Is HDL/LDL Ratio Different From LDL/HDL Ratio?

A cholesterol test report may comprise of various cholesterol ratios as well as exact HDL, LDL and total cholesterol figures. Of all the ratios present, HDL/LDL ratio and LDL/HDL ratio are two differ ones. Both of these ratios are the reciprocals of one another and this is why people often get confused among them.

Let's take a look at how these two ratios are calculated to understand the difference clearly.

How is HDL/LDL Ratio Calculated?
The HDL/LDL Ratio is calculated by dividing the LDL cholesterol in to HDL cholesterol. Here is an example to explain the HDL/LDL ratio calculation.

If a person has HDL cholesterol of 60 mg/dL and LDL cholesterol of 180 mg/dL, the HDL ratio turns out to be 1:0.3. If a person has an HDL/LDL ratio more than 0.3, it is said to be a healthy level. However, the ideal HDL/LDL ratio is 0.4. Therefore, the doctors advise the patients to maintain at least an HDL/LDL ratio above 0.3.

How is LDL/HDL Ratio Calculated?
The LDL/HDL Ratio is calculated by dividing the HDL cholesterol in to LDL cholesterol.

Considering the above stated example- if a person has HDL cholesterol of 60 mg/dL and LDL cholesterol of 180 mg/dL, the LDL/HDL ratio turns out to be 3:1. If a person has an LDL/HDL ratio lesser than 3.5:1, he is said to have a healthy level. However, the ideal HDL/LDL ratio is 2.5:1. Therefore, the doctors advise the patients to maintain at least an LDL/HDL ratio less than 3.5:1.

Thus, you may conclude that the HDL/LDL ratio and LDL/HDL are nothing but just two ways of judging your cholesterol levels by keeping one of the two as the base.

Apart from these two cholesterol ratios, the other ratios mentioned in your cholesterol test report are Total/HDL ratio and Triglycerides/HDL ratio. All these ratios are various ways to present the test results and understand them on various bases.

However, the fact can not be denied that there is a huge controversy over the use of these ratios in diagnosing the risk of heart diseases. Most of the doctors even today like to rely on absolute HDL, LDL and total cholesterol figures to prescribe a treatment and judge the various risk factors.

Further, lipid profile is generally suggested to study the risks of heart diseases and so the use of both of these ratios is very less.
