Bone Chemistry – 4 parameters (ALP Alkaline Phosphatase, Phosphate Serum, Magnesium Serum, Calcium – Corrected Serum) is a blood test panel that evaluates key minerals and enzymes involved in bone health and metabolism. It measures alkaline phosphatase (ALP) for bone formation activity, phosphate for bone mineralization, magnesium for bone structure support, and corrected calcium to assess available calcium levels adjusted for albumin. This panel helps detect issues like bone disorders or imbalances in mineral homeostasis.
Indications of the Test
Order this test for symptoms like bone pain, unexplained fractures, muscle weakness, fatigue, or conditions such as osteoporosis, rickets, or kidney disease. It’s also useful for monitoring vitamin D deficiency, parathyroid issues, or Paget’s disease where mineral levels fluctuate. Abnormal results may signal poor bone turnover or mineralization problems.
Patient Preparation/Instructions
No special fasting is required, but stay hydrated and avoid calcium or magnesium supplements for 24 hours before the test. Inform the lab of any recent fractures, liver issues, or medications like antacids that affect minerals. Labtestzote serves Nairobi and Kenya with convenient walk-in options.
