LDL's are cleared by the liver. HDL is generally fatty acid poor and cholesterol ester rich. It contains a different apolipoprotein which helps the body tell it apart from LDL. Simply put, it transports cholesterol back to the liver from other areas of the body.
Another ratio is LDL/HDL. The LDL/HDL ratio is actually a purer ratio than total cholesterol/HDL, because LDL is a measure of bad' cholesterol and HDL is a measure of good cholesterol, whereas the total cholesterol is the sum of HDL, LDL, and the VLDL. Adding up the values for the HDL, LDL and VLDL makes up the total cholesterol measurement.
