Overview
The primary purpose of the Immunohistochemistry CD163 Test is to evaluate CD163 protein expression on macrophages in tissue samples, which helps in identifying tumor-associated macrophages (TAMs) and assessing inflammation. This information is critical for diagnosing cancers like lymphoma and leukemia, monitoring inflammatory conditions such as rheumatoid arthritis and sarcoidosis, and determining disease prognosis. The test aids healthcare providers in making informed treatment decisions and tracking therapeutic effectiveness.

- Insufficient sample size
- Missing required documentation
Understanding Your Results
High CD163 expression
May indicate poor prognosis in cancers like lymphoma or active inflammation in conditions such as rheumatoid arthritis.
Low or no CD163 expression
Suggests lower macrophage activity; correlation with clinical context is recommended.
Consult your oncologist or specialist if you experience persistent symptoms like fever, fatigue, weight loss, or if results indicate abnormal CD163 expression.
Limitations
- ⚠Not a standalone diagnostic; must be correlated with clinical findings and other tests.
- ⚠Results may vary based on tissue quality and laboratory techniques.
- ⚠Limited to assessing macrophage markers and not specific cancer types.
Risks & Considerations
- ●Minimal risks from biopsy procedure, such as bleeding or infection.
- ●False positives or negatives due to technical issues.
Interfering Factors
- ●Poor tissue preservation
- ●Incorrect sample handling
- ●Inadequate clinical history
