The “normal” 25-hydroxyvitamin D lab range is between 20-56 ng/ml. As you can see in the chart below, this conventional range is really a sign of deficiency, and is too broad to be ideal. In fact, your vitamin D level shouldneverbe below 32 ng/ml, and any levels below 20 ng/...
Reference ranges are the test result values that are considered optimal for health. Results that fall outside the reference range may indicate a health issue. Reference ranges can vary by laboratory. Additionally, some labs may break down your levels of vitamin D2 and D3, while other ...
000 units over the previous 2 weeks, was asymptomatic, normocalcemic, and had normal renal function. Their vitamin D levels were well over the toxic lower limit (150 ng/mL) and were 535 ng/mL and 484.9 ng/mL, respectively. The 12-year-old was normocalcemic and had normal renal ...
Bolded P-values are considered statistically significant (P < 0.05). CPC = circulating progenitor cell; hsCRP = high-sensitivity C-reactive protein; sHR = sub-distribution hazard ratio; VDD = vitamin D deficiency. Discrimination analysis demonstrated that vitamin D status improved prediction of ...

We show that vitamin D levels were within lower range for patients and controls (48.8 ± 22.1 nmol/l and 53.4 ± 20.0 nmol/l, respectively). A significant positive association was found between vitamin D and ICV (p = 0.003, r = 0.22), folate was trend-significantly...
Vitamin D deficiency is a candidate risk factor for osteoporosis, characterized by decreased bone mineral density (BMD). We performed this two-sample Mendelian randomization (MR) analysis to investigate the causal effect of vitamin D on BMD. We extracted 143 single-nucleotide polymorphisms from a re...
Laboratory tests revealed hypercalcemia in all of these patients, with serum calcium level between 11.0 and 15.7 mg/dL, serum phosphates ranging from 2.0 to 8.6 mg/dL (normal range 3.5–5.0), and serum 25(OH)D between 164 and 1161 ng/mL. Differential diagnosis of hypercalcemia included ...
However, reference values of vitamin D are still not clearly defined. The Endocrine Society advised reaching serum 25(OH)D levels of at least 30 ng/mL (>75 nmol/L), preferentially to maintain levels in the range of 40–60 ng/mL (100–150 nmol/L) [2]. Accordingly, vitamin D ...
Your test report will indicate your blood level of vitamin B12, as well as the laboratory’s reference range. Reference ranges are the test result ranges that are considered normal. Keep in mind reference ranges can vary slightly depending on the laboratory used. A normal vitamin B12 level gene...
