Complement 4 (C4)
  • Overview

Purpose:
The Complement 4 (C4) test measures the level of C4 protein in your blood, a component of the immune system’s complement pathway. C4 plays a crucial role in the body’s defense against infections and in regulating the immune response. Abnormal C4 levels can indicate autoimmune diseases such as lupus and rheumatoid arthritis, as well as chronic inflammation or hereditary angioedema.

Components Measured:

  • Complement 4 (C4) Levels: Determines the concentration of C4 protein in the blood to assess immune system function and diagnose immune-related disorders.

Sample Type:
Blood sample (serum).

Fasting Requirements:
Fasting is not required for the C4 test. You can eat and drink normally unless advised otherwise by your healthcare provider.

Preparation:

  • Medications: Inform your healthcare provider of any medications or supplements you're taking, as certain drugs may affect C4 levels.
  • Health Conditions: Discuss any known autoimmune disorders, recent infections, or inflammation, as these factors may influence test results.

Collection Method:
A blood sample will be drawn from a vein in your arm using a sterile needle.
