If you’re familiar with the title, then you know what I’m talking about
.
I’m getting a little bit dated here but let’s say up till about
eight years ago, the C4a by National Jewish labs was somewhat considered a standard amongst LLMD’s. The three different times I had mine tested was having blood drawn at a regional hospital and they sent it to that specific lab which is how it’s supposed to be done.
I don’t remember if this measured inflammation, whether it be generalized or from infection, or autoimmune, or both.
In the last five years, I’ve also seen C4, and C3 testing here and wonder what the difference is.
I wonder how C4a test and C4 test compare? If at all?
During my midpoint of tick infection treatment (2016?) my C4a was around 55,000 and it went down to normal was 1400 after antibiotics. 2019 it still remained normal around 1400. All that time my wbc count , CD57 and immune proteins stayed low, did not move which brought Drs to the Primary Immune deficiency diagnosis (under range immunoglobulins).
It would be great to test this again however, my current functional medicine doctor likes to use Labs that their clinic is more familiar with and probably has not used national Jewish Laabs, I suppose I could request it and go to the Hospital for blood draw again.
