Lipid Profile (Cholesterol Panel)
Also known as: Complete Lipid Profile, Cholesterol Test, Coronary Risk Panel, Lipid Panel with Ratios
Parameters Measured in the Report
A breakdown of individual biomarkers and biological reference intervals typically found in your report:
| Biomarker | Standard Range | Unit | What It Means |
|---|---|---|---|
Total Cholesterol (TC) | Desirable: < 200 Borderline: 200–239 High: ≥ 240 | mg/dL | Total amount of cholesterol contained in all circulating lipoprotein particles. |
LDL Cholesterol (Low-Density Lipoprotein ("Bad" Cholesterol)) | Optimal: < 100 Near Optimal: 100–129 Borderline: 130–159 High: ≥ 160 | mg/dL | Atherogenic particles that deposit cholesterol directly onto arterial walls, creating plaques. |
HDL Cholesterol (High-Density Lipoprotein ("Good" Cholesterol)) | Protective: ≥ 60 Acceptable: 40–59 Low (Risk Factor): < 40 (Men) / < 50 (Women) | mg/dL | Scavenger particles that carry excess cholesterol from tissues back to the liver for excretion. |
Triglycerides (TG) | Normal: < 150 Borderline: 150–199 High: 200–499 Very High: ≥ 500 | mg/dL | Circulating form of energy storage fats; high levels correlate with insulin resistance and pancreatitis. |
VLDL Cholesterol (Very Low-Density Lipoprotein) | 5–30 | mg/dL | Particles produced by the liver that carry triglycerides; precursor to LDL. |
Total Cholesterol / HDL Ratio (TC/HDL Ratio) | Optimal: < 3.5 Moderate Risk: 3.5–5.0 High Risk: > 5.0 | ratio | Mathematical ratio comparing atherogenic cholesterol burden against protective HDL. |
* Note: Reference ranges may vary slightly between testing instruments and reagent kits. Always refer to the reference interval printed on your specific pathology report.
Clinical Focus
Total Cholesterol, HDL (good cholesterol), LDL (bad cholesterol), VLDL, and Triglycerides.
Sample & Specimen
Venous blood (Serum separator SST gold/red tube)
Fasting Protocol
10 to 12 hours overnight fasting recommended for accurate triglyceride measurement.
Turnaround Time
6–12 hours (same day)
What Is This Test?
Why Did Your Doctor Order This Test?
Physicians routinely prescribe the Lipid Panel in the following clinical scenarios:
How to Prepare Before Your Test
- Fast for 10–12 hours prior to the test. Water is allowed and encouraged.
- Avoid high-fat feasts and alcohol for 24–48 hours before testing, as acute alcohol intake spikes triglycerides.
- Maintain your normal dietary routine in the weeks leading up to the test — do not crash diet right before.
Understanding Your Results
What higher or lower readings generally mean in clinical practice:
If Values Are Higher Than Normal
Elevated LDL (>160 mg/dL) and Total Cholesterol (>240 mg/dL) accelerate arterial plaque accumulation, dramatically increasing risks of heart attacks, angina, and ischemic strokes. Severely high Triglycerides (>500 mg/dL) require urgent intervention to prevent acute pancreatitis.
If Values Are Lower Than Normal
Low HDL (<40 mg/dL in men, <50 mg/dL in women) is an independent cardiovascular risk factor, often associated with a sedentary lifestyle, smoking, metabolic syndrome, and high-refined-carbohydrate diets. Very low total cholesterol (<120 mg/dL) can signal severe malabsorption or hyperthyroidism.
Frequently Asked Questions
Why is LDL called "bad" and HDL called "good"?
LDL carries cholesterol from the liver to peripheral blood vessels where it sticks to damaged artery walls, forming plaques. HDL does the reverse: it vacuums up excess cholesterol from vessel walls and carries it safely back to the liver.
Related Laboratory Tests

Intracellular contractile heart muscle proteins released into circulation during myocardial damage.
NT-proBNP (N-Terminal Pro-B-Type Natriuretic Peptide)
Circulating concentration of neurohormonal peptides released by ventricular heart muscle under mechanical strain.
