What is genetic screening?
Genetic screening uses genomics technologies to detect known genetic variations, or genetic markers, in your DNA. These markers are associated with diseases or disorders such as cardiovascular diseases, metabolic disorders, and cancers.

Beyond diseases, genetic screening is also able to identify traits that may affect health, wellness, and fitness. These include traits that are associated with metabolism of nutrients, anti-aging, cellular detoxification, antioxidative capacity, and diet and weight management.

Through genetic screening, your doctor can also better understand how your body may react towards certain types of medications. Variations in DNA may play a part in how well a certain type of medication works in your body. The information from your report may help your doctor to prescribe the type and dosage of medication that best suits your genetic profile. In addition, genetic markers may also indicate your risks for adverse reactions towards certain types of medications.

Why is genetic screening important?
Genetic screening can detect possible risks for many genetic diseases before symptoms appear. Based on the detailed results, you can work closely with your doctor to develop a suitable health management plan to mitigate or delay the possible onset of disease through preventive actions.

Do I need genetic screening?
Genetic screening could help if you:

  • have a family history of genetic illnesses and would like to know how these illnesses influence your risk factors
  • are interested to identify wellness and fitness traits that can affect your quality of life
  • want to know about any possible adverse reactions that you may have towards a drug
  • want to be more proactive in managing your health, and the health of your loved ones
  • are planning to have children, but are concerned about any genetic illnesses that may be passed down to them

What is the difference between a normal blood test and genetic screening?
A normal blood test detects changes in your body when a disease is already present. Genetic screening detects risks for a disease even before the onset of that particular disease. It is best to take both types of tests together to get a complete picture of your health risks.

Is genetic screening safe?
Genetic screening is absolutely safe. Samples are collected using a buccal swab, which involves rubbing a swab against the inner side of the cheek. A blood sample can also be used for the screening.

Do I have to repeat the test?
Each type of genetic screening test only has to be taken once in your lifetime.

How soon can I get my results?
Depending on the type of tests requested, genetic screening and analysis in the laboratory generally take between 14 working days, from sample collection to receipt of results.

How accurate is genetic screening?
All tests are accurate for known genetic markers. Complex diseases may require comprehensive tests that utilise a wider range of markers, or DNA sequencing. Your doctor can advise on the necessity for such tests. It is still important to validate the results from genetic screening with medical tests.
