Another cholesterol ratio that certain labs determine is the LDL to HDL ratio. This ratio is also sometimes used to help predict the chances of developing heart disease. It looks at the ratio between bad cholesterol (LDL) to good cholesterol (HDL). For the LDL/HDL cholesterol ratio, the goal is to keep it below 3.5:1, with the ideal being under 2.5:1.
However, similar to the total/HDL ratio, the medical community is divided on whether the LDL/HDL cholesterol ratio is better than 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.
The HDL/LDL cholesterol ratio looks at the ratio of good cholesterol (HDL) to bad cholesterol (LDL). For the HDL/LDL ratio, the goal is to keep this ratio above .3, with the ideal HDL/LDL cholesterol ratio being above .4.
There are several ratios that a person may receive 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 along with your other heart disease risk factors.
