What Does My Cholesterol Panel Mean?

Your doctor mentioned your cholesterol and now you are holding a report full of letters — LDL, HDL, triglycerides — with little explanation of what any of it means for you. It is unsettling to see numbers tied to your heart and not know whether they are something to worry about.

Here is what each value means and why the “good versus bad” labels exist, in plain English, so you can read your own panel with confidence.

What is cholesterol?

Cholesterol is a waxy substance your body needs to build cells and make certain hormones. The problem is balance — too much of certain types raises your risk of heart disease, because it can collect in your arteries over time. A cholesterol panel, or lipid panel, measures the different types so your provider can see where you stand.

Every value explained

Total Cholesterol
The overall amount of cholesterol in your blood. Desirable is under 200 mg/dL; borderline high is 200–239 mg/dL; high is 240 mg/dL and above.
LDL (“bad” cholesterol)
Optimal is under 100 mg/dL; near optimal is 100–129; borderline high is 130–159; high is 160–189; very high is 190 and above. It is called “bad” because it builds up in your artery walls and raises your heart-attack and stroke risk.
HDL (“good” cholesterol)
Low and risky is under 40 mg/dL for men or under 50 mg/dL for women; better is 60 and above. It is called “good” because it helps remove other cholesterol from your arteries.
Triglycerides
Normal is under 150 mg/dL; borderline high is 150–199; high is 200–499; very high is 500 and above. They are fat stored from excess calories.

The cholesterol ratio

Many providers also look at your total cholesterol to HDL ratio, which divides your total cholesterol by your HDL. It captures the balance between the cholesterol building up and the cholesterol clearing away in a single number. A ratio under 5 is good, and under 3.5 is optimal.

What affects your numbers

•Diet, especially saturated and trans fat
•Exercise and how active you are
•Genetics and family history
•Your weight
•Smoking
•Certain medications

Red flags — when to call your doctor

Most cholesterol numbers are managed over time, not in a panic. A few results, though, are worth a prompt call to your provider — especially alongside your other risk factors. Reach out about:

LDL above 190
Triglycerides above 500, which carries a risk of pancreatitis
Total cholesterol above 300
A family history of early heart disease together with high cholesterol

If you have severe symptoms such as chest pain, trouble breathing, fainting or confusion do not wait for a callback — call 911 or go to the nearest emergency room.

Questions to ask your doctor

1Which of my cholesterol numbers are outside the healthy range and by how much?
2What is my total cholesterol to HDL ratio and what does it tell us?
3Do I need to change my diet, start exercising or lose weight to improve these numbers?
4Am I a candidate for cholesterol-lowering medication, and what are the trade-offs?
5Given my family history, what is my overall heart-disease risk?
6When should I repeat this lipid panel to see if anything has changed?
