| White, n = 88 | 105.4 ± 32.7 (47.8–230.3) |
| Infant | |
| Black/African American, n = 28 | 24.1 ± 23.1, (≤2.5–113.8)b |
| Hispanic, n = 32 | 29.4 ± 20.8, (≤2.5–89.5)b |

a
Profound deficiency by the IOM’s Guidelines is defined as a 25(OH)D concentration <25 nmol/L (10 ng/mL) for both adults and children (including neonates and young infants).1
b
The level of detection of the assay for 25(OH)D is 2.5 nmol/L.
