Bone Markers
- Vitamine D
- PTH (Parathyroid hormone)
- Calcium
- Phosphorus
When is it ordered?
Testing may be performed along with other tests such as a calcium, vitamin D, thyroid testing, and parathyroid hormone when bone loss is detected during a bone mineral density test (diagnostic imaging) and/or when a person has a history of unexpected bone fracture.
In children, testing may be done when they have signs and symptoms suggesting a metabolic bone disorder, such as:
- Bone and/or joint pain
- Increased frequency of fractures
- Delayed growth and bone development
- Deformed bones
- Brittle teeth
For managing and treating bone diseases, one or more bone marker tests may be performed prior to anti-resorptive or bone formation therapy and then typically 3 to 6 months later to monitor the effectiveness of treatment.
