What should be done with any tube that has been used but was unsuccessful in obtaining blood?

When a tube has been used but was unsuccessful in obtaining blood, it is important to dispose of it properly to maintain safety and prevent any risk of contamination. Used blood collection tubes can retain residual blood, which poses a risk for potential infection if not handled appropriately.

Disposing of the tube in a sharps container is the correct practice because these containers are specifically designed to safely contain items that can puncture or cut, minimizing the risk of exposure to bloodborne pathogens. This disposal method ensures that any hazardous waste is managed properly, following protocols that maintain a safe healthcare environment.

Other options do not align with safety protocols. Re-using the tube can lead to inaccuracies and further complications in blood collection and testing. Storing the tube for future reference is unnecessary and impractical, as there is no valid use for a tube that has not successfully collected a sample. Returning it to the lab for inspection does not serve a purpose, as the tube's failure does not warrant further analysis in that context.
