CD1a (Pan T Cell Marker)

CD1a (Pan T Cell Marker)
Measures CD1a protein on tissue cells to identify Langerhans cells and help diagnose related conditions.
What is a CD1a (Pan T Cell Marker) Test ?
This test checks for the CD1a protein on cells in a tissue sample. CD1a is found on certain immune cells, including Langerhans cells in the skin and some thymic cells. It helps the immune system recognize lipid antigens. Doctors use CD1a staining to identify specific cell types in biopsies. It is important for diagnosing conditions such as Langerhans cell histiocytosis and some rare tumors. Pathologists often use CD1a together with other stains to confirm a diagnosis. The result helps guide treatment decisions and further testing. The test is done on biopsy tissue and interpreted by a specialist.

Why Take a CD1a (Pan T Cell Marker) Test ?
CD1a (Pan T Cell Marker) is used in immunohistochemistry panels for skin, bone, or lymph node biopsies when abnormal lesions appear. Doctors may order it if a patient has persistent skin rashes, raised lumps, bone pain, or swollen lymph nodes. It helps diagnose Langerhans cell histiocytosis and certain immune cell tumors. Abnormal results usually reflect disease processes rather than lifestyle, and a family history of histiocytic disorders may prompt earlier testing.
