Diagnosing leukocytosis involves several steps. Initially, a complete blood count (CBC) test is performed to measure WBC levels. If elevated levels are detected, further tests may be conducted to determine the underlying cause. These tests may include:
Bone marrow biopsy: To check for abnormalities in blood cell production. Imaging studies: Such as CT scans or MRIs to identify tumors or other abnormalities. Flow cytometry: To analyze cell types and identify specific subtypes of white blood cells.
