Hematology - study of blood cells and coagulation in normal and diseased blood cells
erythrocytes- red blood cells
luekocytes- white blood cells
thrombocytes- platelets
hematopoiesis- formation of blood cells
cbc (complete blood count) - frequent blood tests ordered (cbc )
hemoglobin- a major component of rbc--serves as a transport of vehicle for oxygen and carbon dioixde in the body
hematocrit- rbc volume vs the whole blood
erythropoietin-(hormone ) hormone whihc is produced in the kidney
hemoglobinopathies- abnormal hemoglobin responsible for diseases
hypochromic - rbc lacking in hemoglobin
cyanmethemoglobin- A relatively nontoxic compound of cyanide with methemoglobin, formed when methylene blue is administered in cases of cyanide poisoning.
hemacytometer-aka (counting chmaber)- both wbc & rbc manual counts in a precise lab equipmnt which allows for excat volume of samples to be examined.
polychromatic stains - staines most commonly used to stain blood smear for routine microscopic examination. ---It contains methylene blue, a blue stain and eosin ( a red-orange stain )
eosin ( a red-orange stain ) eosin ( a red-orange stain )
polychromatic stains ( also known as ) Wrights or Giemas Stains ) polychromatic stains ( also known as ) Wrights or Giemas Stains )
neutro~phil - the common type of granulocytic white blood cell
eosin~phil - ( red-eosin ) a form of granulocytic white blood cell, --which has red-eosin stained granules in the cytoplasm.
baso~phil - (dark purple ) dark purple cytoplasic granules--least common white blood cells
an increase of Eosinophils means allergies an increase of Eosinophils means allergies
neutrophil bands- ( increase) * appendictis
neutrophil segs- (increase) * infectious disease, appendictis
Lymphocytes (increase)* viral infection
Monocytes (increase)* TB & monocytic leukemia
Eosinophils (increase)* allergic reaction, hay fever, parasite infection
Basophil (increase)* chicken pox, polycythemia vera, and ulcerative colitis
normo~cytic- normal size cell
macro~cytic- larger than normal cell
micro~cytic- smaller than normal cell
aniso~ cytosis- marked variation in size of cell
poikilo~cytosis- rbc shows variation of shape on slide
normo~chromic- rbc w/ normal hemoglobin
hypo~chromic- not enough hemoglobin [ Large pale center ]
erythro~cyte indices- 3 equations (MCV) + (MCH) + (MCHC)
erythrocyte sedimentation rate - measurement of rate that rbc settle to bottom ( called SED RATE)
impedance principle - ( resistance principle)--diluted with electrolyte solution impedance principle - ( resistance principle) diluted with electrolyte solution
Centrifugal hematology analysis- does not require a diluted sample Centrifugal hematology analysis- does not require a diluted sample
