Hi @brighterdays, I had United Healthcare in 2013 and they covered the CYP2D6 test at that time, but again I have genetic mutations and that can make a difference. It might be worth calling your insurance provider to ask so you don't get stuck with a big bill. Let them know it would be to see if you can metabolize Tamoxifen because the test may only be covered for certain drugs. Yes, I do think your oncologist could offer better customer service and check for you. I hadn't heard of anything race related so I googled and get conflicting data on that. I didn't see any real alarm bells for any race, but google that yourself to see what you find. I did read only 5% of the general population is a CYP2D6 poor metabolizer, but again google and see what you find. You also don't want to be an ultrarapid metabolizer. You want to be a normal metabolizer. Don't we all just want to be normal? Normal is underrated. 🙂 Best of luck to you.
