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.
The target range for LDL and HDL depends on what health problems you have or risk factors. Generally, for those with low or no risk factors, your LDL should be less than 160 and HDL above 40 for males and 50 for females. If you have risk factors such as unstable angina, previous heart attacks or previous coronary artery procedures, your LDL should be below 100.
