Final (Hematology and urinalysis) Flashcards
diapedisis
the movement of WBC out of small arterioles, venules, and capillaries as part of the inflammatory process
hemostasis
a stoppage of bleeding or of circulation
Hematopoiesis
production and development of blood cells, normally in the bone marrow
leukemia
class of hematological malignancies in which immortal clones of immature blood cells multiply at the expense of normal blood cells
anemia
a reduction in the oxygen-carrying capacity of the blood
polycythemia
many rbc’s
thrombocytosis
increase in normal platelets
leukocytosis
abnormal increase in WBC (leukocyte) count
Leukopenia
abnormal decrease in WBC (leukocyte) count
electrical impedance
a process of counting blood cells that depends on their resistance to the flow of an electrical current
spectrophotometry
a machine (or part of machine) that is used to measure how much light of a certain wavelength has been absorbed by a specimen
microcytic
small erythrocytes less than 5 u in diameter
macrocytic
abnormally large erythrocytes exceeding 10 u in diameter
normocytic
a red blood cell of normal size which is 6 to 8 albumin
albumin
plasma protein that functions as a carrier molecule for transporting various chemicals throughout the body. also functions to prevent plasma from leaking out of caterpillars. Patients with poor glycemic control may have albumin present in the urine, indicating damage to the kidneys
hemturia
presence of blood i a urine sample
olguria
low urinary output of less than 400 mL
waived testing
n
deydration
n
polyuria
excessive urine output
turbidity
n
universal precautions
the concept that all blood products and other potentially infectious material are to be treated as if they are infected with blood borne pathogens
refractometer
instrument used to determine specific gravity of a liquid regular results are 1.005-1.030
QC quality control
practices used in the lab to ensure the results for given test are accurate
