Fever and anemia

Patient: 12 days back my mother aged 58 had severe shivering with high-grade fever. Blood test was done with malaria and typhoid negative. Anticipating viral infection she was run on antibiotics for 5 days. At that time the report of blood showed some alarming signs. Hb-8.8, Neutrophil-90, Lymphocyte-9, ESR-40. After two days of finishing the course, she had fever again but this somewhat low grade. Again the blood test was done and showed the following results. Hb-7.1, Lymphocyte-15, neutrophil-83, Esr-50. Again she has been put on antibiotics.
