LAB BLOOD WORK Flashcards
PCV
% of whole blood composed of RBC
- EDTA or HEPARIN tube (anti coagulant)
- 3/4 full
- more accurate bc centrifuged
RBC
have the highest specific gravity, and gravitate bottom tube
plasma protein
same things needed as PCV
- use refractometer
- break tube just ABOVE buffy coat
- g/dl
Erythrocyte indices
classification of certain anemia
- MCV
- MCH
- MCHC
MCV
average size of erythrocyte
MCH
average weight of hemoglobin contained in average RBC
MCHC
concentration of hemoglobin in average erythrocyte
g/dl
serum
plasma from fibrin,plasma protein, has been removed
hemolysis
ruptured cel
PLASMA PROTEIN
produced primarily by liver and immune system
-liver, and kidney disease (most common)
total protein
refractometer
-very helpful hydration status
dehydrated=elevated protein
overhydrated=decreased protein
albumin
most important protein
35% - 50% of total plasma protein in most
LIVER, RENAL DISEASE
ALBUMIN
major building and tranport protein in blood
-maintain osmotic pressure in plasma
FIBRINOGEN
-synthesized 4 hepatocytes
-forms matrix of blood clot
-necessary for blood clots
inflamation, tissue damage elevate
fibrinogen
plasma only sample used
serum does not contain fibrinogen
EDTA
composition of blood
!. erythrocyte (RBC) bone marrow, HGB
carry O2 and waste from cells/tissue
2. leukocyte (WBC)
Bone marrow(stem cells) circulate blood/lymph 5 types MEN LB body army
3. thrombocyte (plates)
made by megarocyte,jagged edge clot blood
4. plasma
straw color, electrolyte, hormones
maintain PH/temp.
5. serum
plasma w/out fibrinogen NO anticoagulant,fluid on top is serum
complete blood count
CBC
doesnt measure specific organ function!
measure over all health!
degree anemia
PCV is also known as?
microhematic or hematocrit
HCT is?
also known as PCV
circulation by an automated instrument
-still get %
total protein
LIVER, break down protein
measures protein concentration in the blood -hydration status -ESTIMATE -EDTA!! PLASMA must be CLEAR!!! HIGH results=LIPEMIC
INCREASE/DECREASE in TP means?
elevated TP=dehydration
decrease TP= OVER hydration
common proteins
albumin
globuliin
fibrinogen
albumin
most important
35-50% TP in most animals
osmotic pressure
globulin
antibody production
binding molecule
