Osteoporosis is one of the most common skeletal disorders affecting the health of the population. In the early stages of the disease, there are usually no obvious clinical manifestations, and osteoporosis is often detected only after a fracture occurs. The specific tests include: 1. Laboratory tests: This test includes blood calcium, blood phosphorus, blood alkaline phosphatase and blood parathyroid hormone levels. In addition, bone renewal markers, morning urine calcium/creatinine ratio, etc.; 2, auxiliary examinations: first, bone imaging, X-ray can detect fractures and other lesions, such as vertebral compression fractures, etc.; second, bone density test, which is currently the gold standard for diagnosing osteoporosis.
