Description
Why It’s Done:
• To diagnose and monitor conditions that cause abnormal calcium levels, such as hypercalcemia (high calcium) or hypocalcemia (low calcium).
• To evaluate parathyroid gland function, kidney disease, vitamin D disorders, or bone diseases like osteoporosis.
• To investigate symptoms such as muscle weakness, confusion, fatigue, or bone pain that may be linked to calcium imbalances.
• To monitor calcium levels during treatment for certain medical conditions or after surgery affecting calcium metabolism.
Preparation:
• Usually, no special preparation is required.
• Some doctors may recommend fasting for a few hours before the test for best results.
• Inform your healthcare provider about any medications, supplements, or medical conditions, as these may affect calcium levels.
• Blood is drawn from a vein, typically at a clinic or hospital.
