Read LDL, HDL and triglycerides together, with total and non-HDL cholesterol adding context. These numbers support a useful heart-health discussion when combined with family history, blood pressure and individual risk factors.
How does a lipid profile help?
The results contribute to cardiovascular risk assessment alongside medical history and examination. HDL is often called good cholesterol, but reading the full profile is more informative than selecting the most reassuring number. NHLBI explains the components of a lipid profile.
On small screens, swipe the table horizontally to read every column.
| Test | What it tells you | Read alongside |
|---|---|---|
| Total cholesterol | The total amount of cholesterol in blood. | LDL, HDL and the rest of the assessment. |
| LDL cholesterol | Cholesterol carried in LDL particles, associated with arterial buildup. | A target appropriate to individual risk. |
| HDL cholesterol | Cholesterol carried in HDL particles. | Not a complete cardiovascular risk assessment on its own. |
| Triglycerides | Another type of blood fat. | Food history, test preparation and the full panel. |
| Non-HDL cholesterol | Total cholesterol minus HDL cholesterol. | Use matching units; it is distinct from LDL. |
A simple non-HDL calculation
Suppose total cholesterol is 220 mg/dL and HDL is 50 mg/dL. Non-HDL is 220 − 50 = 170 mg/dL. This is a worked example, not a reader’s result or treatment target. Appropriate goals depend on personal risk and clinical assessment.
What do calculated and direct LDL mean?
Calculated LDL is estimated using other results in the panel. Direct LDL is measured from the blood sample. When comparing reports, check the method recorded and ask about a change in reporting. MedlinePlus explains calculated and directly measured LDL.
Preparation and follow-up
Follow instructions from the clinician and laboratory. Fasting may be requested in some circumstances, including when other tests accompany the panel. Record whether you fasted rather than assuming preparation was identical for every test.
Food choices, physical activity and avoiding smoking can contribute to lipid management. Goals and treatment decisions depend on the overall picture. Read about understanding results and health habits.
Bring four things to the discussion
- The complete profile, date and units.
- Existing blood-pressure records and health history.
- Family history of heart disease or high cholesterol.
- The questions: “Which result matters most, what is my goal, and how will we follow it?”
Frequently asked questions
Are non-HDL and LDL the same number?
No. Non-HDL is total cholesterol minus HDL. LDL is one component assessed in the lipid profile.
Should I read other results when HDL looks reassuring?
Yes. Read LDL, triglycerides and the full profile alongside risk factors rather than using HDL alone.
Does everyone need the same LDL target?
Not necessarily. Appropriate goals depend on health history and individual risk.
