Mannan-Binding Lectin Pathway Function Test (C4)
About Test
The Mannan-Binding Lectin Pathway Function Test (C4) is a blood test used to evaluate the function of the mannan-binding lectin (MBL) pathway, which is one of the body's first lines of defense against invading pathogens. The test measures the level of complement component 4 (C4), which is a protein involved in the activation of the MBL pathway.
The Mannan-Binding Lectin Pathway Function Test (C4) can provide important information for a variety of medical purposes, including:
Immune system evaluation: The test can be used to assess the function of the MBL pathway and the person's overall immune system.
Infection diagnosis: The test can be used to help diagnose and monitor infections caused by bacteria, viruses, and other pathogens.
Autoimmune disease diagnosis: The test can be used to help diagnose autoimmune diseases, such as systemic lupus erythematosus, by evaluating the function of the MBL pathway.
Other Inherited diseases: The Mannan-Binding Lectin Pathway Function Test (C4) can also provide important information for the diagnosis of inherited diseases that affect the function of the MBL pathway, such as primary MBL deficiency, which can increase the risk of recurrent infections and autoimmune diseases.
It's important to note that the Mannan-Binding Lectin Pathway Function Test (C4) is just one of many tests that healthcare providers use to diagnose and monitor infections, autoimmune diseases, and other conditions. The results of this test should be interpreted in the context of a person's complete medical history, physical examination, and other relevant laboratory tests.
