Estimate phospholipid levels using total lipids or triglyceride-based approximations for research or specialized clinical use.
The Phospholipids Calculator estimates phospholipid levels using total lipids or triglyceride values, aiding in research or evaluation of liver/metabolic disorders.
Formulas:
1. Direct Calculation (If Total Lipids Are Measured)
Phospholipids (mg/dL) = Total Lipids – Total Cholesterol – Triglycerides
2. Triglyceride-Based Estimation
Phospholipids (mg/dL) = 0.2 x Triglycerides (mg/dL)
Assumes phospholipids = 20% of triglycerides (simplified model).
🧮 Phospholipids Calculator
📐 Formulas:
This tool estimates phospholipid levels using two methods:
- Measured Total Lipids:
Phospholipids = Total Lipids − Cholesterol − Triglycerides - Triglyceride-Based Estimation:
Phospholipids = 0.2 × Triglycerides

How to Use the Calculator
- Input Values:
- Total Lipids (if available).
- Total Cholesterol (mg/dL or mmol/L).
- Triglycerides (mg/dL or mmol/L).
- Choose Formula:
- Use Formula 1 if total lipids are measured.
- Use Formula 2 for a quick triglyceride-based estimate.
Example Calculations
Formula 1 (Direct):
- Total Lipids = 600 mg/dL
- Total Cholesterol = 180 mg/dL
- Triglycerides = 150 mg/dL
Phospholipids = 600 – 180 – 150 = 270 mg/dL}
Formula 2 (Triglyceride-Based):
Phospholipids = 0.2 x 150 = 30 mg/dL
Normal Phospholipid Ranges
| Group | Phospholipids (mg/dL) | Phospholipids (mmol/L) |
|---|---|---|
| Adults | 150–300 | 3.9–7.8 |
Key Notes
- Why Estimate?
- Phospholipids are rarely measured directly in routine labs.
- Estimates help in research or specialized cases (e.g., liver disease, genetic lipid disorders).
- Triglyceride Assumption:
- Phospholipids ≈ 20–25% of triglycerides (varies by diet/metabolism).
- Unit Conversions:
The different conversion factors (38.67 for cholesterol, Total Lipids, Phospholipids and 88.5 for triglycerides) arise from the molecular weights of these lipids.
Convert mg/dL → mmol/L:
- Phospholipids (mg/dL → mmol/L): Divide by 38.67.
- Total Lipids (mg/dL → mmol/L): Divide by 38.67.
- Cholesterol (mg/dL → mmol/L): Divide by 38.67.
- Triglycerides (mg/dL → mmol/L): Divide by 88.5.
Convert mmol/L → mg/dL :
- Phospholipids (mg/dL → mmol/L): Multiply by 38.67.
- Total Lipids (mg/dL → mmol/L): Multiply by 38.67.
- Cholesterol (mg/dL → mmol/L): Multiply by 38.67.
- Triglycerides (mg/dL → mmol/L): Multiply by 88.5.
Clinical Relevance
| Phospholipid Level | Interpretation |
|---|---|
| High (>300 mg/dL) | Liver disease, cholestasis |
| Low (<150 mg/dL) | Malnutrition, malabsorption |
Limitations
- Formula 1: Requires total lipids (not standard in routine tests).
- Formula 2: Overly simplistic; accuracy decreases if triglycerides are abnormal.
- Gold Standard: Direct measurement via thin-layer chromatography (TLC) or enzymatic assays.
