Description
Why It’s Done:
• To diagnose the cause of abnormal calcium levels (high or low)
• To help detect parathyroid disorders, such as hyperparathyroidism or hypoparathyroidism
• To monitor patients with chronic kidney disease who are at risk for bone and mineral disorders
• To evaluate symptoms like muscle cramps, fatigue, bone pain, or kidney stones
• To guide treatment decisions for conditions affecting calcium balance
Preparation:
• Fasting (usually overnight) may be required—confirm with your healthcare provider.
• Inform your doctor about all medications, supplements (especially calcium and vitamin D), and any recent procedures.
• Avoid vigorous physical activity before the test, as it may influence calcium and PTH levels.
• Follow any additional instructions provided by your healthcare team to ensure accurate results.
