Genetic Testing

Pharmacogenomics uses information about a person’s genetic makeup, or genome, to choose the drugs and drug doses that are likely to work best for each particular person. By studying a human’s enzymes we can predict how fast or how slow a person may metabolize a medication and also the likelihood of a person having side effects. More importantly, we can determine which medications are genetically optimal for each person, increasing response times to medication trials. With a simple swab of the inside of your mouth, clinicians can use your genetic map to guide medication treatment decisions.

MTHFR gene mutation testing is also available in conjunction with genetic testing. MTHFR is located on chromosome 1 and is involved with the conversion of folic acid and dietary folate to their active form, l-methylfolate. If a person has an intermediate activity or reduced activity of their MTHFR gene they may be more prone to symptoms of depression and anxiety.

All genetic testing and MTHFR screening will be completed with Samantha Winfrey, PMHNP-BC.

Thirty-minute Genetic Testing Appointments

Samantha Winfrey now offers 30-minute genetic testing appointments. In addition to the actual test, your appointment will include a thorough education on pharmaceutical genomics to include genetic mapping of antidepressants, antipsychotics, stimulants, and MTHFR conversion to help identify genetically optimal medications and speed up response times. All buccal swab collection, ordering, and processing of your genetic test will be completed on the same day.

Pricing for the test for individuals with commercial insurance is determined based on gross household income; find details on or call them at 888.496.2391 for more information about pricing. The appointment time itself is priced separately at $75 per 30-minute appointment.
