Haematology Flashcards
In what ways can anaemia’s be classified?
How much Hb (normochromic, hypochromic), Severity (mild, moderate, severe), Size of RBC (normocytic, microcytic, mactrocytic), Regenerative vs. Non-regenerative
What is the difference between regenerative and non-regenerative anaemia’s? Give some causes.
In regenerative, the body is generating RBC to replace. Only 2 reasons for regenerative: Haemolysis, haemorrhage. Non-regen = inflammation, chronic disease.
In an iron deficiency, how would you expect to classify the anaemia?
Hypochromic, microcytic anaemia.
What is Leukemia?
A cancer of the blood or bone marrow.
How can Leukemia’s be classified?
Acute vs. Chronic, or by cell line the cancer is derived from (myeloid or lymphoid).
Which is more common, myeloid or lymphoid leukemia’s?
Lymphoid.
What does CBC stand for?
Cell body count
What does PCV stand for? How is it measured?
Packed cell volume. Blood is centrifuged, RBC on bottom, then plasma above. Measure % of RBC in sample.
What does HGB stand for?
Total haemoglobin
What does HCT stand for?
Haematocrit
What does MCV stand for?
Mean cell volume
What does MCH stand for?
Mean cell haemoglobin
What does MCHC stand for?
Mean cell Hb concentration
What is the difference between polychromatophils and reticulocytes?
They are THE SAME, but named differently based on preparation. PC = Diff-quik or Giemsa stain. Large and blue. Reticulocyte = stained with new methylene blue, RNA precipitates.
