Athanasius Kircher
worms in the blood (year?)
1657
gave an account to RBC
Anton van Leeuwenhoek (1674)
described platelets as “petites plaques”

it is polychromatic, a mixture of acid and basic dyes
Wright’s Romanowsky-type stain

What is the yellow layer on the top of centrifuged blood using non-anticoagulated tube (red top)?
serum
Blood is __% liquid and __% solid.
Liquid: 55%
Solid: 45%
What is the yellow layer on the top of centrifuged blood using a tube with anticoagulant (lavender top)?
plasma
45% of blood is composed of?
cells (buffy coat + packed rbc)
55% of blood is composed of?
plasma
Blood volume of infants

T/F : In centrifuged blood, buffy coat contains all of the blood cells.
F: RBC is not included in buffy coat, only the WBC and platelets.
T/F: RBC is the heaviest blood cell which is why it settles at the bottom?
T
it is the liquid component of blood in an anticoagulated tube
plasma

Give the basic hematological methods
a. CBC
b. Reticulocyte Count
c. Erythrocyte Sedimentation Rate
Test to check the activity of bone marrow
Reticulocyte Count
Most commonly performed test in hematology
Complete Blood Count (CBC)
check if the px has inflammation
Erythrocyte Sedimentation Rate
