Differential white blood cell count, also known as a leukocyte count, is a crucial test to determine the different types of white blood cells present in the blood. The cells are classified into granulocytes (neutrophils, eosinophils, basophils) and agranulocytes (lymphocytes, monocytes). Blood smear

White blood cells, specifically neutrophils and macrophages, play crucial roles in defending the body against infections. Neutrophils attack and destroy bacteria in the blood while macrophages, once matured in tissues, combat intratissue disease agents. These cells exhibit unique abilities such as d

White blood cells (WBCs), or leukocytes, are vital elements of the blood responsible for protecting the body against invading organisms. They are classified into granulocytes (neutrophils, eosinophils, basophils) and agranulocytes (monocytes, lymphocytes), each playing specific roles in the immune s

Engagement of SARS-CoV-2 triggers the complement system and TLR 7 in neutrophils and macrophages, leading to the release of inflammatory cytokines and chemotactic factors. This results in the upregulation of adhesion molecules on blood capillary endothelial cells and leukocytes, facilitating leukocy
