DNA testing, or genetic testing, comes in many types – e.g. relationships, ancestry, cancers, medical diagnosis, etc. In general, genetic testing is a type of test that can identify changes in the genes, chromosomes or proteins in your body. Genetic testing takes a sample of either blood, skin, hair, tissue or amniotic fluid. Depending on the type of test, some tests may be able to confirm or rule out if you have a genetic condition. It may also help determine your chances of developing or passing on a genetic disorder (e.g. thalassemia).
On the other hand, Pharmacogenomics examines the relationship between an individual’s genetic makeup and their body’s response to medications. It investigates how genetic variations can influence the efficacy, safety, and metabolism of medications. With Pharmacogenomics, it can help healthcare professionals to personalise treatment plans, and optimise medication selection and dosage for patients. While it is not necessary to have both tests done together, what type of DNA tests you intend to do will give you different outcomes. When DNA tests are performed accurately, the test results may help to diagnose or uncover potential or the tendency to develop certain health condition(s) / disease(s). But when our PRECISE Pharmacogenomics (PGx) test is performed, it can help doctors choose the safest, most accurate and most effective drug, including dosage according to you, while minimising/preventing Adverse Drug Reactions (ADRs).
Preventive measures or treatment can be lifesaving, be it now or in the future.
