Complement Factor B present during primary activation of complement system via the alternative pathway is occuring when C3 and PFB are decreased and C4 is normal. There are two independent pathways for complement activation --- the classical system activated by immune complexes and the alternate pathway activated by bacterial cell walls ans complex polysaccharides. Porferdin Factor B is one of the alternate pathway proteins. Source: Regenstrief Institute
