Describe the overall diagnostic approach.
Screening for lipid disorders
All individuals 40–75 years of age 
Patients with a family history of familial hypercholesterolemia or premature ASCVD: Consider earlier screening.
Adequate in most cases: nonfasting lipid profiles
Nonfasting triglycerides > 400 mg/dL or if evaluating for familial lipid disorders: fasting lipid profile
Assess ASCVD risk to guide treatment decisions, e.g., via the 2013 ACC/AHA pooled cohort equation
