Pharmacogenetic testing, also called pharmacogenomic testing, can help a doctor determine what type of drug, if any, should be prescribed for a health condition. Some people should not be taking certain types of prescription drugs because of genetic variations in drug metabolism. DNA affects the safety and effectiveness of a drug.
In some countries, such as the Netherlands, pharmacogenetic testing is becoming an important part of the healthcare system. Many people in Holland carry a card with test results that they share with their doctor before a drug is prescribed.
Here are some of the groups that provide pharmacogenetic testing:
- Dynacare – Canada
- EasyDNA – Worldwide
- Mayo Clinic – United States
- Safest Drug – United States
