I've been 20-36 since 2006, when I got much iller it didn't go up at all.
It varies with everyone so there is no hard& fast rule with this, what it does show is that you have inflammation somewhere in your body.
Compounds C3&C4 are not common blood tests but they are very good inflammation markers- had mine done twice and they were massive and also increased the second time- 150-400 is the norm for one and mine came out at 680, then 750.
