Pharmacogenetic Testing

Finding the right medication can feel like trial-and-error—especially when side effects, poor response, or multiple medication changes get in the way. Pharmacogenetic Testing (PGx) helps you and your provider make more informed decisions by showing how your body may process certain medications based on your genetics.

At California Holistic Health Center, we use PGx testing as part of a whole-person approach—so your treatment plan is more personalized, safer, and easier to fine-tune over time.

What is Pharmacogenetic Testing?

Pharmacogenetic testing is a simple test (usually a cheek swab) that looks at specific genes that can influence:

• How your body metabolizes certain medications (too fast, too slow, or typical)

• Your likelihood of side effects

• Which medications may be more likely to be effective for you

This can help reduce unnecessary medication “guessing” and support a clearer path forward.

Who is PGx testing for?

PGx testing may be helpful if you:

• Have tried medications that didn’t work well

• Experienced side effects or sensitivity to medications

• Have switched medications multiple times

• Want a more personalized approach before starting a new medication

• Have a family history of medication sensitivity

• Are taking multiple medications and want clearer guidance

Medications PGx commonly supports

PGx testing is often used to guide decisions around medications such as:

• Depression and anxiety medications

• ADHD medications

• Mood stabilizers

• Sleep support medications

• Pain medications (in some cases)

• Other commonly used prescriptions (depending on the panel)

(Testing panels vary, and we review what’s most appropriate for your needs.)

What you’ll receive

After testing, you’ll get:

• A clear report of how you may respond to certain medications

• A provider review to explain results in plain language

• Personalized recommendations to support medication selection and dosing discussions

• A plan that considers your overall health—stress, sleep, lifestyle, and goals

What to expect

1. Schedule your appointment

2. Quick sample collection (often a cheek swab)

3. Lab processing and report generation

4. Results review visit with your provider

5. Personalized next steps (medication options, adjustments, or discussion points)

Frequently asked questions

Does PGx testing tell me the “perfect medication”?
It doesn’t guarantee a perfect match—but it can strongly reduce trial-and-error by showing which options may be better tolerated or processed more effectively.

Is this the same as genetic testing for disease risk?
No. PGx focuses on medication response, not disease diagnosis or ancestry.

Can I do this if I’m already on medications?
Yes—PGx can still be helpful if you’re experiencing side effects, limited benefit, or planning adjustments.

Will this replace medical judgment?
No. PGx results are one tool used alongside your medical history, symptoms, and overall clinical evaluation.
