Complement C4a is a clinical biomarker on the Immune panel, reported in ng/mL. Standard reference range: 0–650 ng/mL. Functional (optimal) range used by integrative practitioners: 0–550 ng/mL.
What is Complement C4a?
C4a is an anaphylatoxin fragment from C4 complement cleavage; significantly elevated levels have been associated with biotoxin illness and chronic inflammatory activation.
Reference ranges
| Range type | Value (ng/mL) | Source |

How SomaVue interprets Complement C4a
SomaVue maps every result for Complement C4a against four clinical lenses — nutrient cofactors, toxin exposure, infection drivers, and circadian/hormonal context — and connects each interpretation to specific peer-reviewed citations. Pre-mapped clinical reasoning and cross-marker pattern detection are available inside the practitioner workspace.
