Overview The Bone-Specific Alkaline Phosphatase (BSAP) test measures the level of an enzyme produced by bone-forming cells (osteoblasts). It is a sensitive marker of bone formation and helps assess bone metabolism and skeletal health.
Why is this test done?
Evaluate bone formation activity
Monitor osteoporosis treatment effectiveness
Assess metabolic bone disorders
Detect conditions associated with increased bone turnover
Monitor bone healing after fractures
Conditions Associated with Abnormal BSAP Levels
Osteoporosis
Paget's disease of bone
Osteomalacia and rickets
Hyperparathyroidism
Bone metastases
Healing fractures
Chronic kidney disease-related bone disorders
Sample Required
Serum
Preparation
No special fasting is usually required unless advised by your healthcare provider.
Benefits of the Test
Specific assessment of bone formation
Helps differentiate bone-related ALP elevation from liver causes
