I know there are a few who tested positive for mold here. I made a post questioning the $700 Real Time Labs mold test around December / Jan.

****So, I was wondering is those that tested positive for mold ALSO tested high in the C4a test with can be used for monitoring mold and lyme.***

***Or- has mold and reads low in C4a tests- that would mean C4a is not very accurate. Drs have told me C4a is VERY accurate. ***

Those two will raise the C4a values, and was told these were accurate. Before my lyme ABX I was high in C4a, now I'm normal range. So, I should not have mold either then, and I can save $700 by not taking the Real Time Labs mold test.

(Its quite obvious that I dont 100% believe Drs opinions any more. LOL, Why should anyone?)

I don't know if this helps, but I tested with high C4a levels (more than double what they are supposed to be). But I did not test positive for mold exposure. I don't have any issues with mold.

From what I know high C4a measures inflammation in your body, doesn't necessarily mean mold exposure.

what are the symptoms of mold issues?
diagnosed October 2014. I am pretty confident that I have been infected since the summer of 2006. I also have hashimoto's/hypothyroid and SIBO.
IgM 18+ 23-25 IND 28+ 30- 31++++ 34IND 39++ 41+++ 45- 58++ 66- 83-93++
IgG 41 IND

I might not have explained this too clearly. (At least I'm consistent LOL).

1)For what its worth, I have been told by three Drs that elevated C4a is from inflammation caused by mold or lyme.

2) My c4a WAS elevated but went down to normal after lyme ABX, some lyme symptoms improved as well..

3) So if #1 ( above) is true, I should not have mold either, since my C4a in now normal.

I'm just checking with people to see if this C4a test correlates with their mold condition.- double checking what three Drs told me. Because I dont want to throw $700 away on the Real Time Mold test if I dont need to (if the C4a test really is that accurate for mold).



If your C4a is still high, you still have enough Lyme left to elevate this test. (from what I've been told).

Yep, my C4a is high because I still have very much Lyme "in me"... :)

***I really appreciate knowing about peoples experience/ accuracy of this C4a test ONLY, thus the reason for this post, thank you***

Dancingbear* -mold symptoms are another subject - start another thread maybe, it could get very LONG. There is a long over lapping list.

So far my C4A is within normal range and mold tests have been negative. But who knows.
-positive IGM Western Blot- 39, 41 in January 2014// Igenex & CDC positive 11/14
-positive ANA and very low CD57
Chronic daily headaches since 2005

I just had this test. My c4a is super high. c3a is normal. My LLMD said Lyme is "strong" in me. He used C4a all the time. He though I may have detox / mold issues too based on a couple different gene tests not c4a. There are specific separate tests for mold.

A good c4a link from big brother. It's about lyme though not mold.

Hi Astroman- I've had severe mold exposure and went to a doctor that specializes in mold. I'm trying to look through my bloodwork to see if I was tested for this. Is there possibly another name for it or is this a specific test. I was tested multiple time for "Complement C4, serum" and "Complement C3, serum". Could that be what you're referring to? Not sure because I believe these tests are related to immune function.

I have been doing the Real Time Labs tests but am not aware of a blood test that can be used in its place. My doctor also did a lot of testing thru Quest testing my antibody levels to specific types of mold - Aspergillus Fumigatus, Stachbotrys Chartarum, etc. Sure enough the molds that I was exposed to (we had done an environmental test on the house) showed high on my blood work. Those levels all went back to normal range as I treated.
Symptoms started in 2012
Discovered severe mold exposure 2012-13
Diagnosed w/ Lyme & Anaplasmosis via IGenex July 2014
Symptoms: Fatigue, migrating joint/tendon/muscle pain, constant arthritis in hands/feet
8/14: Doxy 200mg
9/14: Doxy 200mg + LB Core herbs
10/14: Omnicef 600mg+Zithromax 500mg+Plaquenil 500mg+Nystatin = started to get some relief!

Yes, its called and printed with this case type " C4a".

Its just a numerical value, which is used as a "red flag" to proceed with more specific and expensive testing if its elevated- lyme or mold.

Thanks so far everyone.

Yes I forgot to mention I had a Real time labs mold test too and I was high. I also have high c4a. My LLMD keeps on referring back to Real time labs for mold issues not the c4a. He pretty much said the exact same thing @Greenblue said that c3a c4a is related to immune function for Lyme.

Posted By : astroman - 2/14/2015 12:30 PM
I suppose most people here will have elevated C4a (with or without mold) since they have lyme. I am one of the few whose C4a is now normal. It is related to both, which can be confusing for us.

Wish there was a more affordable alternative to Real Time Labs.

From "Surviving Mold": C4a

"Normal Range: 0-2830 ng/ml

C4a has become the inflammatory marker of greatest significance looking at innate immune responses in those with exposure to Water Damaged Buildings (WDB).

The complement system is a group of proteins that move freely through your bloodstream. The proteins work with your immune system and play a role in the development of inflammation."

I hear you ... I was lucky my insurance picked up Real time labs of the very very few they did
