Quizplus · Accepted Answer

The range of confidence limits in the clinical laboratory is generally set at ±2 to ±3 standard deviations (SD) from the mean. While ±1 SD provides a narrow range, it may not be acceptable in certain clinical situations where a wider range of acceptable variability is required. ±4 SD is too wide and may include outliers that could affect patient care. Therefore, the best choice for the highest acceptable range for confidence limits in the clinical laboratory is C) ±3 SD.
