If a unit of platelets has visible clots but otherwise appears normal, what should the technologist do?

When a unit of platelets shows visible clots but otherwise appears normal, it is critical for the technologist to quarantine the unit for Gram stain and culture. This is because the presence of visible clots may indicate possible contamination or microbial growth within the platelet unit, which could pose a risk to patients if transfused.

Quarantining the unit allows for an assessment to determine whether any pathogenic organisms are present, as this could lead to complications or transfusion reactions in recipients. Culturing the unit fosters the identification of bacteria or other pathogens, which are particularly concerning in platelet products that are stored at room temperature, as they provide an ideal environment for bacterial growth.

Other actions, such as issuing the unit without concern, filtering, or centrifuging, do not adequately address the potential infectious risks associated with the visible clots. Proper quality control and safety measures must be undertaken to protect patient health. Hence, the correct protocol in this scenario prioritizes safety through careful investigation of potential contamination.
