🦴 Calcium-Phosphate Product
Calculate the calcium-phosphate product, relevant to vascular calcification risk.
Calcium-Phosphate Product
Calcium (mg/dL)
Phosphate (mg/dL)
When to use
CKD-mineral bone disorder assessment.
How it works
Ca × PO₄ product (mg/dL units). > 55 mg²/dL² is associated with calcification risk.
Key points
- Mainly used in CKD-MBD.
- KDIGO now emphasises individual Ca and PO₄ trends.
- High product warrants review of phosphate control.
