In reviewing a patient’s complete blood count (CBC) results, the nurse notes a "shift to the left." What is the significance of these results?

A.

There is an elevated number of immature thrombocytes.

B.

There is an elevated number of immature neutrophils (bands),

C.

There is an elevated number of mature neutrophils (segs)

D.

There is an elevated number of mature erythrocytes

Answer and Explanation

The Correct Answer is B

A. There is an elevated number of immature thrombocytes - Thrombocytes are platelets, and a shift to the left does not refer to these.

B. There is an elevated number of immature neutrophils (bands) - A "shift to the left" typically refers to an increase in immature neutrophils, also known as bands, in the blood. This often indicates an acute infection or inflammation as the body is producing and releasing more neutrophils to fight an infection.

C. There is an elevated number of mature neutrophils (segs) - An elevated number of mature neutrophils (segmented neutrophils) does not indicate a shift to the left. The term specifically refers to immature forms.

D. There is an elevated number of mature erythrocytes - Mature erythrocytes are red blood cells, and a shift to the left does not pertain to red blood cell counts or maturity.
