Overview
The purpose of the Immunophenotyping by Flow Cytometry CD3 Test is to evaluate T-cell immunity by quantifying CD3+ T-lymphocytes in blood or bone marrow samples. This test helps diagnose T-cell related cancers, such as T-cell acute lymphoblastic leukemia and peripheral T-cell lymphomas, as well as immune disorders including autoimmune diseases and HIV/AIDS. It provides crucial information for treatment planning, monitoring disease progression, and assessing immune status in transplant patients.
