The assessment of bone disease in patients undergoing dialysis primarily focuses on calcium, phosphorus, and parathyroid hormone (PTH) levels. These three lab values are interrelated and play a crucial role in bone metabolism.

Calcium is essential for bone health and maintaining proper bone density. In patients with kidney disease, calcium levels can become altered, leading to conditions such as osteoporosis or renal osteodystrophy.

Phosphorus is another critical component. Patients with chronic kidney disease often have difficulty excreting phosphorus, leading to elevated levels. High phosphorus can result in an imbalance that negatively impacts calcium levels and bone health.

PTH is a hormone that regulates calcium and phosphorus levels in the body. When calcium levels drop, the parathyroid glands release more PTH to increase calcium levels by pulling it from the bones, increasing intestinal absorption, and promoting renal excretion of phosphorus. Monitoring PTH helps assess the parathyroid function and the body's response to calcium and phosphorus levels.

In the context of dialysis, understanding the levels of calcium, phosphorus, and PTH is vital for diagnosing and managing bone disease, making these values critical for effective treatment and patient care.
