What does this test CD21 Test Immunohistochemistry identify?

CD21 Test Immunohistochemistry

The CD21 Test Immunohistochemistry is a diagnostic test that identifies the presence of CD21 antigens in tissue samples. CD21, also known as complement receptor 2 (CR2), is a protein found on the surface of B cells and follicular dendritic cells.

By conducting immunohistochemistry staining, the test can detect the expression of CD21 in tissues, which can help in the diagnosis of certain diseases and conditions. CD21 is involved in the immune response and plays a role in the activation and regulation of B cells.

The CD21 Test Immunohistochemistry is commonly used in the diagnosis of lymphomas, B cell neoplasms, and other lymphoid disorders. It can also be helpful in identifying the presence of infectious agents in tissues, as CD21 acts as a receptor for certain viruses.
