Patient's question:
My daughter had a trace element test when she was one year old. At that time, the doctor said she had a slight calcium and zinc deficiency, and her lead content was high. After that, she took calcium supplements and zinc gluconate oral solution. Now I want to have her re-examined and also learn about the specific contents of trace elements.What kind of help do I need: What are all the trace elements included in the test?
Doctor's answer:
Trace element (also known as minor element), traditionally, elements with a content greater than 1% in a research system (such as minerals and rocks) are referred to as major elements or principal elements, while those with a content between 1% and 0.1% are called minor elements. Elements with a content less than 0.1% are termed trace elements or minor elements. Some consider minor elements as trace elements as well, depending on the researcher's interest and the help it provides to the research question. Some believe that, in the Earth's crust and geophysics, all elements except for the most abundant ones like O, Si, Al, and Fe can be classified as trace elements. We also classify elements that exist in extremely small quantities in the human body, below 0.01% of body weight, as trace elements. Trace elements with certain physiological functions and must be obtained through food intake are called essential trace elements, including iron, copper, zinc, cobalt, manganese, chromium, selenium, iodine, nickel, fluorine, molybdenum, vanadium, tin, silicon, strontium, boron, rubidium, arsenic, etc.
