In patients with CKD, the development of metabolic bone disease involves a complex interaction of phosphate, calcium, and PTH. As such, serial assessments of all three parameters are recommended in patients with CKD stage G3a-G5D to guide treatment. According to the KDIGO guidelines, reasonable monitoring intervals are as follows:

  • CKD G3a-G3b – Serum phosphate and calcium, every 6-12 months; PTH, based on baseline level and CKD progression

  • CKD G4 – Serum phosphate and calcium, every 3-6 months; PTH, every 6-12 months

  • CKD G5, including G5D – Serum phosphate and calcium, every 1-3 months; PTH, every 3-6 months
