Hemetology Flashcards
what does CBC measure?
RBC count, RBC indices, WBC count, platelet count
what is hemoglobin measured in?
g/dL
what is hematocrit measured as?
%
what does RBC indices show?
the size and shape of cells
what does RBC indices measure?
how much hemoglobin and anemia diagnoses
what are RBC indices?
MCV, MCH, MCHC
MCV
mean corpuscular volume
what does MCV measure?
average size of RBC
how do you get the HCV?
htc/RBC (normal is 78-98)
what is HCV measured in?
femtoliters (fL)
MCH
mean corpuscular hemoglobin
what is MCH?
average amount of hemoglobin
how do you find the MCH?
hemoglobin/RBC (normal is 27-32)
what is MCH measured in?
g/dL (deciliter)
MCHC
mean corpuscular hemoglobin concentration
what does MCHC measure?
average concentration of hemoglobin per packed RBC
how do ya find MCHC?
hemoglobin/hematocrit (30-35)
what is MCHC measured in?
g/dL (deciliter)
Rule of Three
value of hct should be 3x the value of hemoglobin
wbc features
size, nuclear characteristics, cytoplasm
what means you can’t do a count?
plt clumps or fibrin
what do kids have more of than adults?
lymphocytes
normal neutrophil percentage?
50-65%
normal lymphocyte percentage?
25-40%
wbc estimate
avg x 2,000
platelet estimate
avg x 20,000
poikilocytosis
abnormal shape of rbc
anisocytosis
rbc different sizes
do red blood cells begin with a nucleus?
fuck yea my dude they do
what makes up peripheral blood?
rbc, wbc, platelets, plasma
plasma
water, electrolytes, proteins
hematopoiesis
production and maturation of peripheral blood cells
microcytic
iron deficiency anemia or thalassemia
thalassemia
too much iron
macrocytes
anemia due to B12 or folate deficiency
spherocytes
no central pallor on RBC
dole bodies
little blue spots in wbc that are a sign of infection
atypical lymphocytes
hug the rbc and look like monocytes
