Factor H (FH) is a soluble glycoprotein and a member of the regulators of complement activation (RCA) family. It functions as a complement control protein and plays a critical role in regulating the complement system, particularly the alternative pathway. Factor H is a large molecule with a molecular weight of approximately 155 kilodaltons and circulates in human blood plasma at concentrations typically ranging from 200–300 micrograms per milliliter.^[5]^[6]^[7]
