All I can report is I haven't had a tuff time convincing the PCP to order the vit D test as part of annual blood work. I had even gotten buy in for including testosterone, since that was a suspected issue with CH back in the day. Was as surprised as anyone to see the report come back showing a fully macho testosterone level at that time?!? I think for my upcoming annual bloodwork I'll also request the calcium and the other D3 regimen related thingy (the name of which escapes me at this moment) - I have requested those before, but in the end they didn't make it onto the panel.
