I'm scheduled for a RBC folate and a ferritin test tomorrow.
1. Which is the better folate test, serum or RBC?
I've only been tested twice for folate, Nov 2014 and Feb 2015. It was a serum folate test and both times was high, >24.0 (range 3.0 - 17.0). So my doctor thought my folate was fine. Could it have been fine in serum but low in the cells? I convinced my doctor to test the cells as I am doing rather poorly lately. Have never been told to supplement folate (nor anything else for that matter) so I haven't. When I get a B12 injection I feel terrible for a couple of days, could it be folate I need?
2. I'm also getting a ferritin test. My HMO doctor has only tested it once, in Nov 1014, it was 113 (range 22 - 391 ng/mL). Shouldn't ferritin be regularly monitored? My PA treatment regimen began in Nov 2014.
I have had ferritin tested by a naturopathic doctor on the side as I felt I was getting dreadful treatment by my HMO. Ferritin has decreased over time and in June it was 61 (range 10 - 232 ng/mL). Do I need to supplement?
I did finally convince my doctor to order a ferritin test as well, since it hasn't been tested in so long.
