  1. Which type of anemia is characterized by hypersegmented neutrophils on a peripheral blood smear?

    Answer: Megaloblastic anemia

    Megaloblastic anemia (due to B12 or folate deficiency) causes hypersegmented neutrophils with 5 or more lobes.

  2. The Wintrobe hematocrit method uses a tube that is centrifuged for how long?

    Answer: 30 minutes at 3,000 rpm

    Answer: Increased immature neutrophils (bands)

    A left shift indicates the presence of increased band neutrophils or earlier precursors, often indicating severe bacterial infection.

  5. Which hemoglobin type is predominant in normal adults?
