Finding the Right Medication Through Pharmacogenomics

Patient Story #2

Last updated 3 July 2026

“Genetic testing ensures you receive the most effective medication without unnecessary delays — especially when it is needed the most.” 

After a heart attack, Mr Tan (not his real name) was prescribed medication but soon experienced troubling breathlessness. At first, it was not clear whether the symptoms were due to the heart condition or the treatment itself. 

That was when pharmacogenomics (PGx) testing provided the answer.

The transition was not just about switching medication — it was about clarity and confidence. While the genetic report itself was technical, pharmacists took the time to explain what the results meant in everyday terms. 

For the patient, it was eye-opening: 

“Genetic testing equips doctors with more precise information to make better treatment decisions.” 

Today, this experience has changed the way the patient views healthcare. Instead of trial-and-error, genetic testing now ensures the right drug, first time. 

And his message to others? 

“Concerns about genetic privacy are personal. But if you are not overly worried, testing is worth it. The benefits far outweigh the risks — for you and your loved ones.” 

Details on how your genes can help you choose the right medicine.
