A month later she returns for a blood pressure check and describes several days of a sore throat, fever, and chills. On examination she has a temperature of 39.5°C, a pharyngeal exudate, and submaxillary lymphadenopathy. A complete blood count (CBC) with differential is ordered STAT.CBC: Hematocrit/hemoglobin - 40%/13 g/dLWBC - 4.1 × 103/uLDifferential - Neutrophils 10% Monocytes 15% Lymphocytes 75%Platelet count - 150 × 103/uLSMEAR MORPHOLOGYNormocytic, normochromic red cells without aniso- or poikilocytosis. White cells are sparse, comprised mostly of normal-appearing lymphocytes, with a few normal-appearing neutrophils; no early neutrophil precursors (bands, myelocytes, or blasts) are seen. Platelets are normal.QuestionsGiven the CBC findings, what are the absolute numbers for each of the white cell lines and what abnormality is present?What further workup is needed—both history and laboratory testing?
