The short answer is no. Never specifically checked (never actually tested, that I know of), nor recently changed. I will see if my oncologist will order the test to be included in my next labs, in six weeks.
With the multivitamin, it seems unlikely, but I think it is good for anyone that's older to get a baseline read at some point. AFAIK, most symptoms of B12 don't emerge until it's quite low. My friend thought her dad's dementia was hitting her early and it turned out to just be a B12 thing. Note: Most doctors just order the serum test (and that's what I've had), but MMA and homocysteine tests are supposedly more accurate.
I think perhaps I over-celebrated the better-than-usual results in that part of July's lab reports, and the contrast with yesterday's worse-than-usual numbers has spooked me. It is hard not to over-react.
It must be very frustrating. So many of these numbers can vary so much depending on what you've done/eaten over the past month. And then others don't seem to budge at all no matter what you do. (I'm looking at you Vit D!) But it seems like there are many things to celebrate in your recent report so you seem to be doing many things right.
So, who is doing the NYT's Pips?
I've basically abandoned Strands for Pips. I start on Hard but a few times when I just can't see it, I go back and do the easier levels first and then when I go back to Hard I'm like, "Why didn't I see this before?"
