What is a potential consequence of mislabeling a specimen?

• A. Increased lab efficiency
• B. Incorrect patient matching of results and potential harm.
• C. Improved accuracy
• D. No impact.

Answer: (B)

Mislabeling a specimen breaks the essential link between the patient and their sample. When a label is wrong or unclear, the lab results can be attached to the wrong patient, so clinicians may base decisions on someone else’s data. That can lead to wrong diagnoses, inappropriate treatments, or unnecessary procedures, and it often requires retesting and delays in care. All of this creates real risk of patient harm and undermines trust in the testing process.

Labeling errors do not improve efficiency or accuracy; they undermine them, and they certainly have a tangible impact on safety and care. Proper, accurate labeling is fundamental to ensuring the right patient receives the correct results and treatment.
