A test that measures bone mineral density (BMD) to diagnose conditions like osteopenia and osteoporosis.

Front

CT Scan (Computed Tomography)

Back

A detailed imaging test that combines multiple X-ray images to provide a cross-sectional view of bones, joints, and surrounding structures.

Front

Arthroscopy

Back

A minimally invasive diagnostic and surgical procedure that uses a camera to view and treat joint conditions.

Front

Blood Tests - Calcium Levels

Used to assess bone metabolism and detect abnormalities like hypercalcemia.

Front

Blood Tests - Vitamin D Levels

Back

Evaluates bone health by measuring vitamin D, essential for calcium absorption.

Front

Blood Tests - Alkaline Phosphatase (ALP)

Back

Elevated levels may indicate bone disorders or rapid bone turnover.

Front

Biopsy

Back

A procedure where a small sample of bone tissue is removed for examination, often used to diagnose bone cancer or infections.
