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.
Levels of 150 to 199 is regarded as borderline high, 200 to 499 mg/dL as relatively high, and levels greater than 500 mg/dL as very high. Excess LDL is an important indicator for heart disorders.
