Cholesterol Ratios (Cont.)

LDL/HDL Cholesterol Ratios

Another cholesterol ratio that certain labs determine is the LDL to HDL ratio. These cholesterol ratios are sometimes used to help predict the chances of developing heart disease. Such ratios compare levels of bad cholesterol (LDL) to good cholesterol (HDL). For LDL/HDL cholesterol ratios, the goal is to keep it below 3.5:1, with the ideal being under 2.5:1.
 
However, similar to the total/HDL cholesterol ratio, the medical community is divided on whether the LDL/HDL cholesterol ratio is better than absolute total cholesterol or LDL cholesterol levels in predicting a person's risk for heart disease. For treatment of high cholesterol, using the absolute numbers for LDL and HDL is recommended.
 

HDL/LDL Cholesterol Ratios

HDL/LDL cholesterol ratios compare the level of good cholesterol (HDL) to bad cholesterol (LDL). In the case of HDL/LDL cholesterol ratios, the goal is to keep this ratio above .3:1, with the ideal being above .4:1.
 

Things to Remember Regarding Cholesterol Ratios

A person may receive several cholesterol ratios with his or her cholesterol test results. However, in most cases, your healthcare provider will not use these ratios to determine if you have "healthy cholesterol." Instead, he or she will look at your LDL and HDL levels along with your other risk factors for heart disease.
