DNA Testing in Malaysia

Genetic testing is quite common among Malaysians to learn more on their wellness, their ancestry traits or drug sensitivity [1]. Generally, genetic tests may require invasive or noninvasive methods. It can be performed on a sample of blood, hair, skin, amniotic fluid, or other tissue. Noninvasive procedure known as buccal swab uses a small brush or cotton swab to collect a sample of cells from the inside surface of the cheek [2]. 

How to test DNA? 

DNA sample collection can be done by professional healthcare or self-test. Professional DNA test usually is an invasive method, requiring blood samples, tissue samples, or semen samples [3]. Alternatively, general genetic testing can also be done non-invasively, it can be obtained from cheek tissue, a process called buccal swab test. Conveniently, DNA testing can be done at home as the procedure is very simple and user-friendly. 

The buccal swab test procedure involves easy steps. Typically, the self-test kit includes a unique device identifier (UDI) for swabbing the cheek. For example, place the UDI sponge towards the back of the mouth and rub along the lower gums in a back-and-forth motion. Repeat this action ten times, avoiding the teeth. Then, gently repeat the rubbing motion on the opposite side of the mouth along the lower gums for an additional ten times [4].

Who is the test suitable for?

Genetic screening tests may be suitable for people who have families with genetic illness. It helps them to screen whether the traits are passed down and they become a carrier or likelihood for themselve to acquire the medical condition. Common genetic illnesses to be screened include Down syndrome, familial hypercholesterolemia, autism, cancer and many more [5].  

Pre-marital couples are also widely known to engage in genetic testing to check the risk of having thalassemia, sickle cell anemia or Tay-Sachs disease [6]. Pregnant mothers and babies older than 6 months old are eligible to do the test. Normally, they will take noninvasive tests such as buccal swab or cell-free fetal DNA testing. 

Why do I need a DNA test?

DNA testing holds significant value as it can conduct over 500 genetic tests and provide results for more than 300 traits using just one sample. Genetic screening, facilitated by such tests, allows for tailored prescriptions based on an individual’s genetic makeup, thereby enhancing treatment efficacy and minimizing side effects. Furthermore, it empowers individuals to choose personalized blood tests that prioritize factors related to heart health, particularly beneficial for those with a family history of heart disease.

This proactive approach to genetic screening contributes to improved health outcomes by identifying actionable health traits. It enables individuals to make targeted adjustments to their diet or exercise routines, effectively mitigating the risk of conditions like heart disease. Moreover, genetic screening represents a long-lasting investment, providing individuals with the knowledge to make informed healthcare decisions throughout their lifetime. This not only improves overall health outcomes but also reduces the occurrence of medical issues in the long run.

In conclusion, genetic testing can offer valuable insights into an individual’s predisposition to certain conditions or their carrier status. However, it’s crucial to recognize that the results are not always definitive and may sometimes be inconclusive or misleading, potentially causing unnecessary concern [7]. Therefore, while genetic testing can be beneficial for some individuals, it’s essential to approach it with caution and seek guidance from healthcare professionals to fully understand and contextualize the results based on individual circumstances.
