Which lipid parameter from this case is the most markedly elevated above the normal reference range?

Which lipid parameter from this case is the most markedly elevated above the normal reference range?

• A. Total cholesterol 272 mg/dL
• B. HDL cholesterol 30 mg/dL
• C. Triglycerides 250 mg/dL
• D. LDL cholesterol 102 mg/dL

Answer: (A)

Understanding lipid panels involves comparing each value to its normal reference range and spotting which one shows the largest departure. Here, total cholesterol is markedly above its typical upper limit (usually about 200 mg/dL). A value of 272 mg/dL indicates a substantial excess, standing out more than the other measurements: LDL is only slightly above its ideal range, HDL is low (not elevated), and triglycerides, while elevated, do not exceed the reference by as large a margin in this set. Because the total cholesterol shows the greatest deviation above normal, it’s the parameter that is most markedly elevated.
