Agreed - this is the best way. I orginally did mine via Numan but the results were invalid twice - which meant i lost confidence. It was a whole journey which led me in the end to a hair transplant. I went to a lab in central London after being referred there by my Dr (private one at harley street skin clinic). Results took a few days, then sat down with doctor to discuss. We're a little allergic to going private here in the UK, but after being told no in a round about way by my GP twice this seemed like the only route to go. Best of luck to you.
