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

Hypertension is one of the leading causes of human death and disability. CYP24A1 regulates vitamin D activity and is closely linked to hypertension. However, the relationship between CYP24A1polymorphisms and hypertension risk remains unclear.

This case-control study included 503 hypertensive patients and 498 healthy controls from the Chinese Han population. The genotypes of CYP24A1 polymorphisms were detected using the Agena MassARRAY method. The association between genetic variations of CYP24A1and hypertension risk was evaluated with odds ratios (OR) and 95% confidence intervals (CI) in genetic models.

We found that rs56229249 of CYP24A1significantly decreased the hypertension risk in homozygote (OR 0.51, 95% CI 0.29-0.91, p = 0.022) and recessive models (OR 0.51, 95% CI 0.29-0.91, p = 0.023). Further stratification analyses indicated that hypertension risk is related to age and sex, rs2762934 polymorphism increases hypertension risk among younger subjects (<61 years), and rs1977297 influences the risk of hypertension among older subjects (≥61 years). In addition, rs2762940 is related to hypertension risk in men, and rs56229249 is a protective factor against hypertension in women.

Our study suggests that genetic variations of the CYP24A1gene were significantly associated with susceptibility to hypertension in the Chinese population.
