The GATA-3 by IHC (Immunohistochemistry) test is a specialized diagnostic procedure used to detect the presence of the GATA-3 protein in tissue samples. GATA-3 is a transcription factor commonly expressed in breast and urothelial carcinomas, and its detection helps pathologists confirm tumor origin and differentiate between cancer types. This test is performed to support accurate cancer diagnosis, guide treatment planning, and improve patient outcomes by providing precise information about tumor classification.
IHC detects protein expression in tissue, while genetic testing analyzes DNA mutations.
Positive results are strongly associated with breast carcinoma and urothelial carcinoma.
No, it is a natural protein marker. The test only detects its presence in tumors.
Without testing, cancer origin may remain unclear, delaying accurate diagnosis and treatment planning.
It usually does not need repetition unless new tissue samples are collected for further evaluation.
Yes, it is safe and can be used in pediatric cases where cancer diagnosis is required.
