Whole blood includes: erythrocytes, leukocytes, platelets, plasma
Plasma liquified portion of unclotted blood
90% water. proteins, enzymes, hormones, lipids, salts
hazy and pale yellow (all coagulation proteins)
Serum fluid that remains after coagulation has occured and clot has formed
clear, and straw colored (lacks fibrinogen group coagulation proteins)
Homeostasis The body's tendency to maintain an equilibrium, or steady state. Invitro testing
must replicate body conditions with osmotic concentration, pH, and temp
Hypotonic solution water enters cell, the cell swells, and may lyse
Hypertonic solution water leaves cell, cell may crenate
, Mean cell volume (MCV) average of volume of RBCs
MCV (fL)= Hct% x 10 / RBC count x 10^12/L
ref range: 80-100 fL
increased: megaloblastic anemia, hemolytic anemia w/ retics, liver disease, and
normal newborn
decreased: IDA, thalassemia, sideroblasti anemia, lead posioning
Mean corpuscular hemoglobin (MCH) average weight of hemoglobin in individual RBCs
ref range: 26-34 pg
MCH= Hg (g/dL) x 10 / RBC count x 10^12 / L
increased: macrocytic anemia
decreased: microcytic, hypochromic anemia
Mean corpuscular hemoglobin concentration (MCHC) average concentration of hemoglobin g/dL
ref range: 32-36 g/dL normochromic
MCHC = Hg/Hct x 100
<32 = hypochromic RBCs = IDA, and thalessemia
>36 = error in RBCs or Hg measurment or presence of spherocytes
Red cell districution width (RDW) ref range: 11.5-14.5%
high RDW: post transfusion, post treatment (ironm B12, folic acid), sideroblastic
anemia, iron and folic deficiency
Hematocrit (Hct) percentage of RBCs in a given volume of whole blood
Males: 41-53%
Females: 36-46%
Hct = MCV (fL) x RBC count (x10^12/L) / 10
Hemoglobin males: 13.5-17.5 g/dL
females: 12-16 g/dL
platelets 150-450 x 10^9/L (150,000-450,000/uL)
