Subject: calcium levels; blood tests & terms; etc.???

I am not a vet so pull out that grain of salt, but I think that I can
help a little with parts of this.

>Hi All,

>1) What would cause calcium to be low for a few months, return to

>2) What is "hemolysis" and how does its presence affect RBC, HGB,

Hemolysis refers the rupturing of red blood cells Hemo (blood) -
lysis (destruction/dissolving).

>3) What is "polychromasia"?

Literally "many colored"; it refers to variable coloration of red blood cells.

>4) What exactly are monocytes and what causes them to become elevated?

They are manufactured by the marrow and are precursor cells of
macrophages (the "big eaters" if I recall the translation right)
which help fight disease.

>5) Do elevated lymphocytes indicate the possibility of a particular

>smoldering one) or disease is/may be present? (I hope this isn't one

I have been told in the past that either can do that.

>6) Lastly, would ingesting NutriCal a few minutes before a blood

Personal suspicion is that it could. Sugar gets picked up rapidly if
I recall right.

Again, I am not a vet, so use that grain of salt when reading this!
