What are the normal triglyceride levels in the blood?

Adults: 50-150 mg/dl
Children up to 9 years old: 40-75 mg/dl
Children from 10 to 17 years old: 45-90 mg/dl

In the International System of Units (SI), triglycerides in the blood are measured in mmol/L. The normal triglyceride levels in the blood in the SI are:

Adults: 0.56-1.7 mmol/l
Children up to 9 years old: 0.45-0.85 mmol/l
Children from 10 to 17 years old: 0.50-1.02 mmol/l

Why normal levels can differ across different labs?

Each laboratory must establish its own normal ranges for triglycerides in the blood. These ranges depend on the makeup of the local population, the technologies used and the accuracy of the measurement. There may be also slight differences in the normal levels, according to age, gender, race or ethnic origin, geographic region, diet, type of sample and other relevant status.

Your doctor will study the results along with your medical record, screenings, physical condition, symptoms and any other relevant information about your situation.

What is the role of triglycerides in the blood?

Triglycerides are a type of lipids (fats) present in the blood. They are used as an energy storage.

When we eat more calories than we need, the body stores part of those calories in the form of triglycerides. These triglycerides circulate through the bloodstream to provide energy to the muscles. After a meal, new triglycerides are added to the bloodstream and the levels of triglycerides in the blood increase.

If triglycerides in the blood are high it is very likely that cholesterol in the blood is also high.

If triglycerides, cholesterol and calcium are accumulated in the bloodstream, it is possible that they can narrow arteries (atherosclerosis) or even cause the closure of an artery.

What is the triglycerides blood test for?

Triglycerides blood test is used as a cardiovascular risk factor.

High levels of triglycerides in the blood are related to a higher possibility to suffer a cardiovascular disease (heart attack) or a cerebrovascular disease (stroke). This risk increases in case of obesity or overweight.

Approximately, half of the people with an episode of coronary artery disease is caused by high levels of triglycerides.

Very high levels of triglycerides (over 1000 mg/dl) may be a sign of pancreatitis (inflammation of the pancreas).

Triglycerides can be lower than normal in case of an unbalanced diet with low intake of fats and carbohydrates or due to malabsorption. Since triglycerides are a type of energy storage, a low amount of triglycerides can damage the kidney or other organs if their levels are excessively low.

Which values are considered normal triglyceride levels in the blood?

The following values are considered to be normal values:

IMPORTANT: These levels are expressed in mg/dl. They are an example of a healthy man of about 45 years old with a balanced diet, no known disease and not taking any medication. The ranges can be different depending on the laboratory or on your personal circumstances.
