## Overview
C4 is essential for the activation of the classical complement pathway. Low levels of C4 can indicate conditions like systemic lupus erythematosus (SLE), immune complex diseases, or hereditary angioedema. A deficiency in C4 increases the risk of recurrent bacterial infections, particularly from encapsulated organisms like S. pneumoniae, and may lead to autoimmune diseases due to impaired immune response.

## Preparation Required
Overnight fasting is preferred.
