What can cause low WBC low RBC low Neutrophils and high Eos?

Low white blood cells (WBC), red blood cells (RBC), and neutrophils, combined with high eosinophils, can indicate several conditions, including bone marrow disorders, autoimmune diseases, or certain infections. Possible causes include aplastic anemia, hypersensitivity reactions, or parasitic infections. Additionally, certain medications or chemotherapy can suppress bone marrow function, leading to these hematological changes. It's important to consult a healthcare professional for accurate diagnosis and appropriate management.
