Cholesterol Profile (Standard Lipid Panel)#

Plain-language guide to the standard cholesterol (lipid) panel - what each value means, who should test, how to prepare, and how often to retest under current Canadian guidelines.

A cholesterol profile (also called a lipid panel) is a blood test that measures the main types of fat circulating in your blood. It is one of the most important tests for estimating your risk of heart attack and stroke over the next 10 years.

What this test measures#

A standard lipid panel reports four values, plus one or two calculated ratios.

Component What it tells you Typical desirable range (adult, Canadian SI units)
Total cholesterol Sum of all cholesterol carried in the blood Below 5.2 mmol/L
LDL cholesterol ("bad cholesterol") Cholesterol on particles that deposit in artery walls and cause plaque Below 3.5 mmol/L (lower if you have higher cardiovascular risk)
HDL cholesterol ("good cholesterol") Cholesterol on particles that remove fat from artery walls Above 1.0 mmol/L (men); above 1.3 mmol/L (women)
Triglycerides Free-floating fat in the blood, mostly from food Below 1.7 mmol/L
Non-HDL cholesterol (calculated: total minus HDL) All the "bad" cholesterol-carrying particles combined Below 4.2 mmol/L
Total cholesterol / HDL ratio A rough overall risk indicator Below 4.0

Reference ranges differ slightly by lab - use the reference range printed on YOUR result, not generic numbers.


Who should consider testing#

The Canadian Cardiovascular Society (CCS) 2021 guidelines recommend a lipid panel:

  • All men starting at age 40
  • All women starting at age 40 (or at menopause if earlier)
  • Anyone with any of the following risk factors, at any age:
    • Diabetes or prediabetes
    • High blood pressure
    • Family history of early heart disease (heart attack or stroke before age 55 in a male relative or before age 65 in a female relative)
    • Family history of high cholesterol (familial hypercholesterolemia)
    • Current smoker
    • Obesity (BMI above 30)
    • Chronic kidney disease
    • Inflammatory conditions (rheumatoid arthritis, psoriasis, lupus, inflammatory bowel disease, HIV)
    • History of an aortic aneurysm
    • Chronic obstructive pulmonary disease (COPD)
    • Erectile dysfunction (a marker of vascular disease in men)
  • Anyone already on cholesterol-lowering medication who needs follow-up monitoring

Lipid panels are also recommended as part of metabolic syndrome assessment and after any new cardiovascular diagnosis.


How to prepare#

The CCS updated its guidance in 2016, and fasting is no longer required for routine lipid screening in most adults. Total cholesterol, HDL, and LDL change very little after a meal. Triglycerides do rise after eating but stay clinically useful unless they are extremely elevated.

  • For routine screening: no fasting needed - eat normally and test any time of day.
  • If your triglycerides are known to be very high (over 4.5 mmol/L) and your clinician wants the most accurate triglyceride and LDL values: fast for 9 to 12 hours.
  • Avoid heavy alcohol use for 24 to 48 hours before the test - it can elevate triglycerides.

If you've been sick, had a recent surgery, or had a heart attack within the last 6 to 8 weeks, your lipid panel may not reflect your usual values. Wait until you have recovered and discuss timing with your clinician.


How to interpret your result#

Cholesterol numbers are interpreted in the context of your overall cardiovascular risk, not just compared to a generic target. The CCS uses a 10-year cardiovascular risk estimate (FRS - Framingham Risk Score) to set personalized LDL targets.

