NUT Immunostain, Technical Component Only
Use
This test aids in the diagnosis of nuclear protein in testis midline carcinoma. It specifically detects the presence of chromosomal rearrangements involving the NUT gene on chromosome 15q14, associated with NUT midline carcinoma (NMC). NMCs are aggressive and highly lethal carcinomas that are difficult to distinguish from other poorly differentiated carcinomas using only morphological analysis.
Special Instructions
Not provided.
Limitations
The test does not include pathologist interpretation, which is necessary for a complete diagnostic evaluation. The age of the paraffin section can affect immunoreactivity, and environmental factors can impact the charge of glass slides, potentially affecting staining outcomes. Best practices for slide storage should be followed to mitigate these issues.
