A: Leukocytes that normally appear in the peripheral blood

B: Toxic abnormalities of neutrophils

C: Leukocytes that only appear pathologically in the  peripheral blood


A: Leukocytes that normally appear in the peripheral blood
Step 1: Examine and compare normal leukocytes
Look at the series of images of normal leukocytes. Compare the different leukocytes and try to learn their characteristics.
Step 2: Identify normal leukocytes
Name the leukocytes and immediately receive the correct term.
Step 3: Recognize normal leukocytes 
Name the leukocytes and then find out whether you are right or wrong.
Step 4: Perform leukocyte differentials
Count 100 leukocytes. Once you have finished, you can then compare your results to the correct ones. Incorrectly identified cells can be repeated. A specialist's commentary reveals the diagnosis and provides additional information.

B: Toxic abnormalities of neutrophils and monocytes
Step 1: Examine and compare toxic abnormalities of neutrophils and monocytes
Look at the series of images of toxic and normal neutrophils and monocytes. Compare them and try to learn the toxic features.
Step 2: Recognize toxic abnormalities of neutrophils and monocytes
Name the abnormalities of the neutrophils and receive immediate notification as to whether you are right or wrong. 
Step 3: Perform a leukocyte differential with toxic neutrophils and monocytes 
Count 100 leukocytes and determine whether toxic abnormalities are present. Once you are finished, you can then compare your findings with the correct ones. Incorrectly identified cells can be repeated. A specialist's commentary reveals the diagnosis and provides additional information.

C: Leukocytes that only appear pathologically in the peripheral blood
Step 1: Examine and compare pathologic and normal leukocytes
Look at the series of images of pathologic and normal leukocytes. Compare the different leukocytes and try to learn their characteristics.
Step 2: Identify pathologic and normal leukocytes
Name the leukocytes and immediately receive the correct term.
Step 3: Recognize pathologic and normal leukocytes
Name the leukocytes and receive immediate notification as to whether you are right or wrong.
Step 4: Perform leukocyte differentials with pathologic leukocytes
Count 100 leukocytes and determine if toxic abnormalities are present. Once you are finished, you can compare your findings with the correct one. Incorrectly identified cells can be repeated. A specialist's commentary reveals the diagnosis and provides additional information.
