Understanding your results
Cholesterol and your lipid profile, explained
6 min read · Updated 25 August 2026
A lipid profile measures the fats (lipids) circulating in your blood. It is one of the most useful windows into long-term heart health, because unhealthy lipid levels tend to build up quietly for years before they cause any symptoms. Catching a trend early is exactly the kind of thing preventive testing is for.
The main numbers
- Total cholesterol — the overall amount of cholesterol in your blood.
- LDL cholesterol — often called “bad” cholesterol; higher levels are associated with fatty build-up in arteries.
- HDL cholesterol — the “good” cholesterol that helps carry cholesterol away; here, higher is generally better.
- Triglycerides — a type of fat linked to diet, alcohol and metabolic health.
- Non-HDL and the cholesterol ratios — combinations that can predict risk better than any single number.
Why the ratio matters
Two people can have the same total cholesterol and very different risk profiles, because it depends on how that total splits between LDL and HDL. That is why clinicians look at ratios — such as total cholesterol to HDL — rather than a single figure. A lipid profile reports these together so the picture is complete.
What moves your numbers
Lipid levels respond to diet, physical activity, weight, alcohol, sleep and genetics. Because they can change with lifestyle, they are a good marker to retest on a rhythm — you can see whether a change you have made is actually working, rather than guessing.
Reading it in context
A lipid profile is most meaningful alongside your other markers — blood sugar, blood pressure, weight and family history all feed into overall cardiovascular risk. At ProGen Health a clinician reviews your lipids in that fuller context and translates them into a plan you can act on, rather than leaving you with a page of numbers.
Frequently asked questions
- Do I need to fast before a cholesterol test?
- Often yes — many labs ask for an 8–12 hour fast before a lipid profile, mainly for accurate triglycerides. ProGen Health tells you exactly what is needed for the tests you have booked before your appointment.
- Is HDL or LDL the good cholesterol?
- HDL is the “good” cholesterol — it helps remove cholesterol from your arteries, so higher is generally better. LDL is the “bad” cholesterol, where high levels are linked to fatty build-up.
- How often should I check my cholesterol?
- Because lipids respond to lifestyle and drift slowly, testing on a regular rhythm is more useful than a one-off reading. ProGen Health members test twice a year and compare each result to their own baseline.
