@eirrol I had my testing done through Color Genomics about 5 years ago. First I had some genetic testing through my oncologist. Then my son needed to do testing at 35 because of my identified mutations so my oncologist suggested Color Genomics for him. You need a doctor's order for the gene mutations or a lab report showing a close relative has a mutation. When he did his testing, I saw they also offered the pharmacology testing so we both did that. Not sure if insurance will cover PGx. My son's cancer mutation and PGx testing was $250 and I could add on for $50. Not sure if Rx is needed for PGx or price for PGx only. You might query pharmacology testing or PGx on this Mayo site for other discussions and places that offer it. I couldn't post the link, but you can also google Mayo PGx for more info. I hope this helps.

I found this in another posting: In brief: "PGx is the study of how your genes may affect your body’s response to, and interaction with, some prescription or over-the-counter medications. Genes, which are inherited from your parents, carry information that determine characteristics such as eye color and blood type. Genes can also influence how you process and respond to medications. Depending on your genetic make-up, some medications may work faster or slower, or produce more or fewer side effects."
