What is this test?

CD1a is a membrane surface glycoprotein that has good specificity for Langerhans cells and immature T cells. In normal skin, CD1a stains scattered Langerhans cells in the upper dermis and epidermis; reactivity in normal thymus gland is in the cortical thymocytes (immature T cells). This immunostain is useful in phenotyping acute lymphoblastic leukemia/lymphoma of T-cell lineage and in diagnosis of Langerhans cell histiocytosis. Powerful antigen presenting cells present in skin and epithelia, from interdigitating cells. Immunohistochemical studies for CD1a antigen have reported a reduction in epidermal Langerhans cells in graft versus host disease and the participation of CD1a antigen-positive dendritic cells in atherosclerotic lesion formation and asthmatic inflammation.
