ApoB Test (Apolipoprotein B)
Counts the actual particles that clog arteries. Better predictor than LDL alone.
Your cholesterol panel came back fine and you still do not feel reassured, because your father had a heart attack at 52 and "fine" was not enough for him either. ApoB is the test that resolves that tension. Standard cholesterol measures how much cholesterol is being carried. ApoB counts how many particles are doing the carrying, and it is the particle count that drives plaque.
Why it matters: two people can have identical LDL numbers and very different risk, because one carries that cholesterol in many small particles and the other in few large ones. ApoB sees the difference. Major cardiology guidelines increasingly treat it as the better risk marker.
Who orders it: people with family history of early heart disease, anyone whose lipid panel looks acceptable but whose doctor still seems concerned, people on statins wanting a truer read on progress, and anyone who has heard about ApoB and cannot get their doctor to order it.
How it works: order online, walk into a test center, no appointment needed. Results post privately, usually in 1-2 business days.
Fasting: preferred, 9 to 12 hours with water.
