✅ Key Takeaways
What you learned: Low HDL cholesterol is associated with increased cardiovascular risk. However, high HDL is not automatically protective — the clinical significance depends on context.
An HDL result alone cannot determine cardiovascular risk. Total risk assessment, other lipid parameters, and clinical context are needed.
