urine sample(>= 30 mL) to screen for internal contamination with Ra-226. This mismatch created an unnecessary burden for the patient and introduced unnecessary complexity to sample storage and handling for the public health laboratory. However, when a 24-hour collection is already obtained, laboratories can reduce handling complexity by aliquoting into an appropriate container before shipment.

Identifying procedural gaps, like the specimen collection and handling methods, provided meaningful opportunities for system improvement. Moving forward, regular exercises and drills will create operational muscle memory to reduce hesitation and confusion in response events. The exercises will reinforce the notification pathways to reduce communications confusion. Early coordination between clinicians, laboratories and federal partners on sampling requirements before specimen collection can be highlighted during drills to minimize procedural issues. By strengthening clarity about roles, refining specimenhandling protocols and formalizing communication pathways, North Dakota expands an already strong foundation.

The 2025 radiation incident demonstrates that preparedness is not a static achievement but an ongoing process. It benefits from practice, partnership and continual reassessment. The event serves as a powerful reminder that preparedness and drills are not merely exercises— they are essential components of real-world readiness. g

critical quality assurance risk( the " validation gap ").

• Capacity and Logistics. Procurement systems rely on rigid annual cycles, frequently resulting in stockouts during high-volume testing. This is compounded by the widespread presence of the " one-person lab " model in Upazilas, where a single medical technologist manages the entire complex diagnostic workflow. Sample tracking is informal or non-existent outside vertical disease programs, hindering outbreak investigations and reliable chain-of-custody. For sample transport procedures, 79 % of national departments have completely standardized protocols, but three laboratories rely on transport arrangements on an“ as needed” basis, and others report non-applicability due to their non-infectious specimen focus( e. g., food samples).

• Communication. Post-analytical communication for clinical results remains largely informal( e. g., phone calls), undermining the formal dissemination pathways necessary for integrated public health action.

Strategic Imperatives

The data collected provides DGHS with insights into capacity and communication between the different laboratory tiers. To build a cohesive and resilient network, targeted investments must prioritize: digital integration via a national LIS, creating dedicated full-time quality manager roles and implementing real-time resource planning to ensure sustainable operations at all tiers.

By addressing these, Bangladesh can successfully move toward establishing a truly integrated and responsive national public health laboratory network. g
