This "fasting test" number is lower because only the triglycerides made by the liver and carried in the VLDL cholesterol will be measured – not the triglycerides you get from food. If your doctor has asked you to fast for a test (usually for 10-14 hours) then your triglyceride level should be below 1.7mmol/L. HEART UK experts state that we should aim for a non-fasting triglyceride level below 2.3mmol/L. National guidelines in the UK no longer recommend a fasting blood test (where you fast for a period of time before your blood test). The triglyceride test measures the triglycerides carried in chylomicrons and VLDL cholesterol. Triglyceride levels should be measured when you have a cholesterol test as they can also contribute to your risk of developing heart disease, and other disease of the heart and blood vessels. Triglycerides are measured with a simple blood test. This form is carried in a different type of lipoprotein known as VLDL cholesterol.
The body also makes its own supply of triglycerides in the liver. These carry the triglycerides in the blood stream to our tissues to be used for energy straight away, or stored for later. When we eat foods containing triglycerides, such as meat, dairy products, cooking oils and fats, they are absorbed by our intestines and packaged into parcels of fats and protein called chylomicrons (a type of lipoprotein).
Triglycerides are our main source of energy and, as they are so important, we have two supplies: one from our diet and one made by the liver.
