What Do My Cholesterol Results Mean?
February 2017, Xtend-Life Expert
While booking the appointment may be a simple task, blood test results are often both daunting and confusing for many. This easy to read article covers the basics for you.
I am sure you already know that heart disease is the single biggest killer in the Western world. Recent statistics published by the American Heart Association are alarming, and although these are American figures, they are indicative of western countries whose population has a similar lifestyle and diet to the USA.
Here are some facts taken from the US 2013 statistics:
- 85.6 million Americans have one or more forms of cardiovascular disease.
- On average, around 2200 Americans die of cardiovascular disease each day.
- Cardiovascular disease is the underlying cause of 1 in every 3 deaths in the US (1 402 204 in 2013).
To put that last statistic into perspective, an additional 584 881 people died from cancer that same year, while 130 557 died from accidents.
Understand Your Risk with a Blood Test
Taking a blood test is an easy way of understanding your risk. Below is the list of the four tests for predicting your risk factors for heart disease:
- Cholesterol - both LDL and HDL
- C-Reactive Protein
There are also others such as Lipoprotein (a) and Apoliprotein A1 and B. They are useful tests if you find that your Cholesterol levels are out of line and you need additional data. Ask your physician about them if your cholesterol tests come up poor.
Note: If you are arranging these tests through your physician suggest that she/he also carries out other standard tests at the same time for Liver Function, Renal Function, carbohydrate metabolism, and if a male over 40 a PSA test and of course any other tests they may recommend.
Understanding Your Cholesterol Test Results
Many people are of the misconception that the amount of cholesterol that you have in your bloodstream is directly related to your diet. While diet is one of the factors in influencing cholesterol levels it is a relatively small one as over 80% of your blood cholesterol is manufactured by your liver.
A lot of people do not fully appreciate how essential cholesterol is for good health. It is a non-soluble waxy substance which your body needs for making hormones, cell walls and nerve sheaths. It is transported around your body in two different forms.
One form is called LDL or the 'bad' cholesterol, and the other is HDL or the 'good' cholesterol.
LDL transports the cholesterol to your cells whereas HDL travels around in your bloodstream picking up excess cholesterol and taking it back to your liver for reprocessing. Sort of like a garbage collector! Too much LDL creates the risk of clogging up your arteries which can lead to heart failure or stroke. Likewise not enough HDL will result in the same problem due to inadequate 'housekeeping'. Ideally you want your HDL score to be high and your LDL score to be low.
Total Cholesterol Levels
'Normal' - Up to 199 mg/dL
'Optimal' - Between 180 - 220 mg/dL
LDL Cholesterol Levels
'Normal' - Up to 129 mg/dL
'Optimal' - Under 100 mg/dL
HDL Cholesterol Levels
'Normal' - No lower than 40 mg/dL
'Optimal - Over 60 mg/dL
What are Triglycerides?
Triglycerides are another major risk factor in heart disease. Excess levels will thicken your blood, make it 'sludgy' which in turn leads to a risk of clotting that in turn can cause a blockage which triggers off a heart attack or stroke.
It is now believed that the triglycerides/HDL ratio is one of the most important predictors of heart disease (more accurate than the LDL/HDL ratio,) with a study showing that those with the highest ratio of triglycerides to HDL having 16 times the risk of heart attack as those with the lowest ratio of triglycerides to HDL.
'Normal' - Up to 199 mg/dL
'Optimal' - Under 150 mg/dL
Triglyceride: HDL Ratio
‘Normal’ – Anything under 3:5
‘Optimal’ – 2:1
Why C-Reactive Protein?
The presence of C-Reactive Protein in your blood indicates the presence of inflammation in your blood. Studies have shown that high levels of this inflammation is an accurate predictor of future heart problems. It was even concluded in a recent paper that CRP outperformed LDL cholesterol as a predictor of cardiovascular risk.
C-Reactive Protein Levels
'Normal' - Up to 3.0 mg/L
'Optimal' - Under 1.0 mg/L
What is Homocysteine?
Studies have established that around 10% of coronary deaths are caused as a direct result of excessive homocysteine. In these cases the victims were within the 'safe' limits of their blood lipid readings including cholesterol.
Homocysteine is an abnormal protein created by the metabolization of the amino acid methionine. In most people it is normally cleared out of the arteries quickly and is therefore not a problem... but with some people it does not and as such it should not be overlooked as it is a genuine marker of potential heart disease.
Interestingly, elevated levels of homocysteine result not from what you eat but rather from what you DON'T eat. Studies have shown that a deficiency of nutrients and in particular the B group of vitamins prevent your body from producing the enzymes needed that remove homocysteine from your blood.
'Normal' - Up to 15 micro mol/L
'Optimal' - Under 10 micro mol/L

If you haven't already, remember to get your blood levels checked. Preventing heart disease in the first place is your own responsibility, no one else's.
