Lanthanum Plasma Protein Electrophoresis (Lanthanum-Based Protein Fractionation)
This test measures protein distribution in your plasma using a specialized technique that separates different protein types, which can help identify abnormalities in protein composition.

What This Test Measures
The test uses a method called lanthanum-based protein fractionation to analyze the concentration and distribution of various proteins in your plasma. This helps identify shifts in protein profiles that may indicate underlying conditions affecting protein synthesis, breakdown, or transport.
Why It Might Be Ordered
Your healthcare provider may recommend this test if you have symptoms or conditions linked to abnormal protein levels, such as liver disease, kidney problems, or certain genetic disorders. It’s also used in research or specialized diagnostic scenarios where detailed protein profiling is needed.
How the Test Works
A small blood sample is drawn, and the plasma is processed through a lanthanum-based system that separates proteins based on size, charge, or other characteristics. The results provide a profile of protein fractions, which can be compared to typical patterns for evaluation.
Preparation for the Test
No special preparation is needed, but avoid heavy meals or excessive alcohol before your blood draw. Fasted samples may be preferred depending on your provider’s instructions.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal protein profiles detected by this test can signal conditions like hypoalbuminemia (low albumin), dysproteinemias (abnormal protein synthesis), or metabolic disorders. It may also help monitor treatment responses in patients with chronic conditions affecting protein metabolism.
