Table 5
PTH values measured with 2nd and 3rd generation assay according to sex. Reference ranges: 3rd generation PTH assay: 4.6–26.8 pg/ml; 2nd generation PTH assay: 10–57 pg/ml.
| | | All patients 108 (100%) | PTH 3rd generation (median and range) pg/ml | value | All patients 75 (100%) | PTH 2nd generation (median and range) pg/ml | value |
