Donna did a great job explaining the labs to you. You said that your C3 was out of range, like Donna said each lab has their own range. Your C3 is just barely out of range.
Normally, a person with Lupus their C3 and C4 are out of range. Plus, they are LOW by a fair amount. Like Donna said, there are 11 symptoms and you need 4 for a DX of lupus.
People can have a low C3, C4, or a postive ANA and NOT have lupus. Healthy folks can have these labs be positive and NEVER get lupus. So try not to worry over this blood test. Wait till you speak with your Dr.
My daughter has had a positive ANA. at 1:640 since she was 7, she's now 21. She still doesn't have lupus. Until she starts showing more symptoms I'm not going to worry overly about it.
I hope when you speak with your Dr all will be fine. Let's us know what they say.
