Hello. This is my second post on this forum. Due to sudden, severe hair loss I'm seeing a Naturopath here in the U.S. She's an MD, but much more willing to treat and delve deeply into health issues that the mainstream docs I've seen. Here are some of my test results, which show I have Hashimoto's thyroid disease, low ferritin, and low-ish B12. I also have normal Magnesium and Zinc levels:
TSH: 3.27 uIU/mL (0.24 - 4.82) --my TSH has been around this number since at least 2015
Free T4: 0.72 ng/dL (0.59 - 1.61)
Free T3: 2.50 pg/mL (2.3 - 4.2)
Thyroid Perox AutoAb: 891 IU/mL (standard range: <35)
Vit D,25-Hydroxy Tot: 40 ng/ML (20-80) --I've been taking 2000iU VitD for a while now due to testing at 10 in 2016
Ferritin: 14 ng/mL (12 - 252)
RBC: 3.82 M/uL (3.90 - 5.40)
Hemoglobin: 12.1 g/dL (12.0 - 15.5)
Hematocrit: 35.7% (35.0 - 47.0)
MCV: 94 fL (80 - 100)
MCH: 31.7 pg (27.0 - 33.0)
MCHC: 33.9 g/dL (31.0 - 36.0)
RDW: Can't remember the number right now, but well within normal range.
Lymphocyte %: 22% (26.0 - 46.0)
Vitamin B12: 257 pg/mL (211 - 911) --tested at 284 in 2016
The doctor now has me taking all sorts of supplements, including iron, vitD, and magnesium and is starting me on a very low dose l-thyroxine to lower my TSH level. I'm taking another couple supplements to try to address the Hashimoto's.
She was also very concerned about my B12 level and is thinking it's a B12-specific absorption problem since my magnesium and zinc levels are within normal parameters.Today she recommended I start B12 injections, which I did.
My question has to do with this: When I asked her if I should be tested for PA, she said she didn't really think it was necessary because it wouldn't change the course of treatment. She thinks I'll need a few B12 injections to get my level above 500 and can then continue to do periodic injections or do a trial of sublingual B12 to see if that's sufficient. Her expectation is that I'll need lifetime B12 supplementation. So, how important, if at all, is it that I get tested for PA? Any advantages to doing so if I have it?
