谱析（上海）生物科技有限公司提供——Vitamin B2 in Whole Blood 质谱诊断方案
 
一、说明
The term "vitamin B2" covers three vitamers: riboflavin, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). FMN and FAD are the effective forms of vitamin B2 and are synthesised in vivo from riboflavin by phosphorylation. Vitamin B2 is important for energy production and enzyme functions as well as for the fatty acid and amino acid synthesis. The undersupply with vitamin B2 is mostly attributed to a general malnutrition. It is often seen in persons with risk factors such as alcohol problems, advanced age and extreme dietary habits.The RECIPE test kit offers a short analysis time (easy sample preparation, short run time) and can be easily combined with test kits for the vitamins B1 and B6 (see combi kit).
