Table 4.
Blood donors divided according to the cutoffs of 25OHD3 levels, deficiency (≥50 nmol/L), and sufficiency (≥75 nmol/L) and according to PTH levels obtained with the third-generation assay (>26.8 pg/ml versus >4.6 and ≤26.8 pg/ml and <4.6 pg/ml).
| All patients 108 (100%) | PTH 3rd generation >26.8 pg/m 28/114 (25.0%) | PTH 3rd generation >4.6 and ≤26.8 pg/ml 86/114 (75.0%) | PTH 3rd generation <4.6 pg/ml 0/114 (0%) | p value | |
|---|---|---|---|---|---|
| 25OHD3 < 50 nmol/L | 61 (100) | 16 (26%) | 45 (74%) | 0 (0%) | 0.74 |
| 25OHD3 ≥ 50 nmol/L | 47 (100) | 11 (23%) | 36 (77%) | 0 (0%) | |
| 25OHD3 ≥ 75 nmol/L | 7 (100) | 2 (29%) | 5 (71%) | 0 (0%) | 0.82 |
| 25OHD3 < 75 nmol/L | 101 (100) | 25 (25%) | 76 (75%) | 0 (0%) |
