The History of VLDL Cholesterol

American scientist John Gofman's pioneering ultracentrifugation research at Berkeley during the early 1950s first carefully classified blood lipoproteins into distinct, well-defined density-based categories, identifying VLDL as the specific "very low density" fraction responsible for carrying the majority of triglycerides circulating through the bloodstream at any given time. For decades, directly measuring VLDL required Gofman's original, considerably laborious ultracentrifugation technique, a method genuinely impractical for routine, everyday clinical laboratory use across large numbers of ordinary patients. That changed in 1972, when researcher William Friedewald published his now-famous equation for calculating LDL cholesterol, which included a simple mathematical shortcut for estimating VLDL as well, simply dividing a patient's triglyceride level by five, instantly making routine VLDL reporting practical and genuinely affordable for virtually any standard clinical laboratory.

What VLDL Cholesterol Actually Is

VLDL, or very low-density lipoprotein, is a particle specifically manufactured by the liver to transport triglycerides, the body's primary form of stored fat, out to tissues throughout the body that need energy, carrying considerably more triglyceride than cholesterol when compared directly to either LDL or HDL particles. As VLDL circulates through the bloodstream, enzymes gradually strip away its triglyceride content, and the particle progressively shrinks and transforms directly into LDL, meaning VLDL essentially functions as the direct biological precursor to LDL cholesterol itself. Because VLDL levels correlate so closely with triglyceride levels, elevated VLDL typically reflects the very same underlying causes as high triglycerides, including obesity, excess alcohol consumption, poorly controlled diabetes, and various inherited genetic lipid disorders affecting how the body metabolizes dietary fat.

How VLDL Cholesterol Is Measured

VLDL cholesterol is rarely, if ever, measured directly in routine clinical practice; instead, it's calculated using the well-known Friedewald equation, simply dividing a patient's triglyceride value by five, a formula that works reasonably well at normal triglyceride levels but grows considerably less accurate and reliable once triglycerides climb especially high. For patients with significantly elevated triglycerides, where this simple calculation becomes genuinely unreliable, some specialized laboratories instead measure VLDL directly using ultracentrifugation or advanced nuclear magnetic resonance spectroscopy techniques, though these considerably more expensive and specialized methods remain reserved mainly for complex or genuinely ambiguous clinical cases encountered occasionally. Because calculated VLDL depends entirely on an accurate triglyceride measurement, patients are generally asked to fast for at least nine to twelve hours before testing.

Scientists Behind the Science

John Gofman's foundational ultracentrifugation research in the early 1950s gave the scientific world its very first meaningful classification system for distinguishing VLDL from the other major lipoprotein particles circulating in blood, establishing essential groundwork for everything cardiovascular medicine would eventually build directly upon it. William Friedewald's elegant 1972 calculation then transformed that early scientific classification into an immediately practical, everyday clinical reality, making routine VLDL reporting accessible and affordable for ordinary laboratories everywhere almost overnight. Together, their combined contributions, separated by roughly two decades of steady scientific progress, gave modern cardiovascular medicine a genuinely complete, three-particle framework for evaluating overall cholesterol and triglyceride-related cardiovascular risk in ordinary patients.
