-
PCV/MCV
Packed cell volume/Mean corpuscular volume
-
RBC/WBC
Re/white blood corpuscle
-
-
MCHC
Mean corpuscular Hb concentration
-
EDTA
Etheylene diamine tetraacetic acid
-
MPS
Mononuclear phagocytic system
-
-
-
-
-
Penia (Thrombo, Leuko)
Reduced number (decreased thrombocytes, decreased leukocytes)
-
Volemia
Blood volume (decreased is hypo, increased is hyper)
-
DIC
Disseminated intravascular coagulation
-
vWD
von Willebrand disease
-
OSPT
One stage prothrombin time
-
APTT
Activated partial thromboplastin time
-
ACT
Activated clotting time
-
% solution
Solute in gms/100ml solution
-
Specific gravity
Weight of blood (urine)/Weight of same volume of water
-
Mole (molar mass or gram molecular weight)
Molecular weight of a substance in grams (weight of 6 x 1023 molecules)
-
Molar
No: of moles/Kg of solvent (water)
-
Molal
No: of moles/Kg of solvent (water)
-
Equivalent weight
Weight (atomic or molecular or formula)/valence
-
Conversions
- mEq/L = mmol/l x valence
- mOsm/L = mmol/L x no. of particles per molecule
-
Osmosis
Net movement of solvent across a semi-permeable membrane from a solution of lower to higher solute concentration
-
Osmole
No: of molecules in 1 mole of undissociated solute (Ex: 1 mole of NaCl = 2 osmoles)
-
Osmolarity
No: of osmoles/Kg of solvent (Plasma 290-310 mOsmol/Kg)
-
Effective osmole
Solutes that are able to effect an osmotic pressures as they can't pass through a semi-permeable membrane (eg. Glucose, NaCl)
-
Ineffective osmole
Solutes that are unable to effect an osmotic pressures as they can freely diffuse through a semi permeable membrane (eg. Urea)
-
Tonicity
Effective osmotic pressure of a solution with respect to a selectively permeable membrane
