DEAR DOCTOR K: Should I request "advanced" cholesterol testing at my next checkup?
DEAR READER: A standard cholesterol test, or lipid profile, measures levels of HDL, LDL, total cholesterol and triglycerides in the blood. So-called "advanced" cholesterol testing is a more detailed version of this test. Cholesterol is a waxy, yellowish fat. It travels through your bloodstream in tiny, protein-covered particles called lipoproteins. These particles contain cholesterol and triglycerides, a type of fat.
