The Cholesterol/HDL Ratio test measures the ratio between total cholesterol and high-density lipoprotein (HDL) cholesterol in the blood. HDL is often referred to as “good cholesterol” because it helps remove excess cholesterol from the bloodstream. A lower ratio indicates a lower risk of heart disease, while a higher ratio may suggest an increased risk. This test is used to assess cardiovascular health and to help identify individuals at higher risk for heart-related conditions. It is typically used alongside other lipid tests as part of a routine health screening.
