certain medications (pharmacogenomics)
- Disease risks and personalised prevention strategies
While not every genetic finding predicts disease, many can help guide smarter health decisions.
Taking the First Step
Genomic medicine is not about predicting your future. It is about empowering you with the right information to make informed choices about your health.
With professional guidance and the right support, individuals and families can take a more confident and proactive approach to their health. If you’re considering whether genomic medicine may be helpful for you or your family, a consultation at our Genomic Medicine Centre is often the best place to begin.
