Serum triglycerides are one of the components of blood esters. Triglycerides are in a dynamic balance in the body. The level of blood esters can change with dietary changes and can vary widely. In addition, their levels increase with age, and tend to be higher especially in middle-aged and elderly people who are overweight. What are the screening methods for elevated serum TG level? 1.Blood biochemical six tests The blood biochemical six tests are the preliminary examination of human blood condition, including alanine aminotransferase, creatinine, urea nitrogen, serum glucose, triglyceride and total cholesterol. 2.Big biochemical examination Big biochemical examination mainly includes liver function, kidney function, electrolytes, blood sugar, blood lipids, cardiac enzyme spectrum and other examination contents. 3.Lipid test Lipid test is a quantitative measurement method for lipids in blood (plasma). Lipids are the general term for neutral fats (triglycerides and cholesterol) and lipids (phospholipids, glycolipids, sterols, steroids) in plasma, which are widely present in the human body. They are essential substances for the basic metabolism of living cells. 4.Serum triglyceride The current methods of TG determination are enzymatic method and chemical method, and the enzymatic method has one-step endpoint method and two-step endpoint method, the main advantage of two-step endpoint method is to remove the interference of free glycerol. Measurement of triglycerides is useful for understanding lipid metabolism, liver function (liver is one of the organs for synthesizing triglycerides) and the diagnosis of diseases caused by atherosclerosis.
