It is possible to perform endocrine hormone testing with a meal, and testing after a meal will not affect the accuracy of the results. This is the case for gonadotropin series, thyroid hormone series, cortisol hormone, etc. Because eating will not affect the results of hormone measurement, it is OK to draw blood in fasting state, and there is no problem to draw blood in post-meal state. If endocrine hormones are checked along with liver and kidney function, electrolytes, blood glucose, lipids and other indicators, these indicators require blood to be drawn in an absolutely fasting state, and in order to avoid patients having their blood drawn twice, all tests should be drawn in a fasting state as much as possible.
