Calcium
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
Calcium is a vital mineral measured in the Basic Kidney Profile to evaluate mineral metabolism, which is often disrupted in renal disease. The kidneys play a major role in calcium homeostasis by activating Vitamin D and regulating calcium reabsorption. Monitoring calcium is essential for diagnosing CKD-MBD (Chronic Kidney Disease—Mineral and Bone Disorder), hyperparathyroidism, and potential bone density loss associated with kidney failure.

Why Context Matters
Roughly half of serum calcium is bound to albumin. If a patient's albumin levels are low (common in kidney or liver disease), the 'total calcium' result may look low even if the active (ionized) calcium is normal. A 'corrected calcium' calculation or an Ionized Calcium test is often necessary for accuracy.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
