An 18-year old patient has a WBC count of 9 × 10⁹/L and 60% lymphs, 30% neutrophils, 6% monocytes, 3% eosinophils, and 1% basophils. The following that best describe this condition are: A) Relative and absolute neutrophilia B) Absolute neutropenia and absolute lymphocytosis C) Relative neutropenia and absolute lymphocytosis D) Relative lymphocytopenia and relative neutropenia

Question

The total WBC count is within the normal range, but the percentage of neutrophils is lower than normal (30% instead of 40-75%). This indicates relative neutropenia. However, the absolute neutrophil count cannot be determined without knowing the total WBC count. The percentage of lymphocytes is higher than normal (60% instead of 20-40%), indicating absolute lymphocytosis. The other values (monocytes, eosinophils, basophils) are within the normal range. Overall, the best choice is C, as it accurately reflects the relative and absolute changes in the WBC differential.
