Test results. Can you advise please.
After great advice on this forum regarding my thyroid nodules, I requested from my GP surgery the same tests as are provided in the Blue Horizon Golden Thyroid Test. The clinician seemed to want to help and I thought almost everything would be tested. However, these are my results and, as is clear

Is it worth doing pernicious anemia test with active B12 of 68?
I'm working on getting my levels of B12, folate, ferritin and D up to ideal levels, if I can, for my thyroid. I recently got a B12 result from monitor my health of 68 pmol/L (range 38-210). I have read that you can still have B12 deficiency even if your B12 is around my level (I heard over 70 is needed

Silent Reflux and B12 Deficiency- Any Link?
Hello! I was diagnosed with low B12 following a blood test in December last year, on injections but only had 3 of the 6 loading doses then was moved on to one every three months due to severe side effects that worried my GP. Had my first of the 3 monthly ones a few weeks ago and all went well. I saw

B12 supplementation query
My active B12 level in 2022 was 66.1 pmol/L and following advice on our wonderful forum I began taking Thorne basic B complex. This raised my levels to 78.6 pmol/L in 2023. This year my B12 level is 76.3 pmol/L. So it hasn't continued to increase to the recommended 100 pmol/L. For the past ten days

vitamin results
I’ve just received my vitamin results. My ferritin is 52, serum vitamin b12 level 462 ng/l, serum folate level 16.5 ng/l (range 3-20), vitamin D 90. A year ago my ferritin was 48, vitamin b12 331 and folate 12.3. I’m disappointed my ferritin has only gone up by 4. I tried cutting tea out near meal

Once I start supplementing B12, will my B12 blood tests still be accurate?
I would like to know if blood tests will still be a useful measure of my B12 levels, once I have started supplementing B12. I would be testing active B12. The reason I ask is that I have read pernicious anemia people saying that once they start injections (and supplements too maybe), that the B12 blood

Wondering if iron dose age should vary depending on weight please?
Hi I usually take Ferrous fumerate to help with iron levels. I’m wondering if this should vary depending on weight please as when I was ordering Three Arrows which is on its way, it asks for weight to work out a daily dose. Mine came to needing between 20 and 40ish a day. I’ve been & until it arrives

B12 deficiency treated before folate deficiency
Please could someone post a link supporting the importance of this fact for PhonixGrace . Explaining B12 and folate are tested together normally for a good reason. If folate is supplemented before B12 . The b12 deficiency can be masked/ missed. Nerve/neurological damage can occur . Once B12 injections

New (to me) symptom of severe iron deficiency
I'd never heard of this before and thought it might be useful to somebody... People who are severely iron deficient can have the whites of their eyes (the "sclera") develop a blue tinge. https://www.semanticscholar.org/paper/Blue-sclera-secondary-to-severe-iron-deficiency-Hassen-Chirurgi/0ae45491752fa575014a5dce5588c7acdcd2f4a7

My doctors won’t investigate

Advice on Vitamin D, K2 and Folate
Hi Everyone I have recently had a range of blood tests done, unfortunately I don’t seem to have any results for thyroid which they were supposed to do. My GP has asked me to make an appointment to speak to her, so I’ll ask why I haven’t got any results for thyroid and whether the test was done.

Is serum folate levels the level of b12?
I received this as a blood result 3 weeks after receiving my b12 injection but I am confused. Does this tell me the level of b12 in my blood or folate? There are no other test results that refer to b12. I am currently suffering very badly with the symptoms of low b12 despite having my 3 monthly injections
