Those with risk factors for heart disease may be screened more often. Young children may be screened if they are obese or have a family history of high triglycerides or high cholesterol. Regular screening may also be advised for older children.
Triglyceride screening is part of a fasting lipid profile blood test. It will include other measurements such as:
