Do rats need to fast when measuring thrombopoietin in rats?

Platelet has a specific morphological structure and biochemical composition, and has a relatively constant number in normal blood. It plays an important role in physiological and pathological processes such as hemostasis, wound healing, inflammation, thrombosis and organ transplantation rejection. Platelets are found only in mammalian blood. There is no fasting requirement when we test the serum plasma of normal rats for thrombatin. According to the situation in the literature, the thrombopoietin in serum plasma of rats was generally detected 24h after administration, and the requirement of fasting in rats was not mentioned. It is suggested that you can make reference selection according to the experimental purpose and literature.
