Can my vit.D blood test 25 hydroxy be wrong? My vitD is usually on the high side: 75 to 100. Recently I had a micronutrient test done by Spectracell lab. the only deficiency was VitD. , I told them their test was flawed because vitD happens to be my strongest since my breast cancer in 2010. They maintain their test is superiort to regular blood test and I'm probably not absorbing the vit. I suggested the blood not being fresh enough (2days to get there) but they said they checked it and it was fine. I had this test done 2 years ago and was impressed because they uncover an insulin and glutathione deficiencies but this time, I don't believe them. What do you think?
