Leukemoid reaction is a condition characterized by an increased white blood cell count, or leukocytosis, that is caused by factors other than leukemia. It is a reactive process that can be triggered by various diseases, infections, drugs, and toxins.

Causes

The most common causes of leukemoid reactions include severe infections, malignancies, severe hemorrhage, and certain medications. Other causes can include severe physical stress, such as burns or trauma, and certain metabolic disorders.

Diagnosis

The diagnosis of a leukemoid reaction is typically made based on a complete blood count (CBC) that shows a high white blood cell count. Other tests may be performed to determine the underlying cause of the reaction.

Treatment

The treatment of a leukemoid reaction is primarily aimed at addressing the underlying cause. This may involve treating an infection, stopping a medication that is causing the reaction, or managing a metabolic disorder.
