Factor C assay

A Factor C assay measures the activity level of Factor C, a protein involved in the body's blood clotting process and immune response. This test helps evaluate the functionality of the complement system, which is part of your immune defense. By assessing Factor C, healthcare providers can identify certain inherited or acquired deficiencies that may increase infection risk or contribute to immune-related conditions. The procedure involves drawing a blood sample and analyzing it in a laboratory to determine how well Factor C is working, providing useful information for diagnosing immune system disorders.
