Final answer:
In Paget's disease, calcium and phosphorus levels are typically normal, but alkaline phosphatase and urine hydroxyproline are elevated, indicating increased bone turnover and collagen breakdown.
Step-by-step explanation:
When describing calcium, phosphorus, alkaline phosphatase (alk phos) and urine hydroxyproline levels in Paget's disease the typical findings are as follows:
- Calcium: Levels are usually within normal limits although they can occasionally be elevated due to increased bone turnover.
- Phosphorus: Often within normal ranges, but could potentially be affected by the disease process or treatments.
- Alk phos: Typically elevated, reflecting increased bone turnover.
- Urine hydroxyproline: Elevated, indicating increased collagen breakdown and bone turnover.
Therefore, the most accurate description would be: Calcium: Normal; Phosphorus: Normal; Alk phos: Elevated; Urine hydroxyproline: Elevated. Paget's disease involves abnormal bone destruction and formation, leading to the classic lab findings of elevated alkaline phosphatase and urine hydroxyproline levels while calcium and phosphorus levels can vary but are often normal.
