Blood vitamin D

Vitamin D (VD) is a fat-soluble vitamin, which can be further divided into vitamin D2 and vitamin D3. Vitamin D2 is mostly found in plant-based foods and is synthesized from ergosterol in plants through sun exposure. Vitamin D3 can be synthesized in human skin and adipose tissue from 7-dehydrocholesterol through sun exposure. Vitamin D regulates calcium and phosphorus metabolism in the human body and plays a very important role in bone development and growth. Blood vitamin D, which measures the level of vitamin D in the blood, is an important indicator for evaluating whether the human body is deficient in vitamin D.

Bone density

Bone mineral density (BMD) refers to the amount of bone mineral per unit volume (volumetric density) or per unit area (areal density) of bone. It is an important indicator of bone strength, capable of predicting fracture risk or monitoring treatment response for related diseases. BMD is typically measured using X-rays. BMD measurement is currently the most common method used to diagnose osteoporosis, predict fracture risk, and evaluate the effectiveness of drug treatments.
