Hmmm… I’ll take a stab.
I think lab results are interesting and can tell you how you’re doing – especially when you have trends in the results. (I’m an engineer, so I LOVE having data that I can put on a chart!)
But… Doctors are still ‘practicing’ medicine. Biology is complex. What’s “average” or “normal” for one person could be “out-of-range” for someone else (on either side of the spectrum).
So… I guess I do like lab results, and I think you should pay attention to them (and listen to your Doc, too) – but I would treat them secondary to what your body is telling you. I think the key is figuring out how to “hear” what your body is saying.
