What is the purpose of this test?
The Complement C4a Plasma Test measures the level of the C4a protein, which is part of your immune system's complement system. This system plays a key role in fighting infections, removing dead cells, and regulating inflammation. Abnormal levels of C4a may indicate that your body is reacting to an infection, chronic inflammation, or an autoimmune condition. Elevated levels of C4a are often linked to inflammatory diseases, such as chronic Lyme disease, chronic inflammatory response syndrome (CIRS), or autoimmune conditions like lupus.
Healthcare providers may use this test to help diagnose or monitor these inflammatory conditions, particularly when other tests or symptoms suggest immune system involvement. By assessing C4a levels, the test provides insight into how active inflammation is in your body, which can be important for guiding treatment decisions or understanding the severity of the immune response.
Who should get this test?
- Individuals with suspected autoimmune diseases like lupus
- Those experiencing chronic inflammation or persistent allergies
- People being treated for Lyme disease or other tick-borne illnesses
- Patients with symptoms of chronic inflammatory response syndrome (CIRS)
- Anyone with unexplained fatigue, muscle aches, or joint pain
- Those with recurrent or unresolved infections
When should I order the Complement C4a Plasma Test?
You should consider ordering the Complement C4a Plasma Test if you have symptoms or conditions that may be related to chronic inflammation or immune system dysfunction. Symptoms to consider:
- Unexplained fatigue or muscle pain
- Joint pain or swelling
- Ongoing allergic reactions or persistent inflammation
- Difficulty recovering from infections, such as Lyme disease
- Symptoms suggestive of autoimmune conditions, like lupus
If you experience these symptoms or are managing a condition linked to immune system activity, this test can offer valuable information to help guide your treatment and monitor your health.
