What Is PGx Testing? Personalized Medicine
How Pgx Testing is Beneficial
Pharmacogenomics is the study of how your genes influence the way your body responds to medication. Your genetic makeup influences how your body processes and breaks down certain drugs, which explains why some people experience strong benefits from a medication while others see little to no effect. Genetics also provides data on who may develop more side effects from certain medications.

PGx Testing Steps and FAQ Discussion
Pharmacogenomic (PGx) testing analyzes a patient's genetic makeup to predict how they will respond to certain medications. This information can help healthcare providers choose the most effective and safest medications and dosages for individual patients, potentially reducing adverse drug reactions and improving treatment outcomes.
1. Consultation and Ordering:
- Consultation with a Healthcare Provider: Discuss the potential benefits and limitations of PGx testing with a doctor to determine if it's appropriate for you.
- Test Ordering: If deemed necessary, your healthcare provider will order the PGx test, specifying the genes to be analyzed based on your medical history and current or potential medications.
2. Sample Collection:
- Sample Collection Process:
- Cheek Swab: A healthcare professional or you (with at-home kits) will gently rub the inside of your cheek with a special swab.
3. Laboratory Analysis:
- DNA Extraction and Purification: The DNA is extracted from the collected sample and purified in the laboratory.
- Genotyping: The purified DNA undergoes analysis to identify specific genetic variations (variants) in the genes of interest.
- Reporting: The laboratory generates a report that includes the identified genetic variants and their potential impact on drug metabolism and response.
4. Results Interpretation and Application:
- Review by Healthcare Provider: Your healthcare provider will review the PGx test results and discuss them with you.
- Integration with Clinical Information: The PGx results are interpreted in the context of your medical history, current medications, and other relevant factors.
- Medication Management: Based on the PGx results and other clinical information, your healthcare provider may adjust your medication regimen, including drug selection and dosage.
Important Considerations:
- Limitations: PGx testing is not a perfect predictor of drug response, as other factors like age, overall health, and organ function can also influence how your body responds to medications.