Risk category Suggested LDL target Suggested non-HDL target Suggested ApoB target
Low risk (10-year risk under 10%) Lifestyle first; medication only if very high LDL - -
Intermediate risk (10 to 19.9%) Below 2.0 mmol/L if treatment offered Below 2.6 mmol/L Below 0.8 g/L
High risk (20% or higher) Below 2.0 mmol/L Below 2.6 mmol/L Below 0.8 g/L
Statin-indicated condition (existing heart disease, diabetes with risk factors, chronic kidney disease, abdominal aortic aneurysm, LDL above 5.0 mmol/L) Below 1.8 mmol/L Below 2.4 mmol/L Below 0.7 g/L

The CCS has increasingly emphasized non-HDL cholesterol and apolipoprotein B (ApoB) as better measures of risk than LDL alone, especially in people with high triglycerides, diabetes, or obesity. See the NMR Lipid Profile page for ApoB and other advanced measures.


What does an abnormal result mean?#

I was placed in a "low-risk treatment group". What does that mean?#

The clinician reviewed your full lipid profile and risk factors (age, blood pressure, diabetes status, smoking, family history) and concluded that cholesterol-lowering medication is not needed right now.

Recommended approach in the low-risk group is lifestyle improvement, not medication:

  • Exercise: 30 minutes of moderate activity at least 5 days per week (brisk walking, cycling, swimming).
  • Mediterranean-style eating: plenty of vegetables, fruit, whole grains, legumes, nuts; olive oil instead of butter; fish and lean poultry more often; less red meat and processed food.

A repeat lipid panel in 12 months is the typical follow-up.

My LDL is high but my HDL is also high. Is that protective?#

A high HDL was traditionally considered protective, but recent evidence is more nuanced. Very high HDL (above 2.5 mmol/L) does not appear to provide additional benefit and may even be associated with increased risk in some studies. Clinicians now focus more on lowering LDL, ApoB, and non-HDL rather than chasing higher HDL. Lifestyle improvements (exercise, weight loss, less refined carbohydrate) raise HDL modestly. There is no medication routinely prescribed to raise HDL.

My triglycerides are high but my LDL is normal. What does this mean?#

High triglycerides (above 1.7 mmol/L) usually point to:

  • Diet high in refined carbohydrates, sugar, or alcohol
  • Excess body weight, particularly abdominal
  • Prediabetes or diabetes
  • Hypothyroidism
  • Some kidney and liver conditions
  • Certain medications (steroid pills, some diuretics, hormonal medications, some HIV medications)

Triglycerides above 4.5 mmol/L need careful follow-up because they can affect pancreas health. Triglycerides above 10 mmol/L are a medical urgency - please contact a clinician or urgent care promptly.

Can my cholesterol be falsely high or low?#

Cholesterol levels fluctuate by 5 to 10% even in the same person from week to week. Single measurements can be misleading for several reasons:

  • Acute illness, infection, or surgery in the past 6 to 8 weeks can temporarily lower cholesterol.
  • Pregnancy raises lipids substantially - screening is generally deferred until at least 3 months postpartum.
  • Recent heavy alcohol use raises triglycerides.
  • Inadequate fasting (if your lab still asks for fasting) can raise triglycerides.
  • Lab variability - the same blood sample tested twice can give slightly different numbers.

Repeat testing in 4 to 12 weeks is reasonable for borderline results before making treatment decisions.

Does diet really matter, or is cholesterol mostly genetic?#

Both. Genetics set the baseline (some people make a lot of cholesterol in the liver regardless of diet), but diet, exercise, weight, and smoking shift the number meaningfully. Most people see LDL changes of 5 to 15% with diet and exercise alone. Familial hypercholesterolemia - an inherited form with very high LDL from childhood - usually requires medication regardless of lifestyle.

What medications can raise cholesterol or triglycerides?#

Some prescription medications increase cholesterol or triglycerides as a side effect. Common ones:

  • Steroid pills (often used for autoimmune diseases)
  • Certain antipsychotic medications
  • Some immune-suppressing medications used after organ transplant
  • Some anti-HIV combination medications
  • Certain diuretics ("water pills") and beta-blockers
  • Hormonal medications, including some birth-control pills and some testosterone preparations

If you are on one of these and your lipid panel is abnormal, the clinician will weigh whether your other medication can be adjusted, whether cholesterol-lowering treatment is appropriate, or both.

