Missing Blood Sample Protocol: Steps to Locate and Document a Lost Specimen

If a blood sample sent for collection cannot be located in the refrigerator, follow these steps immediately:

1. Contact the Sender: Notify the person or facility that shipped the sample. They can initiate tracking or arrange a replacement draw.
2. Verify Labeling: Check the packaging for intact, legible labels. A damaged or missing label can cause misplacement.
3. Search Thoroughly: Look behind, under, and between other items in the refrigerator. Check adjacent units or designated "stat" areas.
4. Alert the Receiving Laboratory: Inform the lab that the specimen has not arrived. Ask for their specific protocol for missing samples—they may require a formal incident report.
5. Document Everything: Record all actions: times of calls, names of contacts, search locations, and lab instructions. This documentation is critical for quality assurance and potential investigations.

Prompt, systematic action minimizes diagnostic delays and protects patient care.
