Table 4 Formulas enabling comparison of parathyroid hormone concentration results determined with second- and third-generation tests*.
| Study group | Formulas enabling comparison of PTH (1–84) and iPTH test results |
|---|---|
| Patients with CKD stages 3–5 and 5D (n=205) | PTH 1–84=0.5181×iPTH+22.1596 |
| Dialyzed patients (HD+HPD) (n=127) | PTH 1–84=0.5181×iPTH+18.0595 |
| Patients in pre-dialysis period (n=78) | PTH 1–84=0.6187×iPTH+13.1944** |
