    For those of you who are not a member of ConsumerLab.com, I thought I'd relay the following information. I must paraphrase and not copy and paste due to copyright issues.

    ConsumerLab just updated their report on Vitamin D tests. They say that the most common current methods of testing Vitamin D, immunoassay tests using Abbott Architect or Siemens Centaur-2 immunoassay devices, have an increased likelihood of reporting Vitamin D levels as deficient when they are not. ConsumerLab recommends using the older established method (LC/MS), [if you know what that is, I don't!], if you are concerned that your lab results are not accurate.

    I was taking 5000 iu of vitamin D, but my vitamin D 25 hydroxy was only 30.2 ng/ml. When my vitamin D was tested in the past it was higher so I'm hoping that it's a problem with my test rather than actual deficiency.
