Long-standing chronic renal failure causes secondary hyperparathyroidism. When the glands become autonomous and both calcium and PTH are high, it is tertiary hyperparathyroidism.
- Hypercalcemia from alfacalcidol (B) would suppress PTH, not raise it.
- A high calcium level is not a normal dialysis finding.
- 'Primary hyperthyroidism' is a thyroid diagnosis.
