A high eosinophil count may be due to:
•Allergic disease.
•Parasite infection, such as worms.
•Certain fungus infections.
•Asthma.
•Autoimmune diseases.
•Eczema.
•Hay fever.
•Leukemia and other blood disorders
My Eosinophils are low. The value I got for EOS is 1.1%, and the normal range is 0.5-5.5%. For EOSA, my value is 0.07 (0.02-0.50 is normal).
I haven't had my B12 levels checked, but my thrombozytes are low: 139 (150-370 is normal). My hematocrit value is also slightly low: 38.0% (39.5%-50.5%).
I also have a weird finding where my total serum protein count is low: 6.1 (6.6-8.7). But the particular protein albumin is somewhat high: 66.6% (55.8%-66.1%). So my total protein count is low, but one particular protein of that total is high. I've been looking around to see if that means anything, but haven't found anything yet.
Over the last two years, my liver enzymes (AST, ALT, and AP) were slightly high, but I've recently gotten those numbers well within the normal range (by giving up alcohol and trying all sorts of supplements: protein powder, SAMe, N-acetylcysteine, and B vitamins).
I think there might be something to the histamine hypothesis. Even though my blood tests have come back (mostly) normal, I've noticed that my veins are much more dilated than they've ever been before, and I've read that histamine can do this. I've also wondered if we might be releasing bradykinin on our breath (i.e., maybe we have tissue inflammation somewhere in our bodies, e.g., intestines, and this inflammation triggers the release of bradykinin). Bradykinin can cause uncontrollable urges to cough as well.
A weird thing, though, is why this histamine, bradykinin, or whatever it is, doesn't reliably cause us to cough as well? Maybe our immune systems are built-up against our own self-produced histamine or bradykinin?
