I came to the same result -high B6, alt was within range but on the low side, checked the genes and found heterozygous variant. Edited to say: I do not have hypo….? My genes don’t process enzymes as actively as they could. I also have the MTHFr variant and COMt. There is a lot of stress on the pathways. One has to take the active form of B6 P5P because the body may not actually be getting enough B6 if there is a bottleneck, pyroxidine is the inactive form. I still have undiagnosed problems though. Hashimotos (known) apparent swelling of lymph nodes, random unexplained pain. At one point I was diagnosed with fibromyalgia. I’ve had 15+ years trying to get to the bottom of it and labs come back normal so doctors just throw their hands up. I had to pay out of pocket to do additional testing to find TPO levels (thyroid antibodies) and nutrition. I have no science background so it’s been kind of interesting to learn all of this new information.
