Not so fast monsterof5.
You're jumping to conclusions, which are not well-founded.
Chronic or acute inflammation, Thyroiditis, Sarcoidosis,
Ulcerative colitis, Heart Attacks and other conditions will also increase your complement levels.
This result cannot indicate to your doctor what is wrong with you, only that your immune system is involved with some condition.
I suggest you discuss this with your doctor, before anxiety and stress start affecting you, in addition to any underlying issues you may have.
Best wishes,
