Diagnosis & Tests

Font Size

How can you know if you have osteoporosis -- before your bones break? There are several ways to measure bone density. Learn about these osteoporosis tests.

Diagnosis

What Is Bone Mineral Density?

Almost 80% of bone density is determined by heredity, and 20% by lifestyle. Bone mineral density tests (BMD) shows how dense bones are and whether you have osteoporosis. This information helps determine which prevention or treatment steps are needed. Learn more.

Peak Bone Mass

Around age 30, your bones reach their maximum strength and density, known as peak bone mass.

Tests

DEXA Scan (Dual X-ray Absorptiometry)

The most common osteoporosis test is dual X-ray absorptiometry -- also called DXA or DEXA. It measures people’s spine, hip, or total body bone density to help gauge fracture risk. Read more.

Beyond DEXA: Other Bone Mineral Density Tests

Various methods can check bone density, including ultrasound and quantitative computed tomography (QCT). Bone density scores and cost may vary by testing method. Learn about these tests.

Who Should Get Bone Density Testing?

Bone density normally drops with age. When should you get a bone density test? Read guidelines from the National Osteoporosis Foundation.

Blood Test Markers

Whether you're being screened or treated for osteoporosis, your doctor may order a blood or urine test to see the metabolism of bone. This provides clues to the progression of your disease.

Bone Densitometry

Bone densitometry is a test like an X-ray that quickly and accurately measures the density of bone.
