blood count

Complete Blood Count:  Below is a breakdown of what the Complete Blood Count really means:

Term Definition
CBC The Complete Blood Count which includes RBC, HCT, HGB, WBC, differential, MCH, MCV, MCHC & also platelet values.
RBC The Total Red Blood cell Count, if low = anemia, if high = erythrocytosis
HGB Hemoglobin, which measures the oxygen carrying ability of the RBC
HCT Hematocrit, which measures the percentage of red blood cells in whole blood, which is also called packed cell volume (PCV).
MCV, MCH
& MCHC
The calculated the values that correlate the amount of   hemoglobin and also the size of the red blood cells.
Platelets A component of the blood clotting system.
WBC The total White Blood cell Count, which provides the   overall number of all types of WBCs, which are neutrophils, lymphocytes, monocytes,  eosinophils & basophils.  They all   play a role in inflammation and fighting infection.
Differential Quantifies the amount and relative percentage of   neutrophils, lymphocytes, monocytes, eosinophils & basophils.
Neutrophil These cells make up about 2/3 of the total WBC count.
Lymphocyte These cells make up about 1/3 of the total WBC count.  If the horse was stressed at the time of the blood collection (for example, recent excitement or exercise), this may   elevate the count.
Monocytes,
Eosinophils,
Basophils
These cells make up very low percentage on the   differential.  Elevations can indicate certain inflammatory conditions such as parasitism or allergies.

 

Chemistry ProfileBelow is a brief explanation of what the Chemistry Profile really means:

Term Definition
Chemistry Profile Is a panel of tests that analyzes organs (kidney, liver   etc.) functions.
NA Sodium. Plays a large role in water regulation.  The main source is from the diet and level   can indicate intake or possibly loss (diarrhea).
K Potassium.  Elevated   levels can be deadly!  Increases can be due to renal disease,  Addisons, HYPP   in Quarter Horses.  Low levels can be due to excessive sweating, decreased intake or loss (diarrhea).
tC02 Total bicarbonate (bicarb) level.  Increased levels indicate metabolic alkalosis.  Decreased levels indicate metabolic acidosis. It is important in the racing industry as increased levels = positive test, fines, suspensions etc.
CK Creatine kinase. A muscle enzyme, elevated with muscle   damage. It peaks 4-6 hrs. after injury. It peaks before AST.
GLU Glucose.  It can be   elevated with a recent meal, decreased with liver dysfunction or prolonged time between blood collection and analysis.
CA Calcium.  Low levels may be associated with low protein levels.
BUN Blood urea nitrogen. Levels increase with kidney disease and decreases with liver failure, low protein diet & anabolic steroid use.
CRE Creatinine.  Levels increase with kidney disease.
AST Liver and muscle enzyme – will be elevated with liver or muscle damage.  It peaks about 24 hours after injury has occurred.
TBIL Total bilirubin level.  It measures liver function.  Levels may be elevated by liver disease and anorexia (not eating).
GGT Liver enzyme, levels elevate with bile stasis, large colon obstruction.
ALB Albumin – a type of blood protein – can be decreased in   chronic liver disease, inflammation, kidney disease, intestinal malabsorption   & malnutrition.  Increased levels   indicate severe dehydration.
GLOB Globulins, a type of blood protein – often increased with   inflammation, immune-mediated disease and some neo -lasms.  Decreased levels occur with passive transfer   failure in foals, severe protein loss.
A/G Ratio Compares the ratio of the amount of albumin to globulins.
TP Total protein – measures protein in the blood – can indicate dehydration if elevated.  Levels decreases with kidney & GI disease, liver failure and starvation
