近年来,生物医学样品中的微量元素研究已引起各学科的极大兴趣。人体内的微量元素含量与人体的健康休戚相关,某些微量元素的过量或缺乏使机体患病为测定微量元素在人体内的含量,可选择测定人体各种样本如血、尿、头发、指甲、软组织等中的微量元素含量来一定程度上反映体内微量元素的水平。但上述样本都有自己的局限性。尿反映人体微量元素的损失,但不反映体内存贮。传统上,临床化学工作者选择血样,但它反映几小时到几天期间微量元素水平;血样可分成全血、血清、血浆、红细胞
In recent years, trace element research in biomedical samples has drawn great interest from various disciplines. Trace elements in the human body are closely related to the health of the human body. Excess or lack of certain trace elements makes the body ill. To determine the content of trace elements in the human body, various samples of human body such as blood, urine, hair, nails , Soft tissue and other trace elements content to a certain extent, reflect the level of trace elements in the body. However, the above samples have their own limitations. Urine reflects the loss of human trace elements, but does not reflect the body’s storage. Traditionally, clinical chemists choose blood samples, but it reflects levels of trace elements from hours to days; blood samples can be divided into whole blood, serum, plasma, red blood cells
