What Challenges Are Associated with EQA in Histology?

Conducting EQA in histology presents several challenges:
- Sample Variability: Ensuring that all laboratories receive identical or highly similar samples can be difficult.
- Subjectivity in Interpretation: Histological interpretation can be subjective, making it challenging to standardize assessments.
- Resource Intensity: EQA programs can be resource-intensive, requiring significant time, effort, and financial investment.
- Maintenance of Standards: Continuously updating and maintaining high standards to reflect advancements in histological techniques can be demanding.
