Study Notes
Triacylglycerols (Triglycerides)
- Main source of triglycerides in the blood is from the diet
- Considered as an independent coronary heart disease risk factor
- Hypertriglyceridemia causes fatty liver disease and pancreatitis
Forms of Lipoproteins
- Triglycerides travel in the blood within two main forms of lipoproteins:
- VLDL (Very-Low-Density Lipoprotein)
- Chylomicron
Triglyceride Levels in Blood
- Value in the blood shows variation with:
- Age
- Sex
- Diet (elevated after a meal, especially a high-fat meal)
- Specific timing of elevation:
- Chylomicron: about 2 hours after a meal
- VLDL: about 4 hours after a meal
Laboratory Testing
- To obtain accurate results, test should be performed in a fasting state
- Single result interpretation is not dependable due to within-individual variation
Interpretation of Results
- Desirable: [no specific value mentioned]
