A CBC shows decreased RBC, HGB, and HCT. The manual reticulocyte count result was 12%. Which of the following would you expect to see on the peripheral smear?

Remnants of DNA inside an RBC produce which type of inclusion?

How would you differentiate between an acanthocyte and an echinocyte?

The hemoglobin and hematocrit on a newborn are 18.9 g/dL and 60%. How would you interpret these data?

Which poikilocyte is indicated by the arrows in the following image?

How does the mean cell volume value classify cells?

Howell-Jolly bodies are red cell inclusions associated with what disease state?

What should be reported about the RBCs in the following image and what affect would this have on the CBC results?

Calculate the MCV from the results of a patient's CBC: RBC = 3.50 × 10¹²/L Hemoglobin = 12.0 g/dL Hematocrit = 40%

Describe the purpose of and the way to calculate the "rule of three."

Which of the following assays is not part of a typical complete blood count?

The following data were reported by an instrument: RBC = 5.00 × 10¹²/L, hemoglobin = 8.5 g/dL and hematocrit = 32%. Calculate the MCHC.

What staining method can be used to differentiate Pappenheimer bodies from reticulocytes?

An instrument printout indicates an MCV of 63 fl and an MCHC of 26 g/dl. How will the red cells appear under the microscope?
