Normal reference value of serum triglycerides: 0.45-1.69 mmol/L.

Based on the 2007 Chinese Guidelines for the Prevention and Control of Dyslipidemia in Adults, the fasting (12-hour fasting) triglyceride level of 1.70 mmol/L or less is considered appropriate; 1.70-2.25 mmol/L is considered to be borderline elevated; ≥2.26 mmol/L is considered to be elevated; and ≥2.26 mmol/L is considered to be elevated. and ≥2.26 mmol/L were considered elevated.

Expanded information:

Lipids are complex in composition and include cholesterol, phospholipids, fatty acids, and small amounts of other lipids in addition to triglycerides. Under normal conditions, plasma triglycerides maintain a dynamic balance.

Precautions:

1. Serum triglyceride levels are affected by lifestyle, diet, age, etc., and fluctuate widely within and between individuals.

2. Eat as little lipid-containing food as possible for 2 to 3 days before blood collection, and draw blood on an empty stomach for 12 hours to rule out and minimize the effects of diet.

There are two main sources of triglycerides in plasma:

1, exogenous: fat ingested from food in the intestinal tract, absorbed by the intestinal mucosa under the action of bile acids, lipase, and synthesized into triglycerides within the epithelial cells of the intestinal mucosa.

2, endogenous: the body's own synthesis of triglycerides mainly in the liver, followed by adipose tissue. The main function of triglycerides is to supply and store energy, but also to fix and protect the internal organs. Serum triglyceride measurement is a routine item in lipid analysis.
