Triglycerides are a form of fat and a major source of energy for the body. This test measures the amount of triglycerides in the blood. Most triglycerides are found in fat (adipose) tissue, but some triglycerides circulate in the blood to provide fuel for muscles to work. After a person eats, an increased level of triglycerides is found in the blood as the body converts the energy not needed right away into fat. Triglycerides move via the blood from the gut to adipose tissue for storage. In between meals, triglycerides are released from fat tissue to be used as an energy source for the body. Most triglycerides are carried in the blood by lipoproteins called very low density lipoproteins (VLDL). High levels of triglycerides in the blood are associated with an increased risk of developing cardiovascular disease (CVD), although the reason for this is not well understood. Certain factors can contribute to high triglyceride levels and to risk of CVD, including lack of exercise, being overweight, smoking cigarettes, consuming excess alcohol, and medical conditions such as diabetes and kidney disease.

Brief Description: The Triglycerides test is a fundamental laboratory analysis that measures the levels of triglycerides—a type of fat or lipid molecule—in a patient's blood. Triglycerides are a crucial energy source for the body and are stored in fat cells. This test plays a significant role in evaluating lipid metabolism and cardiovascular risk.

Also Known As: TG Test, TRIG Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Patient should be fasting 9-12 hours

When is a Triglycerides test ordered?

For healthy adults, a lipid profile, which includes triglycerides, is advised every 4 to 6 years to assess the risk of heart disease. Between the ages of 9 and 11, as well as between 17 and 21, children should receive at least one lipid profile screening.

When persons have heart disease risk factors identified, additional testing may be required.

Triglycerides should be assessed as part of any lipid testing for diabetics because they dramatically rise when blood glucose levels are not well-controlled.

For children and young adults, screening for excessive cholesterol as part of a lipid profile is advised. Between the ages of 9 and 11, as well as between 17 and 21, they should be tested once. For children and adolescents who have a higher risk of developing heart disease as adults, earlier and more frequent screening with a lipid profile is advised. One of the risk factors includes having a family history of heart disease or having health issues like diabetes, high blood pressure, or being overweight. Other risk factors are comparable to those that affect adults.

The American Academy of Pediatrics recommends having the first cholesterol test for high-risk children between the ages of 2 and 8. Testing on children under the age of two is not appropriate.

Triglyceride tests may be requested on a regular basis as part of a lipid profile to assess the success of cholesterol-lowering lifestyle modifications like diet and exercise or to monitor the efficiency of medication therapy like statins. For people on statins, guidelines from the American College of Cardiology and the American Heart Association advise having a fasting lipid profile performed 4 to 12 weeks after beginning therapy and then every 3 to 12 months after that to ensure that the medication is effective.

What does a Triglycerides blood test check for?

Triglycerides are a type of fat and the body's main energy source. Triglyceride levels in the blood are determined by this test.

Triglycerides are primarily contained in adipose (fat) tissue, although some triglycerides also circulate in the blood to feed muscles. Triglycerides are seen in higher concentrations in the blood after eating because the body stores fat from the excess energy. Triglycerides travel from the gut to adipose tissue via the circulation to be stored there. Triglycerides are released from adipose tissue between meals and used by the body as an energy source. Very low-density lipoproteins, a type of lipoprotein, carry the majority of triglycerides in the blood.

Although the exact cause of this is unknown, high blood triglyceride levels are linked to a higher risk of cardiovascular disease development. Lack of exercise, being overweight, smoking cigarettes, drinking too much alcohol, and having medical problems like diabetes and kidney disease are just a few things that can increase triglyceride levels and increase the risk of developing cardiovascular disease.

Lab tests often ordered with a Triglycerides test:

When a Triglycerides test is ordered, it's often part of a broader evaluation of lipid metabolism and cardiovascular health. Here are some tests commonly ordered alongside it:

  1. Lipid Panel:

    • Purpose: To measure total cholesterol, LDL (low-density lipoprotein) cholesterol, HDL (high-density lipoprotein) cholesterol, and triglycerides.
    • Why Is It Ordered: To assess overall lipid status and cardiovascular risk, as a comprehensive lipid profile provides a broader picture of lipid metabolism and heart disease risk.
  2. Fasting Blood Glucose and Hemoglobin A1c (HbA1c):

    • Purpose: To measure blood sugar control over time.
    • Why Is It Ordered: To evaluate for diabetes or prediabetes, which are risk factors for cardiovascular disease and can also affect triglyceride levels.
  3. Liver Function Test:

    • Purpose: To assess liver health.
    • Why Is It Ordered: To evaluate liver function, as the liver plays a key role in lipid metabolism, and liver disorders can influence lipid levels.
  4. Kidney Function Test:

    • Purpose: To assess kidney function.
    • Why Is It Ordered: To evaluate kidney health, as kidney disease can affect lipid metabolism and increase the risk of cardiovascular disease.
  5. Thyroid Function Tests:

    • Purpose: To assess thyroid gland function.
    • Why Is It Ordered: To evaluate for hypothyroidism, which can cause elevated cholesterol and triglyceride levels.
  6. Lipoprotein (a) [Lp(a)]:

    • Purpose: To measure levels of Lp(a), a lipoprotein associated with increased cardiovascular risk.
    • Why Is It Ordered: To further assess cardiovascular risk, as Lp(a) levels can be independently predictive of heart disease.
  7. C-Reactive Protein (CRP), High-Sensitivity (hs-CRP):

    • Purpose: To detect low levels of CRP, a marker of inflammation in the body.
    • Why Is It Ordered: To evaluate systemic inflammation, which is a risk factor for cardiovascular disease.

