Table 1 Definition of vitamin D saturation status based on serum calcidiol levels
From: Vitamin D for prevention of sternotomy healing complications: REINFORCE-D trial
Serum calcidiol concentration in ng/mL and nmol/L, respectively | Vitamin D saturation status—interpretation of values | |
|---|---|---|
< 10 ng/mL | < 24 nmol/L | Deficiency |
10–20 ng/mL | 25–49 nmol/L | Insufficiency |
20–30 ng/mL | 50–74 nmol/L | Sufficiency |
30–50 ng/mL | 75–125 nmol/L | Optimal level (considered for this clinical trial) |
> 100 ng/mL | 250 nmol/L | Risk of toxicity |
