Correlation between peripheral neuropathy and low RBC?

@ray666 - I have my neuro doc appointment in September and I'm going to ask her to recheck my B-6. I went back on my labs and I don't see it for past 3 - 4 years. They check the B-12 each year but not the B-6 which I know low B-12 is a smoking gun but elevated B-6 can cause issues as well. My PCP did not order it. From a neurologist standpoint, I will also ask if there are any other lab tests that should be ordered along with B-6.

Hi, Ed (@njed)

Reviewing copies of my old lab reports shows me that my B-12 has been checked routinely but not my B-6. I see that the NIH's RDA for B-6 is 1.7 mg/day. The NIH's UL (upper level) for B-6 for adults is 100 mg/day, and that includes what's absorbed as pyridoxine (supplement)." My daily B-6 absorption of B-6 from pyridoxine alone is 70 mg (two 35 mg EB-N5 capsules), so I'm under the UL of 100 mg/day, at least from the pyridoxine –– but what about my dietary daily intake? and my baseline B-6 level? That's critical info I don't have –– and that's why I'm chasing my neuro to get a script for a good, all-inclusive B-6 test.
