Thyroglobulin by Immunohistochemistry
Also known as: THYRO IHC
Use
Thyroglobulin by Immunohistochemistry is used as a stain in histological examinations. This test is crucial for the identification and assessment of thyroid tissue, particularly in cases of thyroid cancer. It assists in detecting thyroglobulin expression in tissues, aiding in the differentiation of thyroid pathology from other types of tissue and confirming a diagnosis of thyroid cancer. This test is intended for use in clinical settings requiring detailed tissue morphology analysis.
Special Instructions
Submit electronic request for Immunohistochemistry. If unable to order electronically, use an ARUP Immunohistochemistry Stain Form with an ARUP client number. Use the ARUP tissue transport kit for specimen transportation. Contact ARUP Client Services for additional technical details or to acquire supplies.
Limitations
This test is performed as a technical stain and return service, indicating it is not suitable for direct clinical diagnostics without supporting histological interpretation. Specimens with non-representative tissue type or depleted specimens are unacceptable for testing. The stability of specimens is indefinite when stored ambiently or refrigerated, but freezing is not acceptable, potentially affecting sample integrity.
