What is a common error that can occur during specimen collection?

During specimen collection, improper technique leading to hemolysis is indeed a common error. Hemolysis refers to the breaking down of red blood cells, which can occur due to several factors during collection, such as using a needle that is too small, applying excessive suction while drawing blood, or shaking the sample vigorously after collection. This process can compromise the quality of the sample and thus affect the accuracy of test results.

Hemolysis can interfere with various laboratory tests, particularly those measuring analytes found in red blood cells, such as potassium or haptoglobin. This is significant in a clinical setting, as inaccurate results can lead to misdiagnosis or inappropriate treatment decisions for the patient.

In contrast, proper labeling of samples, immediate processing of samples, and correct storage of specimens are all practices that, when executed properly, minimize errors and ensure sample integrity. Each of these aspects is critical in maintaining the accuracy and reliability of laboratory results, but they are not classified as common errors in the way that hemolysis can occur as a direct result of poor technique during specimen collection.
