Lipid Profile Test: Normal Ranges, Good vs Bad Cholesterol & Ratio Guide
A Lipid Profile or Coronary Risk Panel is a quantitative measurement of specific lipoprotein fractions transporting fats through the vascular endothelium. Dyslipidemia—characterized by elevated Low-Density Lipoprotein Cholesterol (LDL-C) and Triglycerides, combined with depressed High-Density Lipoprotein (HDL-C)—is the principal driving etiology of arterial plaque accumulation (atherosclerosis), angina, coronary artery disease, and ischemic stroke.
When and Why Doctors Prescribe Lipid Profile (Cholesterol Panel)
- Assessing 10-year cardiovascular disease risk in adults aged 25 and above
- Monitoring patient efficacy on cholesterol-lowering statin therapy (Atorvastatin, Rosuvastatin)
- Baseline evaluation for individuals with hypertension, diabetes, obesity, or smoking history
- Strong family history of early heart attacks (under 50 years)
Standard Pathology Reference Range Chart
Verified clinical brackets for adults and diagnostic significance
| Test Parameter | Standard Unit | Male Normal Range | Female Normal Range |
|---|---|---|---|
| Total Cholesterol | mg/dL | < 200 (Desirable) | < 200 (Desirable) |
If High: Borderline high: 200–239; High: ≥ 240. Elevated risk of arterial plaque formation. If Low: Malnutrition, hyperthyroidism, or severe chronic liver failure. | |||
| HDL Cholesterol (High-Density / Good) | mg/dL | > 40 (Optimal > 50) | > 50 (Optimal > 60) |
If High: Protective against heart disease; transports excess peripheral cholesterol back to liver for excretion. If Low: High cardiovascular risk; commonly seen in sedentary lifestyle, smoking, obesity, and insulin resistance. | |||
| LDL Cholesterol (Low-Density / Bad) | mg/dL | < 100 (Optimal) | < 100 (Optimal) |
If High: Direct driver of coronary atherosclerosis. For high-risk diabetic/cardiac patients, target is strictly < 70 mg/dL. If Low: Rare genetic hypobetalipoproteinemia or heavy statin dosage. | |||
| Serum Triglycerides | mg/dL | < 150 (Normal) | < 150 (Normal) |
If High: 150–199: Borderline; 200–499: High; ≥ 500: Very High (Acute pancreatitis risk). Linked to high refined carb/sugar intake. If Low: Very low-fat diet, malnutrition, or hyperthyroidism. | |||
| Total Cholesterol / HDL Ratio | Ratio | < 4.5 (Optimal < 3.5) | < 4.0 (Optimal < 3.5) |
If High: Higher values correlate with heightened risk of ischemic heart disease. If Low: Lower ratio represents favorable cardiovascular protection. | |||
How to Prepare for Your Lipid Profile (Cholesterol Panel)
- 110 to 12 hours of strict fasting is mandatory. Only plain water is permitted during the fasting window.
- 2Do not consume alcohol for 72 hours prior to testing; alcohol acutely drives massive Triglyceride spikes.
- 3Maintain your normal diet for 7 days before the test — do not starve or radically alter your eating patterns.

Frequently Asked Questions (FAQs)
Can I drink tea, coffee, or milk during the 12-hour fasting window?
No. Tea, coffee, milk, or juices contain sugars and dairy fats that trigger intestinal chylomicron secretion and artificially elevate your Triglycerides and LDL values. Only plain drinking water is allowed.
What is the fastest way to raise HDL (Good Cholesterol)?
Unlike LDL which lowers with statins, raising HDL primarily requires lifestyle interventions: Regular aerobic exercise (brisk walking 30 min daily), eliminating cigarette smoking, increasing omega-3 fatty acids (flaxseeds, walnuts, fatty fish), and reducing refined sugars.
