Hematology
RBC Morphology
Acanthocyte
Cell with irregular, long, asymmetrical projections
-
-
Basophilic Stippling
-
-
Coarse stippling: toxic marrow damage, thalassemias
Burr cell
Short, evenly spaced projections
-
Elliptocyte
Elongated, elliptical cell
-
Howell-Jolly body
Small, round deeply basophilic nuclear REMNANT
Hypochromia
Cells with decrease MCH (mean cell Hb), typical iron deficiency (less coloured)
-
-
Pappenheimer body
Multiply, tiny iron containing granular blue dots
-
-
-
-
-
Spherocyte
Small, round dense cell without central pallor
Schistocyte
Fragmented, irregularly shaped
Sickle cell
Curved, banana-shaped cell
-
-
-
RBC parameters
-
Red Blood Cell Count (RBC) expressed as n x 10
Mean Cellular/Corpuscle Volume (MCV)
-
Hematocrit (Hct) L/L, %
= RBC x MCV
-
-
Reticulocytes
Increase in reticulocytes in peripheral blood reflects an increase in red cell output by bone marrow
-
-
-
Blood film prep
Take from zone of morphology, just above the tail
Storage
-
Pooled platelets
22 degrees C, 5 days, constant soft aggitation
-
-
-
-
Blood Grouping Test
Red Cell Testing
-
e.g. for blood group A, red cell will react with anti A and Anti-A,B antibodies
-
-
Blood transfusion
-
-
at Hb> 10g/dL, transfusion is rarely indicated
-
In organ transplant, ABO antigens are the most important
Rh(D) -ve when giving birth to a Rh(D) +ve will start to develop antibodies to Rh(D) +ve due to exposure to the fetus' blood.
In subsequent pregnancies, this AB could cross to the baby and result in reactions -> bad for the baby
Administer Rh immune globulin to mother after first pregnancy for it to react with the Rh(D) +ve antibodies so that in subsequent pregnancies, no reactions will occur
