Phospholipid Profile (Lecithin-to-Cholesterol Ratio or Phospholipid Mass Concentration)
This test measures the concentration of phospholipids in your blood, which are essential components of cell membranes. It may be used to assess lipid metabolism or detect certain lipid disorders.

What This Test Measures
Phospholipids are a group of lipids that include lecithin and other molecules critical for cell structure and function. This test typically evaluates the mass concentration of these compounds in your blood, often as part of broader lipid or metabolic assessments.
Why It Might Be Ordered
Your healthcare provider may request this test if you have symptoms or risk factors for lipid disorders, such as high cholesterol, or if you’re undergoing evaluation for conditions like atherosclerosis, liver disease, or metabolic syndrome.
Sample Collection and Preparation
A blood sample is drawn from a vein, usually in your arm. The sample is processed to separate serum or plasma for analysis. This test does not require fasting unless specified by your provider.
Common Uses and Clinical Context
Phospholipid analysis may be used to monitor lipid metabolism, evaluate genetic disorders affecting lipid synthesis, or assess the effectiveness of treatments targeting lipid disorders.
Reference range
Adult: 2.5-4.5 mg/dLN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
