Frequently asked questions
Why is LDL cholesterol not enough to assess cardiovascular risk?
Why is LDL cholesterol not enough to assess cardiovascular risk?
LDL cholesterol measures the amount of cholesterol in LDL particles. Apolipoprotein B directly counts all atherogenic particles and is a better risk predictor, particularly in people with metabolic syndrome or diabetes where LDL can appear normal despite high particle numbers.
What are small dense LDL particles and why are they dangerous?
What are small dense LDL particles and why are they dangerous?
Small dense LDL particles penetrate artery walls more easily, oxidise more readily, and remain in circulation longer. They are more common in people with high triglycerides and insulin resistance — a pattern often missed by standard cholesterol panels.
What is lipoprotein(a) and should I test it?
What is lipoprotein(a) and should I test it?
Lipoprotein(a) is a genetically determined cholesterol-like particle that is an independent risk factor for heart attack and stroke. Unlike LDL, it cannot be lowered significantly by diet, exercise, or statins. Testing it once is sufficient to understand your genetic cardiovascular risk.
Do I need to fast for a cholesterol blood test?
Do I need to fast for a cholesterol blood test?
Triglycerides are significantly affected by recent food intake and require a 9 to 12 hour fast for accurate measurement. For a complete and accurate lipid panel including triglycerides, LDL calculation, and advanced subfractions, fasting is recommended.
