The test looks at fats like total cholesterol, triglycerides, LDL, and HDL. Each of these plays a specific role in keeping your body healthy and maintaining your energy balance. The main goal of the test is to assess your risk of heart disease, stroke, and other cardiovascular conditions. It helps your doctor determine if you need to make lifestyle changes or start treatment to manage your cholesterol levels.
Who Should Get a Cholesterol Test?
You can get a cholesterol test anytime, but how often you need it usually depends on your age and health. For people over 65, it’s recommended to check cholesterol levels once a year. If your initial results show high cholesterol, you may need to get tested more often.
You should also consider getting your cholesterol checked if:
- You have diabetes.
- You smoke.
- You have a family history of heart disease.
- You are overweight or don’t follow a healthy lifestyle (like not exercising or eating unhealthy foods).
What Does Cholesterol Test Measure?
A complete cholesterol test evaluates four types of fats in your blood. Here is a breakdown of the importance and risks of each of them.
1. Total Cholesterol:
This measures the total amount of cholesterol in your blood, including both good (HDL) and bad (LDL) cholesterol. Higher levels of total cholesterol may indicate an increased risk of heart disease.
2. Low-density lipoprotein (LDL) Cholesterol:
LDL’s main role is to carry cholesterol to different parts of your body, including the liver and cells, where it’s used to build cell walls and produce hormones. However, it’s called “bad cholesterol” for a reason.
Too much LDL in your blood can deposit excess cholesterol in your arteries, leading to plaque buildup. Over time, this can block blood flow and increase the risk of heart attacks or strokes.
3. High-density lipoprotein (HDL) Cholesterol:
You can think of HDL as a clean-up crew that takes care of the traces left by LDL. The right amount of HDL helps keep LDL levels in check, reducing the risk of heart disease. However, having too little HDL increases the risk, and surprisingly, having too much can also be harmful. Excess HDL doesn’t always mean better protection—it can sometimes work against your body and lead to inflammation.
4. Triglycerides:
Triglycerides are fats your body creates when you consume more calories than you burn. They are stored in fat cells to provide energy when needed. High triglyceride levels are often linked to excess weight, poor diet, lack of physical activity, or conditions like diabetes. Elevated triglycerides can increase the risk of heart disease and other cardiovascular issues.
Does the Cholesterol Test Require Fasting?
According to the European Heart Journal:
Non-fasting cholesterol tests give results that are very similar to fasting tests. For most people, eating before the test causes only small changes, like a slight increase in triglycerides or a small drop in LDL cholesterol. These differences don’t have much impact on checking your heart health or deciding on treatment. That’s why both fasting and non-fasting tests are equally good at predicting heart disease risk.
Fasting will be required if;
Your non-fasting test shows very high triglycerides (above 5 mmol/L or 440 mg/dL). In that case, your doctor will ask you to fast to confirm the test results.
How Cholesterol Test is Done?
Is Cholesterol Test Covered by OHIP?
OHIP covers all the tests that are deemed medically necessary, including cholesterol tests. Some conditions that apply are;
- Tests must be mandatory for diagnosis or treatment.
- A doctor or nurse practitioner must order the test.
- It must be done at an approved location like a hospital or community lab.
If you get a cholesterol test on your own it likely won’t be covered. Check with your doctor or insurance provider to confirm what’s included.

FAQ’s
1. How do I check my cholesterol at home?
To check your cholesterol at home, you’ll need a cholesterol test kit. Start by pricking your finger with the lancet provided in the kit, then place a drop of blood onto the test strip. The test strip contains chemicals that react with your blood and change color. You can read the results by comparing the color of the strip to the guide provided in the kit. For more accurate and reliable results, it’s a good idea to cross-check them with your doctor.
2. What is a good cholesterol level for seniors?
In Canada, cholesterol levels are measured in millimoles per liter (mmol/L). For adults, including seniors, desirable levels are generally:
- Total Cholesterol: Less than 5.2 millimoles per litre (mmol/L)
- LDL (Bad) Cholesterol: Less than 2.0 mmol/L
- HDL (Good) Cholesterol) 1.3 mmol/L or higher for women; 1.0 mmol/L or higher for men
