Which error is primarily associated with human actions during laboratory testing, such as specimen handling and data entry?

• A. Latent Error
• B. Random Error
• C. Variation
• D. Active Error

Answer: (D)

Active errors are mistakes that occur at the moment of performing a task, directly caused by human action. In the lab, when a technician mislabels a specimen or enters the wrong data, the error happens during the testing workflow and can immediately compromise results. These errors are contrasted with latent errors, which are systemic weaknesses in processes, equipment design, or training that make mistakes more likely but aren’t the direct action themselves. Random error and variation refer to unpredictable fluctuations in measurement that aren’t tied to a specific human action. So, the scenario described—specimen handling and data entry—fits active errors because it involves the direct, human actions that can cause an error in testing.
