Which of the following are examination errors that lead to diagnostic errors?

• A. Failure to sample enough information
• B. Errors in detecting variance
• C. Both A and B
• D. None of the above

Answer: (C)

A solid examination hinges on gathering enough information and recognizing how findings vary. If you don’t sample enough information, you’ll miss important signs, symptoms, or contextual factors that shape the diagnosis, leaving a gaps-filled picture that can lead to an incorrect or delayed diagnosis. Likewise, not detecting variance means you miss how findings change across tasks, time, or conditions, which can hide instability, pain fluctuations, or measurement noise that clarifies what’s really happening. When either of these occurs, the risk of diagnostic error rises, and recognizing both aspects helps prevent misdiagnosis.
