Total cholesterol level can be determined through a simple blood test, and in fact, an at-home test kit is available and can be just as accurate as the standard tests procured in a doctor's office. So how do you know if you're at risk for heart disease or blood clots from cholesterol? The first step is to know your 'number'. In other words, have your cholesterol level checked.
240 mg/dL and over - People with cholesterol levels over 240mg/dL are at increased risk for heart attack and stroke. If your cholesterol level is 240 mg/dL or greater, consult your doctor and follow his/her advice on lowering that level.
200-239 mg/dL - Consult your doctor. Your doctor will be best equipped to interpret the results and test further for LDL andHDL levels.
Less than 200 mg/dL - This is where your cholesterol level should be. Even so, to ensure that you have the right balance - more HDL than LDL cholesterol - you should follow the Guidelines for Healthy Living.
Although these levels are important guidelines, they do not give the whole picture - they are really just rough guidelines. The LDL cholesterol level is a more important indicator of overall cardiovascular health, but having your cholesterol level checked will not necessarily give you your LDL cholesterol number.
LDL Levels
Less then 130 is optimal; 130-159 is borderline, increasing your risk for heart disease; 160 or greater puts you at greater risk for heart disease.
HDL Levels
Less then 40 increases your risk for heart disease; 60 or greater decreases your risk.
Traditional cholesterol testing is a good indicator for assessing heart disease and stroke risk; however, there are many variables that can not be controlled in this traditional testing, such as genes, race, age and past medical history. A person may appear 'heart healthy', at a good weight, fit, and eating a balanced diet, and still have unacceptable cholesterol levels. On the other hand, another person may have acceptable cholesterol levels - even acceptable HDL cholesterol levels - and still be at risk for heart disease. There is still much research to be done on cholesterol and our bodies' manufacture and control of cholesterol levels.
Fortunately, there is another test available, rather than the traditional cholesterol testing, which provides a more in-depth study of cholesterol levels. This is the VAP, or Verticle Auto Profile. This test not only indicates the HDL and LDL cholesterol levels, but also provides an analysis of the many subclasses of cholesterol and it offers a more comprehensive indication of who may be at an increased risk of heart disease. In fact, statistics show that the VAP has a 90% detection rate for persons at risk for heart disease, whereas traditional cholesterol testing may miss up to 60% of the patients at risk! Please see the VAP website for more information on the importance of this test, especially for anyone at risk for heart disease, and for information on taking the VAP.
Cholesterol levels are being tested as part of regular health screening all over the world yet many people are confused by their cholesterol numbers and how they are expressed. Part of this confusion may stem from the fact that most of the cholesterol literature is coming from the United States where they still report cholesterol levels in units that are different from those used in Canada, Europe and a good portion of the rest of the developed world. So if you are looking for information to help you understand your cholesterol test results you might not be able to understand the numbers that are reported in the American literature, that includes the internet.
The United States reports cholesterol levels in mg/dl (milligrams per decilitre) of blood. The rest of the world is using the measurement called mmol (or millimoles per litre). Without going back to basic chemistry from high school, suffice it to say that they are different measurements. So is it any wonder that these two ways of expressing your cholesterol numbers are so different?
Here is how the two different systems of measurement stack up for desirable cholesterol levels.
* Total cholesterol = less than 200 mg/dL
* LDL = less than 100-129 mg/dL (below 100 is best)
* HDL = more than 40 mg/dL (greater than 60 is considered protective against heart disease)
However, as expressed in the SI units (International System of Measurement) that most of the world is using the numbers are stated differently. (You can remember which letters refer to healthy and lousy by remembering it this way...H stands for healthy lipoprotein and L stands for lousy lipoprotein.)
* Total cholesterol = less than 5.2 mmol/L
* LDL = in the range of than 2.6 - 3.3 mmol/L (less than 2.6 is best)
* HDL = in the range of more than 1 to 1.5 mmol/L (higher is better) mmol/L
Can you see the difference in how the cholesterol numbers are expressed? The difference of course is in the units that are being measured.
Think of it like metric and imperial measures. Your weight in pounds might be a three digit number but in kilograms it could be a two digit number. Same weight different measurements.
When used to determine risk of heart disease it is not the specific cholesterol levels that are analyzed but rather the ratio of HDL in your total lipid profile. This number is called the cholesterol ratio and it gives an indication of how much of your total cholesterol is the "good stuff".
The reason that the ratio is important is because the HDL (good stuff) is so beneficial that it can protect you from the effects of the LDL if it is in your body in sufficient quantities. So even if your LDL is higher that desirable levels, if the HDL is high as well, if the ratio comes within the desired range then the risk to your health is less.
The goal is to keep the cholesterol ratio below 5:1; the optimum ratio is 3.5. The cholesterol ratio comes in at the same number no matter which system of measurement is used to express the specific cholesterol levels.
The cholesterol ratio is obtained by dividing the total cholesterol number by the value given for the HDL. For example, if a person has a total cholesterol of 240 mg/dL and an HDL of 60 mg/dL, the ratio would be 4.
Using the SI system of measurement if the total cholesterol is 7.20 mmol/L and the HDL is 1.8 mmol/L the ratio is still 4.
You can see how this is a better way of understanding risk and prevents confusion that might result from not being familiar with the units that are used to express cholesterol levels.
This information is also helpful for understanding why the strategies why the for cholesterol imbalances work. Some of the best strategies are the ones that raise the HDL levels. In particular, exercise has been found to be one of the best ways to improve the cholesterol ratio because it raises HDL levels. By contrast smoking has been found to lower HDL levels so no exercise and smoking is a recipe for low HDL levels, a poor cholesterol ratio, and a higher risk of heart disease.
Cholesterol is found in every cell of the body and is essential for the maintenance of good health. Low cholesterol levels have been associated with poor health so the goal is not to eliminate or reduce cholesterol entirely but to establish the desirable levels of each type of cholesterol so that the protective benefits of the HDL can work for you in maintaining good health.
So don't get mixed up when trying to understand you cholesterol levels. No matter what way the numbers are expressed the message is the same. You want to have enough of the good stuff and not so much of the bad stuff!
