Clot in the Blood Bag: A Case Report

Clot formation within a blood bag is a rare but significant issue, posing risks to the safety and quality of transfused blood products. We report the root cause analysis of a large clot found in a blood bag during routine component preparation. The analysis identified three potential contributing factors: improper vein selection leading to low flow rates, delays in tube stripping, and the use of a faulty blood collection monitor. These factors together facilitated the activation of coagulation, resulting in clot formation. To address these issues, corrective actions were implemented, including enhanced staff training on vein selection and phlebotomy techniques, timely and proper tube stripping procedures, and the replacement of faulty blood collection monitors with regularly calibrated equipment. Additionally, standard operating procedures (SOPs) were updated to incorporate these corrective measures. The implementation of these actions aims to prevent the recurrence of such incidents, ensuring the integrity of blood products and the safety of transfusion practices. This case highlights the importance of continuous monitoring and adherence to established protocols in blood collection and processing.
