Ask a Pharmacist: Pharmacogenomic Testing for Pain Management (February 26th, 2018)



  • Good question - again this may vary from company to company, so something important to ask when considering your testing options. Usually this should be outlined in the patient consent form.



  • Another question from social: "Are patient results used in any other way than to inform their individualized pain management?"



  • Well the testing itself only analyzes genes, not drugs. So if there is a lack of scientific evidence that links having a certain gene variant with response to certain drugs, then testing will not be able to provide any recommendations regardless of the test result. As well, if a drug is not metabolized in the body by enzymes/proteins which are coded for by the genes than testing will generally not be able to provide any recommendations for that drug.



  • Are you aware of any common pain medications for which pharmacogenomic testing CANNOT be done?



  • Some common medications used to treat pain with pharmacogenomic linkages include: codeine, tramadol, oxycodone, hydrocodone, celecoxib, amitriptyline, nortriptyline, duloxetine.



  • What are some of the common pain meds that this kind of testing can be used for?



  • There are no risks to taking the test.

    However there are limitations which you should be aware of and ask about before getting tested. Good questions to ask would be what genes and drugs are covered by a test as it will vary between the different companies/tests.



  • Typically an HSA may be a benefit offered as part of your employer's benefit package. Also a good point from that definition is that CRA typically only recognizes a test that is prescribed by a physician, hence why it's a good idea to check with your plan to see if they will cover a pharmacogenomic test and under which conditions.



  • Someone from Facebook asks: "are there any major risks associated with getting this test done?"



  • @bryce.wong Thank you!



  • Here is a google'd definition -

    A Health Spending Account is a group benefit that provides reimbursement for a wide range of health-related expenses, over and above regular benefit plans. HSA's are administered in accordance with Canada Revenue Agency guidelines.



  • That's a good point RPh1982 - if you do have an Health Spending Account the test may be eligible for coverage, but I would just double check with your plan to see if they will cover the cost of the test.



  • @RPh1982 Are you able to explain in more detail what a Health Spending Account is?



  • @RPh1982 Okay, thanks



  • Although the costs are not covered by MSP you may be able to claim them through a Health Spending Account if you have that kind of benefit as part of an Extended Health plan.



  • Unfortunately, right now the tests are not covered under MSP.



  • @Clearwater The costs are not covered by MSOP but you may be able to claim them through a Health Spending Account if you have that kind of benefit as part of an Extended Health plan.



  • @bryce.wong Are any of the costs covered by MSP?



  • The costs range from $149 to $499.



  • There are a number of pharmacogenomic testing options in Canada that are sold through different channels such as through pharmacies, online or through physicians. The companies that are selling pharmacogenomic tests that I am aware of include myDNA, Genexys and Pillcheck.
