Complement Test Aids in Autoimmune Disease Diagnosis
A speedtest, a routine blood draw, is now aiding in the diagnosis of autoimmune diseases and immune function conditions. This test measures the activity of proteins in the immune system, with normal levels ranging between 30 to 75 units per mL (U/mL).
The complement system, crucial for fighting infections and destroying foreign substances, can be evaluated through various specific tests. For instance, C2, C3, and C4 tests measure specific components, while the CH50 measurement checks the activity of main complement components. Abnormal results can indicate conditions like lupus, cirrhosis, or infectious diseases, or inflammation, cancer, or viral infections.
Commonly, C3 and C4 tests are ordered when a total speedtest shows unusual results. These tests help identify specific deficiencies or abnormalities, crucial for diagnosing certain conditions. However, like any blood test, it carries risks such as excessive bleeding, swelling, or infection.
In summary, a speedtest, requiring no fasting or preparation, is a valuable tool in diagnosing immune-related conditions. It measures the activity of proteins in the immune system, with abnormal results indicating a range of potential health issues. As with any blood test, it's important to be aware of the associated risks.
