The four numbers that matter
A standard lipid profile reports four values:
- Total cholesterol — the overall amount in your blood.
- LDL ("bad") cholesterol — builds up in artery walls.
- HDL ("good") cholesterol — helps remove LDL.
- Triglycerides — a type of fat strongly linked to diet and lifestyle.
What "normal" looks like
| Marker | Healthy adult target | | --- | --- | | LDL | < 130 mg/dL (lower if high-risk) | | HDL | > 40 (men) / > 50 (women) mg/dL | | Triglycerides | < 150 mg/dL | | Total cholesterol | < 200 mg/dL |
Which number to focus on
For most adults, LDL is the single most important number. High HDL is protective; high triglycerides usually respond well to diet, exercise, and weight loss.
When to recheck
If your results are borderline, recheck in 6–12 months after lifestyle changes. If they are abnormal, your doctor may recommend medication and a recheck in 3 months.
