In a routine lipid assessment, which parameter is considered protective when elevated?

• A. Total Protein
• B. LDL
• C. HDL is protective when elevated
• D. Triglycerides

Answer: (C)

HDL is protective when elevated because it helps remove cholesterol from arteries and transports it to the liver for excretion (reverse cholesterol transport). It also has anti-inflammatory and antioxidant effects that reduce the risk of atherosclerosis. So, higher HDL levels are associated with lower cardiovascular risk, which makes it the protective parameter on a lipid panel. In contrast, LDL and triglycerides contribute to plaque formation or metabolic risk when elevated, and total protein isn’t a lipid measure. In practice, higher HDL is generally considered favorable, with typical targets around ≥40 mg/dL for men and ≥50 mg/dL for women.
