Calcium/Phosphorous Ratio
The calcium/phosphorous ratio compares the levels of these two minerals, which work together in bone health and many cellular processes. The body keeps both within tight ranges through hormonal signals.
Why it matters: An imbalance between calcium and phosphorus can reflect changes in parathyroid signalling, kidney handling of these minerals, or vitamin D status. The ratio is one input among several in interpreting bone-mineral findings.

What is Calcium/Phosphorous Ratio?
The calcium/phosphorous ratio compares the levels of these two minerals, which work together in bone health and many cellular processes. The body keeps both within tight ranges through hormonal signals.
What might a high or low Calcium/Phosphorous Ratio mean?
An imbalance between calcium and phosphorus can reflect changes in parathyroid signalling, kidney handling of these minerals, or vitamin D status. The ratio is one input among several in interpreting bone-mineral findings.
What can affect Calcium/Phosphorous Ratio?
It may be higher with: Hyperparathyroidism, Vitamin D toxicity. It may be lower with: Hypoparathyroidism, Renal failure.
