LDL Cholesterol Calc – How to come up with that!?

It is important for you to know how to perform LDL cholesterol calc. LDL, or low-density lipoprotein, is also known as “bad” cholesterol because it is associated with number of serious health problems including heart disease.

Good or Bad? Check your LDL Cholesterol Level:    mg/dl

If your LDL cholesterol levels are too high, it will slowly and steadily start accumulating within the walls of your blood vessels including those supplying your brain and heart.

As time passes, LDL cholesterol combines with other similar substances and starts making a hard plaque inside your arteries. Once the plaque takes its shape, there is always a chance of its breaking up from the walls of your arteries and acts like a clot and clogging your artery.

Now if such clot formations occurs within your arteries supplying your brain or heart, you will be having high chances of developing stroke or heart attack respectively due to blockage of blood supply to these vital organs.

Here are few tips to LDL calculation:

1. You will need to have your lipid panel performed at some laboratory. For your lipid panel, you will need to fast for at least 12 hours before someone takes your blood sample out for testing.

Therefore, you will be suggested not to take anything during this 12 hour fasting period including tea, and coffee.

2. Your sample will then be subjected to testing, and your cholesterol levels will be measures as number of milligram or mg per deciliter (dL). This is why you see mg/dL unit mentioned along with your cholesterol level values.


Your lipid panel test report will mention the values of your overall cholesterol levels present in your blood. Such values include the concentrations of your HDL or “good” cholesterol levels, your triglycerides, and LDL cholesterol levels too. You will need to perform LDL calculation in order to determine your LDL cholesterol levels.

4. As your LDL cholesterol levels are strongly associated with your triglycerides levels, the values of your triglycerides count a lot for calculating LDL cholesterol. If your triglycerides level turns out to be less than 400 mg/dL, all you need a simple equation to get the value of your LDL cholesterol.


However, if you have triglycerides concentrations above 400 mg/dL, your healthcare professional will recommend further laboratory testing in order to perform your LDL cholesterol calc.

5. If your triglycerides levels are below 400 mg/dL, all you need is to divide your triglycerides value by 5 and add the answer to your HDL cholesterol level.

6. In next step, you need to subtract the sum of your triglycerides and HDL cholesterol from your total cholesterol value.

7. Now LDL cholesterol Calc becomes simple. The answer is your LDL cholesterol value. You need a reference value to determine if your LDL cholesterol levels are normal or not. Usually LDL levels below 100 mg/dL are considered to be normal and anything above 186 mg/dL is considered too high.
