From what I've read on this site, DHT (dihydrotestosterone) testing is more important than T (testosterone) testing. So I asked my Kaiser Permanente med onc for it. He asked what clinical trials establish that there is a survival benefit to DHT testing. I also have read people on this site saying DHT testing is standard operating procedure, or even that it's malpractice not to do it.
If you are provided with DHT testing in a hospital or medical center, & best of all if it's a national comprehensive cancer center, would you please write about it here? Then maybe I (or you) can find out why they provide it, or I can see if my med onc would be willing to ask. He needs more evidence than just that Snuffy Myers does it for his patients.
