IHC – TTF – 1

Description

TTF-1 (Thyroid Transcription Factor-1) immunohistochemistry (IHC) is a laboratory test used to detect the presence of the TTF-1 protein in tissue samples. It’s a valuable tool, particularly in diagnosing and classifying lung and thyroid cancers. In lung cancer, TTF-1 is a highly sensitive and specific marker for adenocarcinoma, helping to differentiate it from other subtypes like squamous cell carcinoma and metastatic adenocarcinomas. It also helps distinguish primary lung adenocarcinomas from metastatic adenocarcinomas
