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
