Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Triglycerides are oily lipids carried in the blood by lipoproteins. Triglycerides are primarily carried by very low-density lipoprotein (VLDL), chylomicrons, and remnant lipoproteins. Recent evidence supports triglycerides as an independent risk factor for atherosclerotic cardiovascular disease (ASCVD). Several conditions are associated with increased plasma triglycerides, including obesity, pregnancy, physical inactivity, excess alcohol intake, kidney disease, and diabetes. Elevated triglycerides are often associated with reduced high-density lipoprotein cholesterol, insulin resistance, hypertension, fatty liver disease, and increased waist circumference. In addition to cardiovascular risk, elevated triglycerides confer a risk for acute pancreatitis.

Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

The National Lipid Association and the National Cholesterol Education Program have set the following guidelines for lipids in a context of cardiovascular risk for adults 18 years old and older:

TRIGLYCERIDES

Normal: <150 mg/dL

Borderline High: 150-199 mg/dL

High: 200-499 mg/dL

Very High: > or =500 mg/dL

 

The Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents has set the following guidelines for lipids in a context of cardiovascular risk for children 2 to 17 years old:

TRIGLYCERIDES

2-9 years:

Acceptable: <75 mg/dL

Borderline High: 75-99 mg/dL

High: > or =100 mg/dL

10-17 years:

Acceptable: <90 mg/dL

Borderline High: 90-129 mg/dL

High: > or =130 mg/dL

Reference values have not been established for patients who are younger than 24 months of age.

Interpretation
Provides information to assist in interpretation of the test results

Maintaining desirable concentrations of lipids lowers atherosclerotic cardiovascular disease (ASCVD) risk. Establishing appropriate treatment strategies and lipid goals require that blood lipid values be considered in context with other risk factors including, age, sex, smoking status, and medical history of hypertension, diabetes, and cardiovascular disease.

 

Triglycerides results of 500 mg/dL and above are severely elevated, increasing the risk of pancreatitis.

 

Triglycerides can be lowered by increasing physical activity, low-fat diet, weight loss, and/or triglyceride lowering pharmaceuticals.

Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Result can be falsely decreased in patients with elevated levels of N-acetyl-p-benzoquinone imine (NAPQI, a metabolite of acetaminophen), N-acetylcysteine (NAC), and metamizole.

 

Consuming alcohol or fatty foods 24 hours prior to specimen collection can increase triglycerides.

 

Eating a meal 12 hours prior to specimen collection can increase triglycerides.

 

Consider repeat measurement of lipids prior to initiating or changing lipid therapy.

Method Description
Describes how the test is performed and provides a method-specific reference

This test uses a lipoprotein lipase from microorganisms for the rapid and complete hydrolysis of triglycerides to glycerol followed by oxidation to dihydroxyacetone phosphate and hydrogen peroxide. The hydrogen peroxide produced then reacts with 4-aminophenazone and 4-chlorophenol under the catalytic action of peroxidase to form a red dyestuff (Trinder endpoint reaction). The color intensity of the red dyestuff formed is directly proportional to the triglyceride concentration and can be measured photometrically.(Package insert: Triglycerides.

Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
