Hikers make their way up the trail to Grays Peak, located on the Continental Divide. Paired with nearby Torreys Peak, the two mountains combine for a solid 1-2 punch for a beginner looking to summit their first fourteener. (Photo: Stephen Meyers/The Coloradoan )Buy Photo.
The ratio of HDL/LDL looks at the ratio of good cholesterol (HDL) to bad cholesterol (LDL). The ratio is determined by dividing the LDL cholesterol into the HDL cholesterol. For example, if a person has an HDL cholesterol of 50 mg/dL and an LDL cholesterol of 150 mg/dL, the HDL/LDL ratio would be 0.33. The goal is to keep the ratio above 0.3, with the ideal HDL/LDL ratio being above 0.4.
Therefore, in adults, the HDL-good cholesterol/total cholesterol ratio should be higher than 0.24 (just divide your HDL level by your cholesterol). Or more precisely, the HDL/total cholesterol ratio: 0.24 or higher is considered ideal. under 0.24 - low. less than 0.10 - very dangerous.
