打開 wiki 條目25-hydroxyvitamin DThe vitamin D blood test most often used to assess vitamin D status.打開 wiki 條目Alkaline phosphataseAn enzyme signal that can come from bone, liver, bile ducts, or other tissues.打開 wiki 條目BMDBone mineral density: a measurement result, not a standalone diagnosis.打開 wiki 條目Bone scanA nuclear medicine imaging test used in selected bone disease and metastasis contexts.打開 wiki 條目CRPAn inflammation marker that can support infection/inflammation context but cannot identify the cause alone.打開 wiki 條目CTXA bone resorption marker that is timing-sensitive and context-sensitive.打開 wiki 條目CultureA microbiology clue used to identify organisms in infection contexts.打開 wiki 條目DXA / DEXAA low-dose X-ray method used to estimate bone mineral density, usually at the hip and spine.打開 wiki 條目eGFR / kidney functionKidney function context that can change phosphate, calcium, PTH, vitamin D, and bone turnover meaning.打開 wiki 條目ESRA nonspecific inflammation marker sometimes used with CRP and other clues.打開 wiki 條目Fracture and fall historyPast low-trauma fractures and falls often matter more than any single scan number.打開 wiki 條目FRAXA fracture-risk model clinicians may use; BioConst references the concept but does not embed a calculator.打開 wiki 條目MRIAn imaging method that can show marrow, soft tissue, early osteonecrosis, infection, or occult fracture context.打開 wiki 條目P1NPA bone formation marker used as context, not as a standalone diagnosis.打開 wiki 條目PhosphateA blood electrolyte tied to bone mineral, kidney function, PTH, and vitamin D context.打開 wiki 條目PTHParathyroid hormone: a calcium-phosphate control signal that must be read with calcium and kidney context.打開 wiki 條目Serum calciumBlood calcium is tightly regulated and does not directly tell how much calcium is in bone.打開 wiki 條目T-scoreA comparison between measured BMD and a young-adult reference database, mainly used in older adult contexts.打開 wiki 條目Vertebral fracture assessmentA low-dose lateral spine image often performed on a DXA system to look for vertebral compression fractures.打開 wiki 條目X-rayA basic imaging method for bone shape, fractures, sclerosis, lytic change, and deformity context.打開 wiki 條目Z-scoreA comparison between measured BMD and an age-matched reference group.
