NHA Phlebotomy Certification Practice Exam

What type of variables are errors in prioritizing specimens appropriately classified as?

1. Post-examination variables

2. Pre-examination variables

3. Examination variables

4. Different types of variables depending on the type of laboratory

The correct answer is: Pre-examination variables

Errors in prioritizing specimens are classified as pre-examination variables because they occur before the actual testing phase. Pre-examination variables encompass all factors that can influence the quality or integrity of the specimen before it reaches the laboratory for analysis. This includes aspects such as patient preparation, specimen collection techniques, and the handling and transportation of the specimens. When prioritization of specimens is not done correctly, it can lead to delays in processing the most critical samples, potentially affecting patient outcomes. Therefore, these errors are considered pre-examination issues since they take place prior to the examination of the samples in the laboratory. Understanding this classification is crucial for phlebotomists and laboratory personnel to ensure that patient care is optimized through proper sample management and prioritization.
