What is a lipid panel?

A lipid panel is a standard blood test that measures the fats in your blood - the ones that quietly decide your heart-attack and stroke risk decades out. Four numbers come back, per MedlinePlus. Total cholesterol: the headline sum. LDL ('low-density lipoprotein') - the one to keep low: it deposits cholesterol into artery walls, building the plaques that cause heart attacks and strokes; doctors call it 'bad' cholesterol. HDL ('high-density') - the one to keep high: it ferries cholesterol back to the liver for disposal, the 'good' one. Triglycerides: a separate fat that rises with alcohol, sugar, and excess calories - high values add their own risk and, at extremes, can inflame the pancreas. How to take it: usually fasting for 9 to 12 hours (water is fine) so triglycerides read true, though many modern guidelines allow non-fasting for routine checks - ask when booking. What the numbers do: they feed a risk calculation with your age, blood pressure, and smoking status that decides whether lifestyle change alone is enough or a statin joins the plan - the panel is not a verdict, it is an input. And one number never diagnoses anything alone: trends and the whole risk picture decide. Pymander is a free AI doctor, 24/7 by text, that can walk your panel line by line.
