What calcium phosphorus level is abnormal?

In the context of calcium and phosphorus levels, the combined product is critical for assessing mineral metabolism, especially in patients undergoing hemodialysis. The normal range for the calcium-phosphorus product is typically around 30 to 55 mg/dL.

When the calcium-phosphorus product exceeds 55 mg/dL, it indicates an increased risk for vascular calcification and other complications related to mineral and bone disorders. Therefore, a calcium-phosphorus product greater than 55 mg/dL is considered abnormal and warrants clinical attention.

The choice of a value that is less than 55 is within the normal limits, indicating that the mineral balance is acceptable. Likewise, values like 50 also fall within the normal range. Thus, identifying a level higher than 55 mg/dL directly correlates with abnormal results, reflecting an imbalance that can significantly impact patient care.
