According to my readings & experience with my doctors, just one component of the bloodwork being out-of-range (low or high, depending on what is being measured) doesn't necessarily mean action is needed.
Now if several components of the bloodwork are out-of-wack AND their is an increase in symptoms, that's when my doctors stand up and take notice and start talking about
C4, my research found places that said "C4 is commonly low in Lupus patients" -- but nothing at all about
that meaning Lupus is more active. My doctor relies more on the inflammation markers: Neutrophils, Lymphs, Monocytes, Eos, Baso; (along with symptoms) to indicate activity. And when I read my blood tests and compare them with how I feel -- well, generally the inflammation markers are correct!
So, in short, as long as you don't feel a lot different I wouldn't worry about
it, esp. if the doctors aren't worried about
Hope you feel ok!