These tests, when ordered alongside a Triglycerides test, provide a comprehensive evaluation of lipid metabolism and cardiovascular risk. They are crucial for diagnosing and managing conditions that affect triglyceride levels, such as diabetes, liver disease, kidney disease, and thyroid disorders, and for developing a personalized approach to reducing cardiovascular risk. The specific combination of tests will depend on the individual’s health status, family history, and potential risk factors for cardiovascular disease.

Conditions where a Triglycerides test is recommended:

The Triglycerides test is crucial in assessing various health conditions, including:

  1. Hyperlipidemia: Elevated triglyceride levels, along with high cholesterol levels, can contribute to hyperlipidemia—a condition characterized by abnormal lipid levels in the blood.

  2. Cardiovascular Disease: High triglycerides are a risk factor for atherosclerosis, heart disease, and stroke.

  3. Metabolic Syndrome: Metabolic syndrome, characterized by a combination of obesity, high blood pressure, elevated triglycerides, and insulin resistance, requires careful lipid profile assessment.

How does my health care provider use a Triglycerides test?

Triglyceride blood tests are typically a component of a lipid profile, which is used to determine a person's risk of developing heart disease and to assist determine what treatment may be required if there is a borderline or high risk. It can be used to monitor persons who have heart disease risk factors, those who have had a heart attack, or those who are receiving treatment for high lipid and/or high triglyceride levels as part of a lipid profile.

A treatment and follow-up plan is created using the results of the cholesterol test and other elements of the lipid profile, as well as any recognized risk factors for heart disease. Treatment options may include lipid-lowering medications like statins or lifestyle modifications like diet and exercise regimens.

What do my Triglycerides test results mean?

Healthy lipid levels generally contribute to heart health and reduce the risk of heart attack and stroke. To evaluate a person's overall risk of heart disease, if treatment is required, and, if so, which treatment will best serve to minimize the person's risk, a healthcare professional will take into account the results of each component of the lipid profile in addition to other risk factors.

Both children and adults run the risk of getting pancreatitis when triglycerides are too high. Treatment should be started as soon as possible to lower triglyceride levels.

Most Common Questions About the Triglycerides test:

Purpose and Clinical Significance

What is the Triglycerides test?

The Triglycerides test measures the amount of triglycerides, which are a type of fat (lipid), in your blood. Elevated levels can increase the risk of heart disease, especially when associated with other lipid imbalances and risk factors.

Why is the Triglycerides test important?

This test is crucial for evaluating a person's risk of developing heart disease. High levels of triglycerides, when combined with low HDL cholesterol or high LDL cholesterol, can accelerate atherosclerosis, increasing the risk of heart attacks and strokes.

Interpretation of Results

What do elevated results in the Triglycerides test indicate?

High triglyceride levels, often considered as values above 150 mg/dL, can be indicative of an increased risk of heart disease. Other conditions, like metabolic syndrome, type 2 diabetes, or hypothyroidism, can also be associated with high triglycerides.

How are the results of the Triglycerides test used in conjunction with other lipid tests?

The Triglycerides test is typically part of a lipid panel, which also measures total cholesterol, LDL cholesterol, and HDL cholesterol. The combination of these results provides a comprehensive understanding of a person's lipid profile and associated cardiovascular risk.

Disease and Complications

What conditions can cause high triglyceride levels in the Triglycerides test?

Several conditions can lead to elevated triglyceride levels, including obesity, uncontrolled diabetes, regular alcohol consumption, kidney disease, and hypothyroidism. Some medications, like beta-blockers, diuretics, and steroids, can also raise triglyceride levels.

Can diet impact the results of the Triglycerides test?

Yes, diet can significantly influence triglyceride levels. Diets high in carbohydrates, especially sugars, can elevate triglyceride levels. Conversely, diets rich in omega-3 fatty acids, like those found in fish, can lower triglyceride levels.

Relation with Other Tests

Why might a doctor order both a Triglycerides test and a cholesterol test?

Together, these tests provide a comprehensive view of a person's lipid profile, helping doctors assess cardiovascular risk better. The balance of triglycerides, LDL, and HDL is crucial in understanding the complete picture of heart health.

If triglyceride levels are elevated in the Triglycerides test, what other tests might be recommended?

If triglycerides are high, a doctor might recommend tests for blood sugar, liver function, kidney function, and thyroid function to determine if an underlying condition is causing the lipid imbalance.

Understanding the results of the Triglycerides test in the broader context of overall health and other diagnostic findings allows healthcare professionals to make informed decisions about interventions, lifestyle recommendations, and treatment options.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.
