35 years ago, I had a GP sit down with me and thoroughly explain my blood test results, making notes on the paper! I still have that paper. He said “ALWAYS get a copy of every blood test.” I have, since then. Often, I have found that I was one number from being considered “low” and needing meds, perhaps. At the same time, the doctor told me that everything was “Fine!” By finding this info out for myself I have prevented a lot of health problems with better diet and supplements and water! You can find all you need to know and to do, online. Hope this helps a lot of people, as it did me.
