With increasing incidence of metabolic diseases, these diseases have attracted wide attention in the medical field all over the world. It is estimated that about 20-25% of adults in the world suffer from metabolic diseases. Meanwhile, as a syndrome, metabolic diseases have no single cause. The use of animals in experimentation was and continues to be of great importance in medical research. Animal models of metabolic diseases provide an opportunity to examine correlations among different metabolic parameters. Creative Bioarray provides professional drug testing services using these models.
