Pancytopenia is a reduction in the number of RBCs, WBCs, and platelets in the peripheral blood below the lower limits of the age-adjusted normal range for healthy people. It is therefore the combination of anaemia, leukopenia, and thrombocytopenia. It may result from decreased production of blood cells or bone marrow failure, or from their immune-mediated destruction or non-immune-mediated sequestration in the periphery. The diagnosis is made from the results of an automated FBC.
