Immunology Laboratory

The Immunology Laboratory at The Children’s Hospital of Philadelphia offers an extensive menu of assays to examine both the cellular and humoral immune systems. The lab uses flow cytometry for immunophenotyping studies to characterize leukemias and lymphomas; to enumerate T, B, and natural killer cells along with their subsets; to measure oxidative metabolism of phagocytes used for the diagnosis of chronic granulomatous disease (CGD); and to aid in the diagnosis of hereditary spherocytosis (HS).

Immune function can be assessed by mitogen or antigen stimulated lymphocyte cultures and the measurement of chemotaxis (motility). A broad selection of assays are also available to monitor the normal humoral immune system as well as markers for a number of autoimmune disorders.

The lab offers numerous comprehensive high-quality laboratory tests in the areas of immunology, oncology, hematology, rheumatology and gastroenterology. Our laboratory has a specific focus and expertise in pediatric immunodeficiencies as well as leukemia and lymphoma, where we offer specialized testing and interpretation.

We offer a broad selection of standard as well as unique clinical assays performed by highly-trained technologists in these areas using the newest technology. Our goal is to work closely with our clinical and research colleagues to provide cutting-edge laboratory tests to expedite and aid in diagnostic patient care.
