A C3 test is a blood test that measures the activity of a certain protein called Complement C3.
Understanding the C3 Test
At its core, the C3 test involves taking a blood sample. The purpose of this test is specifically to assess the function or "activity" level of the protein known as Complement C3.
This test is relevant because Complement C3 is not an isolated component in the body. It is part of a larger, complex biological mechanism.
Complement C3 and the Complement System
The protein measured by the C3 test, Complement C3, is integral to what is known as the complement system.
Based on the reference, the complement system can be understood as:
- A group of nearly 60 proteins.
- These proteins are found in blood plasma.
- They can also be located on the surface of some cells.
Therefore, the C3 test provides insight into the activity of one specific protein within this important system, which plays various roles in the body's functions.
