- multiple myeloma
- acute lymphoblastic leukemia
An increased B cell count may suggest: - chronic lymphocytic leukemia
- multiple myeloma
- Waldenstrom's macroglobulinemia
- DiGeorge syndrome
A decreased T cell count may suggest: congenital T-cell deficiency disease Nezelof syndrome DiGeorge syndrome Wiskott-Aldrich syndrome B cell proliferative disorders acquired immunodeficiency syndrome chronic lymphocytic leukemia Waldenstrom's macroglobulinemia A decreased B cell count may suggest: - acute lymphoblastic leukemia
