Does anyone know the significance of gradually declining C3 and C4? My C4 has been at the very low end of normal since I started having labs drawn at the beginning of March and is now at the cutoff off being low. My C3 has also been low normal since March and is now low (decreased by 44). Does this mean anything? Waiting for other pending labs before I talk to my rheumy. I have UCTD, sicca and Raynauds.
