Lab Quiz 2 Flashcards
What is the NMB staining procedure
3 drops of NMB
2 drops of blood
Mix well and have for 15 minutes
Incubate for 10 mins at 37C
Make 3 smears
Let it dry
What is not visible in a Wright stain
Reticulocytes
Heinz bodies
Hemoglobin H
Polychromasia
Basophilic stippling
Supravital stains - reticulocyte
A reticulocyte stain measures
Aggregates of residual ribosomes and mitochondria that form clumped granular material called reticulum
% retics =
(Number of retics/1000)*100
For anemia, retic index (corrected) % =
(% retics* hematocrit of patient)/ normal hematocrit (45%)
For young reticulocytes, reticulocyte production index (RPI) =
Retic index/maturation time in days
Blister cell
Bite cell
Heinz bodies
How are Heinz bodies formed
By damage to the hemoglobin component molecules, usually through oxidative damage by administered drugs, or from an inherited mutation
What are denatured Hgb due to oxidative stress
Heinz bodies
Hemoglobin H disease
Note: tear drops and blister cells
Supravital stain - hemoglobin H
Lots of Heinz bodies
Hemoglobin H is made up of
4 beta sheets
Study differences
Pappenheimar bodies
(Abnormal granules of iron)
What stain is Perl’s reaction
Prussian blue stain
What does the Prussian blue stain (perl’s reaction) demonstrate
Iron stores in bone marrow or sideroblasts on peripheral blood smear
Positive iron stain in bone marrow
Negative iron stain in bone marrow
Howell-jolly bodies
(Nuclear remnants) fragments of DNA
Cabot rings
(Remnants from a mitotic spindle)
