What does the spleen do with the blood?
It stores and produces blood, but most importantly, removes old blood cells from circulation
What are the three types of bloodwork?
PCV, CBC and Chemistry Panel
Average percentage of blood in the PCV tube that is made of cells is?
35%-50%
What if the cells in the PCV tube are higher than 50%?
the pet is dehydrated
What if the cells in the PCV tube are lower than 50%?
the pet is anemic
What is included in a CBC?
A complete blood count includes a hematocrite but look sat the three type of cells in the blood: RBC, WBC, and platelets
Can the blood be clotted, when doing a CBC?
The blood cannot be clotted, if the cells are bound together then you can't look at them well
What keeps the blood from clotting in a lavender top tube?
EDTA (ethylenediaminetetra-acetic acid)
What can larger RBC's show in CBC?
If the cell show a larger RBC is shows its immature and is likely response to anemia
What parasite can be shown in the CBC on the RBC?
Hemobartonella
What does HGB on the erythrocyte show?
HGB is hemoglobin, and the oxygen carrying molecule with in the erythrocyte (RBC)
What does the MCHC stand for in relation to a cropuscle or erythrocyte?
Mean Corpuscular Hemoglobin Concentration
What does the MCV stand for in relation to RBCs on a CBC?
Mean Corpuscular Volume
What is the retics in relation to the corpuscle analysis in a CBC?
Reticulocytes are immature red blood cells that indicate a response by the body to anemia
Types of White Blood Cells: Neutrophils
most common type of white blood cell
Types of White Blood Cells: Bands
Immature neutrophils: their presence indicates a severe infection that requires the body to release cells before they are fully developed
Types of White Blood Cells: Eosinophils
When these cells are present in high numbers they often indicated the existence of an allergy or parasite
Types of White Blood Cells: Basophils
Least Common type of WBC
What does a chemistry panel look at?
the liquid portion of the blood, so the liquid must be separated out
When doing a Chem Panel, what can happen if you don't use a SST?
If you don't use an SST, the red blood cells will continue to use the glucose in the serum and give an artificially low glucose
What do most of the chemistry panels test require the ability to do in there test? How can this be a problem ?
Require the ability to detect a color change in the blood; If red blood cells are ruptured during the blood draw (hemolysis) then the color of the serum will be red (hemolytic) instead of the usual clear to straw color.
Color change can occur because of hemolysis in a Chem Panel, and all because of what?
If the pet have recently eaten, which causes a milky creamy appearance known as lipemia
Chem Panels: ALP (Alk Phos)
Elevation can indicate liver disease, adrenal gland disease, steroid usage, OR active bone growth in young pets
Chem Panels: ALT (Alanine Aminotransferase)
Sensitive indicator of liver damage, but doesn't indicate cause or reversibility
Chem Panels: AST (Aspartate Transferase)
Increased levels indicate liver dx or skeletal muscle damage
Chem Panels: GGT (Gamma Glutamyl Transferase)
Liver enzyme that can indicate liver disease or cortisol excess
Chem Panels: T. BILI (Total Bilirubin)
Elevations may indicate liver disease or hemolysis. Helpful in diagnosing types of anemia or bile duct disease
Chem Panels: BUN (Blood Urea Nitrogen)
An elevation indicates an increased level of metabolic waste products in the blood. Caused by kidney disease, dehydration or inability to urinate
Chem Panels: CRE (Creatinine)
This is value is more sensitive than the BUN
Chem Panels: TP (Total Protein)
Indicates hydration status as well as providing information regarding the liver, kidney, and infectious dx among others
Chem Panels: ALB (Albumin)
Serum protein that helps evaluate hydration, enteritis, hemorrhage, liver and kidney disease
Chem Panels: GLOB (Globulin)
Blood protein that often increases with chronic inflammation and certain disease status
Chem Panels: Ca (Calcium)
Abnormalities can occur with a variety of diseases including cancer and kidney disease
Chem Panels: Cl (Chloride)
This electrolyte is often lost with vomiting or Addison's disease, elevations can indicate dehydration
Chem Panels: K (Potassium)
Lost with vomiting, diarrhea or excessive urination. Increased levels are associated with kidney failure, Addison's disease, dehydration, and urinary obstruction. Very high levels can be fatal.
Chem Panels: Na (Sodium)
Electrolyte lost
Chem Panels: PHOS (Phosphorus)
Elevations associated with kidney disease, hyperthyroidism, and bleeding disorders
Chem Panels: Na:K
When this ratio is low Addison's disease is indicated
Chem Panels: AMYL (Amylase)
Elevations often associated with pancreatitis or kidney disease
Chem Panels: LIP (Lipase)
Pancreatic enzyme; may indicate pancreatitis or abnormal blood fats
Chem Panels: GLU
Glucose or blood "sugar" that is often elevated with stress or diabetes mellitus. When glucose is too low collapse and coma or possible
Chem Panels: CORT (Cortisol)
Hormone produced by the adrenal gland. Too high suggests Cushing's disease, too low suggests Addison's disease
Chem Panels: CHOL (Cholesterol)
Elevation can indicate recent meal or hyperthyroidism, liver disease, diabetes, Cushing's etc
Chem Panels: CPK (Creatine Phosphokinase)
A sensitive but not specific indicator of smooth muscle damage or atrophy
Chem Panels: Osmolality
Can help differentiate causes of low sodium, can aid in diagnosing anti-freezing poisoning
