CD45 Count near me in Greater Noida

The CD45 Count test measures the presence and distribution of the CD45 protein on cells in tissue or biopsy samples. CD45 is expressed on nearly all mature leukocytes, including B and T lymphocytes, monocytes, and granulocytes.

By detecting CD45, the test helps doctors determine whether abnormal cells originate from the hematopoietic system (blood-derived) or another tissue type. Positive CD45 expression indicates leukocyte origin, which is critical for diagnosing leukemias, lymphomas, and other blood-related disorders. Absence of CD45 suggests that the abnormal cells are non-hematopoietic, aiding in the differentiation from other cancers. However, results must be interpreted as part of an immunohistochemical marker panel and correlated with morphology, clinical findings, and other investigations. This information supports diagnosis, classification, staging assessment, treatment planning, and monitoring in hematologic malignancies.
