Hereditary spherocytosis (HS) is a type of congenital hemolytic anemia, in which heterogeneous alterations in one of the six genes that encode for proteins involved in vertical associations which tie the red blood cell (RBC) membrane skeleton to the lipid bilayer causesdysfunction or deficiency of cell membrane protein resulting in spherical-shaped, hyper- dense, and poorly deformable RBCs with a shortened life span. We report a case of HS in a 2-month-old female who presented with severe anemia, jaundice, and hepatosplenomegaly.The peripheral blood smear showed spherocytosis and reticulocytosis. The osmotic fragility was positive and direct antiglobin test was negative. The osmotic fragility test and direct antiglobulin test were positive. She was managed with packed RBCs (PRBCs) transfusionand folic acid supplementation.

Spurious thrombocytopenia or pseudothrombocytopenia (PTCP) is an important clinical entity, in which the presence of autoantibodies or anticoagulants used during blood sampling causes in vitro clumping of platelet and thereby resulting in a falsely low automated platelet count. The most common cause of platelet clumping is ethylenediaminetetraacetic acid used as an anticoagulant in the blood samples. The other reasons for PTCP include the presence of autoantibodies such as cold agglutinin, giant platelet, and platelet satellitism. There are very few cases of spurious thrombocytopenia in the newborn period published in the literature. We are reporting a case of PTCP due to platelet satellitism in a baby born to a mother with a similar condition.
