What percentage of errors affecting test results are attributed to preanalytical errors?

Preanalytical errors significantly impact laboratory test results, and research indicates that a considerable portion of these errors occurs before the actual analysis of specimens. Approximately 56% of errors affecting test results are attributed to preanalytical factors, which include issues like improper specimen collection, inadequate labeling, delays in processing, and transportation challenges.

Understanding the importance of preanalytical error management is crucial in phlebotomy and laboratory practices as these errors can lead to misdiagnoses and inappropriate treatment plans. Focusing on reducing these errors through proper training, standardized procedures, and protocols helps ensure the reliability of test outcomes and ultimately improves patient care.

The other percentages represent levels of errors not specifically tied to the preanalytical phase, reflecting a commitment to addressing errors that occur in analytical and post-analytical processes, but they do not capture the significant impact of preanalytical factors as comprehensively as the 56% statistic does.
