Priorities in histology are determined based on several factors: - Clinical Urgency: Samples from critical patients or those suspected of serious conditions are given top priority. - Research Needs: Samples required for ongoing research projects may be prioritized based on deadlines and project importance. - Sample Type: Some sample types, like frozen sections, require immediate processing and are thus prioritized over routine samples. - Volume: High-volume periods may require adjustments in priority to handle the increased workload efficiently.
