What does a high complement level mean?
A high complement level can indicate that your immune system's complement proteins are more active than usual. The complement system is your body's first line of defense against infections, made up of about 50 proteins that work together to fight bacteria and viruses.
In kidney diseases like C3 glomerulopathy (C3G) or immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN), doctors monitor complement levels closely. These conditions involve an overactive or imbalanced complement system that can damage your kidneys' filtering units.
Your doctor likely ordered blood tests to check specific complement proteins like C3 and C4 levels, along with complement activity tests. These help determine:
* How active your complement system is
* Whether it's contributing to kidney damage
* How well your treatment is working
It's important to discuss your specific results with your nephrologist. They can explain what your high complement level means for your particular situation and whether any treatment adjustments are needed. The complement system is complex, and interpretation depends on which specific proteins are elevated and your overall kidney function.
