Immunoglobulin D (IgD) by Immunohistochemistry
Also known as: IGD IHC
Use
The Immunoglobulin D (IgD) by Immunohistochemistry test is used as a technical service to detect the presence of IgD in tissue or cell specimens. The test is typically used by pathologists to determine the expression of IgD, which can have diagnostic implications in various clinical contexts, such as distinguishing between different types of lymphoid neoplasms. The immunohistochemical staining method allows for the visualization of IgD in tissue samples, making it a useful tool in diagnostic histopathology.
Special Instructions
This test requires submission of a tissue block or unstained slides, which must be formalin-fixed and paraffin-embedded. If slides are sent, they must be 3- to 5-micron thick sections and positively charged. Specimens should be protected from excessive heat and shipped at room temperature or refrigerated during warmer months. Electronic requests are preferred; if unavailable, use the ARUP Immunohistochemistry Stain Form with an ARUP client number.
Limitations
This test has not been cleared or approved by the US Food and Drug Administration and is performed as a stain and return service only. It is not suitable for use with specimens submitted with non-representative tissue types or depleted specimens. The performance characteristics of this test were determined by ARUP Laboratories in a CLIA certified laboratory.
