Vitamin D blood test misses a lot
Blood Test Misses a lot (VDW 3439)

  • Vitamin D from coming from tissues (vs blood) was speculated to be 50% in 2014, and by 2017 was speculated to be 90%
  • Note: Good blood test results (> 40 ng) does not mean that a good amount of Vitamin D actually gets to cells
  • A Vitamin D test in cells rather than blood was feasible (2017 personal communication)
  •    Commercially available 2019
    • However, test results would vary in each tissue due to multiple genes
  • Good clues that Vitamin D is being restricted from getting to the cells
    1) A vitamin D-related health problem runs in the family
    2) Slightly increasing Vitamin D shows benefits (even if conventional Vitamin D test shows an increase)
    3) Vitamin D Receptor test (<$30) scores are difficult to understand in 2016
    • easier to understand the VDR 23andMe test results analyzed by FoundMyFitness in 2018

    4) Back Pain

Genes on the web

  • The Genes That Never Go Out of Style Sept 2018
    about 16% of all genes were known by 1991; that same 16% are the focus of half of all Genetics papers in 2015
    25% of all genes have never been the focus of a single scientific paper
