vitamin Dtest utilizationIntroduction Testing of 25-hydroxy (25-OH) vitamin D serum levels has increased drastically in recent years and much of it is considered inappropriate based on current guidelines. Methods In consultation with our physician groups (experts and frequent orderers), we modified...

Vitamin D might play a role in counteracting COVID-19, albeit strong evidence is still lacking in the literature. The present multicenter real-practice study aimed to evaluate the differences of 25(OH)D3serum levels in adults tested for SARS-CoV-2 (acute COVID-19 patients, subjects healed ...

Results: An association was found between MMSE test scores and serum 25-hydroxyvitamin D3 levels, with a β-coefficient of 0.05 (p = 0.01). Vitamin-D-sufficient patients had significantly higher MMSE scores as compared to vitamin-D-insufficient ones. No association was found with the ...
The mean serum 25(OH)D level among school girls (17.86 ng/mL) was lower than that of boys (19.12 ng/mL). The prevalence of vitamin D sufficiency during 2014 was only 17.2%, but increased to ~45% in 2016. Conclusions: The prevalence of VDD and insufficiency among children in the ...
diagnosed NAFLD in Chinese men who present with normal BMI and liver enzymes as detected by routine clinical test- ing. Specifically, the men with NAFLD in this study cohort had remarkably decreased serum 25(OH)D3 levels compared to their non-NAFLD counterparts. In addition, the serum 25(OH...
Figure 1shows the hospitalization durationaccording to serum vitamin D level. Pearson correlation indicated a significant relationship between vitamin D level and hospital stay (P = 0.007; r = 0.553). Using ANOVA, the relation between groups was also significant (P = 0.006); this was followed by...
Here at OmegaQuant, we’ve identified a sufficiency vitamin D serum level as a minimum of 30 ng/mL and above that minimum, is an optimal level that can reach—but should not exceed—100 ng/mL. Why is Testing Important to Rule Out a Vitamin D Deficiency?
