Hi everyone. I got my son's result today of his lupus test and they said that he doesn't have lupus at this time. I do have a question and I hope you don't mind me asking here but you seem so imformative. His C4 level is at below 0.6. What are the normal levels and what can happen with a level this low? Thanks for reading and answering. Luke is almost 2 (Jan 13).

Hello Wendy,

I did some research online re: the levels of C4. This is what I found out.

[We asked the doctor (at our conference yesterday) your question: >>How significant are the low C4's in terms of disease activity and diagnosis?<<. And this was the answer given:

"Low C4's *can* be significant, as an indicator of disease activity. However, there is a notable percentage of the population that have *genetically* low C4. We see this in a higher percentage with people dianosed with lupus, as opposed to the general population. In some cases, the person may not have lupus--their problem may be the low C4, which can present with symptoms similar to lupus. Through special blood tests, it can be determined if the problem is low C4 or low C4 due to lupus.

"If the person does not have a genetically low C4, then having a low C4 is usually indicative of increased disease activity. A low C4, taken with abnormalities in other areas, is a more accurate indication."]

And here are the ranges that I found online:

[C3 AND C4, SERUM
ADULT: C3 83-177 MG/DL
ADULT: C4 15- 45 MG/DL
PEDIATRIC: C3 C4
AGE (MG/DL) (MG/DL)
NEWBORN 57 - 116 7 - 23
1 - 3 MOS 53 - 149 7- 28
4 - 6 MOS 62 - 175 7 - 42
7 - 9 MOS 5 - 166 10 - 37
10 - 12 MOS 73 - 180 12 - 39
1 - 2 YRS 84 - 174 12 - 40]

I hope all goes well for you and your son!

Smiles,
