Just what I need, another controversy over lab test ranges...
I just had some more bloodwork done and the results of my vitamin B12 is listed as in range: 377 (211-911). But reading on other forums and in that online encyclopedia that must not be named it appears that the B12 ranges in this country may be outdated and incorrect. I understand that the Japanese have a more progressive view on B12 deficiency and have raised their lower range to 550. This would mean that I'm actually very deficient.
I do have many B12 deficiency symptoms, including weird migraines that obscure my vision for periods of time, twitching thumbs and eyelids, etc. I do plan to go on the sublingual suppliments and retest later. I'm wondering if others here have had this same experience or have been told they are "normal" with their labs and may want to re-explore this issue.
I was also surprised to see that my D levels are below range: 22.6 (32-100), and I live in Arizona and am about as brown as a caucasian person can be
. Obviously I'm not converting well due to my hypothyroid issues.
