Morning Pseudoneutropenia

Morning pseudoneutropenia (pronunciation: morn-ing pseu-do-neu-tro-pe-nia) is a medical condition characterized by a temporary decrease in the number of neutrophils in the blood, typically observed in the morning hours.

Etymology

The term "morning pseudoneutropenia" is derived from the Greek words "pseudes" (false), "neutros" (neutral), and "penia" (poverty), indicating a false deficiency of neutral (neutrophil) cells. The prefix "morning" is added to specify the time of day when this condition is most commonly observed.

Definition

Morning pseudoneutropenia is a phenomenon where the neutrophil count in the peripheral blood is lower in the morning compared to other times of the day. This is not due to an actual decrease in the production of neutrophils, but rather a redistribution of these cells within the body.

Causes

The exact cause of morning pseudoneutropenia is not fully understood. However, it is believed to be related to the body's circadian rhythm, which regulates various physiological processes, including the distribution of white blood cells.

Related Terms
