There are a few tests we ask for when going to the doctor's.
And actually, a quick check is just C4a and TGF-Beta1. These were always covered by our insurance until insurance stopped covering EVERYTHING and became basically out of pocket because the deductibles are so high… and the doctors I see don't take insurance anyway… but that's another story. 🙂
For the details on these tests – go to the source Surviving Mold and look under Diagnosis->Lab Tests and Lab Orders.
