Your cholesterol level will be provided as a concentration of cholesterol in your blood. The number refers to milligrams of cholesterol in a deciliter of blood (mg/dL). The lab may omit the unit of measurement on your results, but this is to what the numbers refer. Your doctor will consider an LDL level lower than 100 mg/dL ideal. The complete guidelines for LDL levels, for a person with no other medical conditions, are as follows:  Ideal - Less than 100 mg/dL Near optimal/slightly elevated - 100 to 129 mg/dL Borderline high - 130 to 159 mg/dL High - 160 to 189 mg/dL Severely high - Higher than 190 mg/dL You will see a separate number that indicates your HDL measurement. Your doctor will consider an HDL of 60 mg/dL (or greater) ideal. A breakdown of HDL measurements, for a man with no other medical conditions, is as follows:  Ideal - At least 60 mg/dL Borderline risk factor for heart disease - 41 to 59 mg/dL High risk factor for heart disease - Less than 40 mg/dL Women's HDL ranges are not given here. Women should see their lab test or speak to their doctor to assess their proper ranges. Like high levels of LDL, high triglyceride levels can also increase your chances of atherosclerosis (artery narrowing and hardening), raising the risk of heart attacks and strokes. Your doctor will consider less than 150 mg/dL ideal, assuming you have no other medical conditions. The full breakdown of your triglyceride measurement is:  Ideal - Less than 150 mg/dL Elevated - 150 to 199 mg/dL High - 200 to 499 mg/dL Extremely high - Higher than 500 mg/dL Once you have these three numbers, you can use them in a simple equation to calculate your total cholesterol. The equation is:  LDL + HDL + (triglycerides/5) = total cholesterol. For instance, if you had an LDL of 100, HDL of 60, and triglyceride level of 150, then the equation would read: 100 + 60 + (150/5). With all of your numbers plugged into the equation, you can simply perform the division and addition components to reach your total cholesterol level.  For instance, calculating the previous example would be 100 + 60 + (150/5) = 100 + 60 + 30 = 190. You can also find online calculators that will tally your total cholesterol from the individual numbers. Similar to the individual components, your total cholesterol will fall into a range of readings from ideal to high. Your doctor will consider a total cholesterol reading of less than 200 mg/dL ideal, assuming you have no other medical conditions. However, the full range of readings is:  Ideal - Less than 200 mg/dL Elevated - 200 to 239 mg/dL High - 240 mg/dL or greater While total cholesterol is a useful tool to have, you should still go over the component parts with your doctor because the number can be misleading. For instance, 99 LDL + 60 HDL + (200/5 triglyceride) = 199 total cholesterol. A total cholesterol level of 199 is not cause for alarm, but 200 is high for a triglyceride reading, and your doctor would still want to discuss options to help control your triglycerides. If any of your individual readings or your total cholesterol is out of the optimal range, then your doctor will likely recommend making lifestyle changes to help reduce your cholesterol. These steps include:  Reducing saturated fats, trans fats, salt, and sugar in your diet Choosing healthy food options, such as fruits, vegetables, legumes, whole grains, and lean meat protein Getting at least thirty minutes of cardio exercise each day Quitting smoking (if applicable) Maintaining a healthy weight You can find complete information with steps for lowering your cholesterol at How to Unclog Arteries Naturally.
