Vitamins are a kind of trace organic substances necessary for human and animals to maintain normal physiological functions, and play an important role in the growth, metabolism and development processes of human bodies. Vitamins are not involved in forming human cells in vivo, nor provide energy to the human body; the human body has little demand for vitamins, but the deficiency of vitamins in the body causes metabolic disorder and various diseases, and the diseases are collectively called as vitamin deficiency. On the contrary, excessive intake of vitamins is likely to cause overload accumulation and even poisoning. The content of vitamins in the body is an effective index of the nutritional status, and the intake of the vitamins is especially important for pregnant women and infants. Vitamin monitoring is taken as a means for evaluating reasonable medication, improves the safety and effectiveness of vitamin use, realizes individuation of vitamin treatment, and is gradually paid attention by clinic.

The symptoms caused by vitamin deficiency or excess can be diagnosed by inspection, and the condition of vitamin deficiency or excess can be known by the content of vitamin in blood. Vitamin detection methods include electrochemical analysis, atomic absorption, mass spectrometry, and the like.