What if I have a strong family history of early heart attack or stroke?#

A family history of early cardiovascular disease (heart attack or stroke before age 55 in a male relative or before age 65 in a female relative) raises your risk independently of your current numbers. In this situation:

  • Screening earlier than age 40 is reasonable.
  • The clinician may use a lower LDL treatment target.
  • Consider one-time testing of lipoprotein(a) (Lp(a)) - see the NMR Lipid Profile page.
  • Consider screening for familial hypercholesterolemia if your LDL is very high (above 5.0 mmol/L).
Should I test ApoB or Lp(a) too?#

ApoB and Lp(a) are advanced lipid measures that the CCS now recommends in specific situations:

  • ApoB: considered an alternative to LDL, and may be more accurate in people with high triglycerides, diabetes, or obesity. Some clinicians use ApoB instead of LDL for treatment decisions.
  • Lp(a): a genetically determined particle linked to higher heart disease risk. CCS 2021 recommends a once-in-a-lifetime Lp(a) measurement in adults, especially those with a family history of early heart disease. The level is largely set by genetics and does not change much with diet or most medications.

See the NMR Lipid Profile page for more on ApoB, Lp(a), and particle-based testing.

I'm already on cholesterol-lowering medication. How often should I retest?#

After starting a statin-class medication or other cholesterol-lowering medication, a follow-up lipid panel at 8 to 12 weeks tells your clinician whether the medication is working and at the right dose. Once your numbers are stable on therapy, annual retesting is typically sufficient.

My doctor in the past ordered this as insured but TeleTest is asking me to pay. Why?#

In the past, some clinicians ordered tests as insured (paid by the provincial plan) when strict criteria were not met. Provinces audit clinicians to ensure publicly funded resources are used per the rules. TeleTest follows provincial coverage rules carefully so we can continue offering care. If you do not meet insured-screening criteria, you can pay through TeleTest's partner labs to access the test.

Can I be screened every year if I want to?#

Insured cholesterol screening under provincial plans is typically once every 5 years if you are low risk and well, more often if you have risk factors or are on treatment. If you want more frequent testing, you can pay out of pocket through TeleTest's partner labs at any interval.

What if I'm pregnant or recently gave birth?#

Cholesterol rises substantially in pregnancy as part of normal physiology and is not interpretable against standard reference ranges. Routine lipid screening is generally deferred until at least 3 months after delivery (or longer if breastfeeding). If you have a known severe lipid disorder, your obstetrician or maternal-fetal-medicine team will manage that during pregnancy.

What about kids and teens?#

Routine cholesterol screening is not recommended in healthy children. However, children with a strong family history of early heart disease or familial hypercholesterolemia should be screened, usually between ages 9 and 11 with a follow-up between 17 and 21. TeleTest does not currently provide pediatric care - please see a family doctor or pediatrician.


Retesting and follow-up#

Situation Suggested retesting cadence
Normal screen, no risk factors Every 5 years
Borderline result 6 to 12 months
New risk factor (diabetes, hypertension, etc.) Within 12 months
Just started cholesterol-lowering medication 8 to 12 weeks, then annually once stable
On stable cholesterol-lowering therapy Annually
Strong family history of early heart disease At least every 2 years

Cost and coverage#

  • TeleTest consultation fee: out of pocket.
  • Standard lipid panel (total cholesterol, LDL, HDL, triglycerides, non-HDL): typically covered under your provincial health plan when you meet age- or risk-based eligibility criteria. If you do not qualify, you can pay through TeleTest's partner labs.
  • ApoB: generally not insured as a stand-alone test in most provinces - usually self-pay.
  • Lp(a): usually self-pay for once-in-a-lifetime testing.

When you go for your lab draw, ask the lab technician to confirm no "carbon copy" of the result is being sent to another clinician. Present only the TeleTest requisition - combining two requisitions at the same visit can route results to the wrong place.
