What department to register for blood glucose and lipid check depends on the level of hospital where the patient is seen. If the patient is in a community hospital or a hospital in a rural area, he or she can register for general medicine or internal medicine. If the patient is in a tertiary care hospital or above, he or she can register for endocrinology or endocrine metabolism. Because the monitoring of blood glucose and blood lipids are related to metabolism, if abnormalities occur, you need to go to the endocrinology department for diagnosis and treatment. If there is a combination of heart disease, such as coronary heart disease, you need to go to the cardiovascular medicine department for treatment first. In general, when performing lipid tests, you need to ensure a low-fat diet 1 week in advance, and you should fast on the day of the test. For fasting blood glucose test, fasting and water fasting for more than 8 hours are required to make the blood glucose and lipid test results more accurate. The normal range of fasting blood glucose for normal adults is about 3.9-6.1mmol/L. If the glucose tolerance test is done, the blood glucose should be less than 7.8mmol/L 2 hours after the test. If the fasting blood glucose is ≥7.0mmol/L or the glucose tolerance test is ≥11.1mmol/L 2 hours after the test, and the results of the two tests exceed the standard value, diabetes should be alerted. The diagnostic criteria for dyslipidemia are total cholesterol ≥6.2mmol/L, triglycerides ≥2.3mmol/L, LDL cholesterol ≥4.1mmol/L, HDL cholesterol <1.0mmolL, meeting any one of these criteria can be diagnosed as dyslipidemia, suggesting possible hyperlipidemia.
