Optimal levels for HDL (good) cholesterol are considered 60 mg/dL and higher. Slightly less great but still good levels are between 50 and 59 mg/dL. Levels that cause concern are considered 39 mg/dL or lower for men, and 49 mg/dL or lower for women.
It is the ratio between the level of HDL-good cholesterol and total cholesterol that we need to be concerned about. 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.
