How is rickets diagnosed?
A blood test may be done to measure the amounts of the minerals calcium and phosphorus. X-rays of the affected bones are obtained and a musculoskeletal examination reveals tenderness or pain of the bone itself, rather than in the joints or muscles. In some occasions, a bone biopsy, in which a small sample of bone tissue is removed for analysis, also may be needed to confirm the diagnosis.
Other tests that are helpful in diagnosing rickets are:
- Urine calcium
- Calcium (ionized)
- ALP (alkaline phosphatase) isoenzyme
