Most analytic errors occur during which phases?

• A. During pre-analytic and post-analytic phases
• B. During the analytic phase
• C. During the post-analytic phase
• D. During collection

Answer: (A)

Most errors in the lab happen before and after the actual measurement, not during the testing itself. In the pre-analytic phase, issues like mislabeling, wrong patient identification, using the wrong tube, improper collection technique, delays in transport, or samples that are hemolyzed or degraded all occur before analysis and can render the result invalid or misleading. In the post-analytic phase, mistakes in reporting, data entry, result interpretation, and communication to the clinician can lead to incorrect clinical decisions even if the analysis was done correctly. The analytic phase—the measurement itself—tollows strict procedures, calibration, and quality controls, so it tends to have the lowest error rate. While collection is part of the pre-analytic process, focusing on both pre-analytic and post-analytic phases captures the broader sources of error that most influence test outcomes.
