Definitions of parathyroid graft functionality.
| Fully functional | Asymptomatic nonrenal patients | – Off calcium and vitamin D supplementation | – Eucalcemic with normal PTH levels and/or | grafted-to-nongrafted arm, PTH ratio >1.5 [11] | Renal patients | – PTH levels of 51 to 300 pg/mL with normal or decreased calcium levels [18] |
| Partially functional | Symptomatic nonrenal patients | – On calcium supplementation, with or without vitamin D supplementation | – Hypocalcemic with normal PTH levels and/or grafted-to-nongrafted arm, PTH ratio >1.5 [11] | Renal patients | – PTH levels of 21 to 50 pg/mL with normal or decreased calcium levels [18] |
| Nonfunctional | Symptomatic nonrenal patients | – On calcium supplementation, with or without vitamin D supplementation | – Hypocalcemic with low PTH levels and/or grafted-to-nongrafted arm, PTH ratio <1.5 [11] | Renal Patients | – PTH levels <20 pg/mL with normal or decreased calcium levels [18] |
