CD1A (Pan T Cell Marker) in Mahalaxmi West, Mumbai

The cluster of differentiation (CD) refers to proteins that are expressed on the surface of the cells of the immune system. For ease of identification, each surface molecule has a different number that plays a unique role in the immune system. The CD1A protein is the first member of the CD1 system. It plays the role of a marker for dendritic cells and is mainly known as a protein-coding gene. Evaluation of CD1A T cells helps detect a wide variety of diseases. For this purpose, a CD1A Pan T-cell marker test proves helpful.

The analysis of the CD1A expression helps detect the following:

• Langerhans cells
• Immature T cells

The CD1A function can also prove helpful in marking cortical thymocytes. Following are some diseases associated with specific markers like CD1A:

• Histiocytosis
• Langerhans cells histiocytosis

In these conditions, histiocytes, a group of white blood cells (WBCs), accumulate in one or more of the following parts or organs:

• Spleen
• Liver
• Lymph nodes
• Skin
• Bones

This condition can cause damage to the tissues and lead to benign or malignant tumours. On the other hand, Langerhans cells histiocytosis is a disease that can lead to lesions in multiple places of the body. This illness is primarily a case of genetic mutation. Hence, your doctor can recommend the CD1A Pan T-cell marker test to detect such rare diseases.

The medical testing of CD1A protein is done either through the analysis of blood or tissue sample. In most cases, a blood sample can be sufficient to study the CD1A expression and levels. During the test, a lab technician can use the process of venepuncture. The professional can draw blood from a vein on your arm during this process. Hence, you might face mild pain or irritation at the site of needle entry.

Before testing CD1A T cells, the medical lab may require your clinical history. This data is necessary for determining the influence of various factors on CD1A expression and the behaviour of specific markers.

You do not need to fast before providing the blood or tissue sample. The family members of CD1 can differ in their cellular localisation. Hence, the testing requires in-depth analysis.

At Apollo 24|7, you can get the CD1A Pan T-cell marker test done at reasonable rates. We ensure a detailed analysis of your results primarily within three days.
