    Signs and tests

    A physical exam reveals tenderness or pain in the bones, rather than in the joints or muscles.

    The following tests may help diagnose rickets:

    • Arterial blood gases
    • Blood tests (serum calcium)
    • Bone biopsy (rarely done)
    • Bone x-rays
    • Serum alkaline phosphatase
    • Serum phosphorus

    Other tests and procedures include the following:

    • ALP (alkaline phosphatase) isoenzyme
    • Calcium (ionized)
    • PTH
    • Urine calcium
