Hepatocyte Immunostain, Technical Component Only
Use
This test is useful for distinguishing hepatocellular carcinoma from other types of cancer. Normal liver tissue is expected to show a positive result with distinct granular cytoplasmic staining of hepatocytes. Bile ducts and nonparenchymal liver cells are expected to show a negative result.
Special Instructions

Limitations
The effectiveness of this test can be impacted by the age of the paraffin section, as the immunoreactivity can degrade. Environmental factors affecting the charge of glass slides may alter slide staining. Best practice suggests that paraffin sections be cut within 6 weeks of analysis. Unsuitable glass slide surfaces may also contribute to staining inconsistencies.
