CD19 Count near me in New Delhi
The CD19 Count test measures the number of CD19+ B cells in blood. CD19+ B cells are a type of white blood cell that plays an important role in the immune system. This test is commonly used to evaluate immune system health and support the diagnosis of certain blood cancers or immune disorders. It is available at an affordable price with Tata 1mg labs in New Delhi.
The CD19 Count test uses a highly sensitive technique called flow cytometry to detect and count CD19+ B cells in a blood sample. This test is usually recommended when doctors suspect an immune disorder or a condition affecting B cells, like leukemia or lymphoma. It may be advised if there are symptoms such as unexplained weight loss, pale skin, unusual bleeding, fever, night sweats, or swelling in the lymph nodes or organs. It also plays an important role in assessing how well a patient's immune system is recovering after bone marrow or organ transplantation, or in response to immunosuppressive therapy. Additionally, it also plays a vital role in monitoring disease recurrence, determining the extent of cancer involvement, and evaluating the effectiveness of treatment.
No special preparation is required for the CD19 Count test. However, provide a brief clinical history at the time of sample collection.
