The following are the most common treatments of elevated alkaline phosphatase. [23] Treatment of the underlying condition. Once doctors identify the cause of elevated ALP and diagnose a treatment, the levels of alkaline phosphatase fluctuates back to normal; Removal of medication. Drugs can be associated with increased levels of alkaline ...
Alkaline phosphatase levels are usually high in hyperparathyroidism due to high bone turn over. In primary hyperparathyroidism, levels may remain within the normal range, but this is inappropriately normal given the increased levels of plasma calcium. [citation needed]
Also, the level of alkaline phosphatase increases if there is active bone formation occurring, as the enzyme is a byproduct of osteoblast activity (such as the case in Paget's disease of bone). [59] The level of alkaline phosphatase is much more elevated in metastatic prostate cancer cells than non-metastatic prostate cancer cells. [60]
An elevated level of alkaline phosphatase in the blood in combination with normal calcium, phosphate, and aminotransferase levels in an elderly patient are suggestive of Paget's disease. Markers of bone turnover in urine eg. Pyridinoline; Elevated levels of serum and urinary hydroxyproline are also found.

Alkaline phosphatase allows for mineralization of calcium and phosphorus by bones and teeth. [21] ALPL gene mutation leads to insufficient TNAP enzyme and allows for an accumulation of chemicals such as inorganic pyrophosphate [21] to indirectly cause elevated calcium levels in the body and lack of bone calcification.
The diagnosis of hyperphosphatemia is made through measuring the concentration of phosphate in the blood. A phosphate concentration greater than 1.46 mmol/L (4.5 mg/dL) is indicative of hyperphosphatemia, though further tests may be needed to identify the underlying cause of the elevated phosphate levels.

Serum leukocyte alkaline phosphatase is normal or elevated in leukemoid reaction, but is depressed in chronic myelogenous leukemia. The bone marrow in a leukemoid reaction, if examined, may be hypercellular but is otherwise typically unremarkable. [citation needed]
