At a Glance

Why Get Tested?

To help evaluate and monitor the rate of bone resorption and formation; to monitor some metabolic bone diseases such as osteoporosis; to detect Paget disease

When to Get Tested?

When a bone mineral density scan indicates reduced bone density; before and periodically during treatment for bone loss to evaluate effectiveness, to determine if the rate of loss has decreased or the rate of bone formation has increased

Sample Required?

A blood sample drawn from a vein in your arm or sometimes a urine sample

Test Preparation Needed?

Fasting may be required before testing; samples are typically collected in the morning.
