Omega-3 Index Basic Test Capillary Blood Collection Kits
The Omega-3 Index Test is a blood test that measures the amount of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) the two main omega-3 fatty acids found in marine sources in the membranes of red blood cells (RBCs). The result is given as a percentage of total fatty acids in red blood cell membranes, which reflects your long-term omega-3 status.
🧪 What It Measures:
• EPA and DHA levels in red blood cell membranes
• Reported as a percentage (e.g., 4%, 6%, 8%)
📊 Why It Matters:
• Omega-3s are important for heart health, brain function, inflammation regulation, and cell membrane integrity.
• The test can help assess cardiovascular disease risk and guide dietary/supplement changes.
