Lipid Species Offer Insights Into Metabolic Health
Millions of lipid panels, blood tests that look at cholesterol levels as well as triglycerides, are performed each year, and are key to assessing risk for heart disease. New studies suggest current tests, which measure the abundance of lipid classes, are insufficient and should be replaced by tests to identify lipids at the individual species level.
