What does "specimen rejection" refer to in laboratory protocols?

Specimen rejection refers to the process of not accepting a sample due to issues that could impact the validity or reliability of test results. This could arise from various factors such as poor labeling, inappropriate collection methods, contamination, or the specimen being damaged or expired. When a specimen is rejected, it ensures that only high-quality, reliable samples are processed, ultimately leading to accurate diagnoses and effective patient care.

The focus on rejecting specimens when they do not meet laboratory standards is critical in maintaining the integrity of laboratory testing and ensuring that patient safety is prioritized. Each laboratory may have specific criteria and guidelines for when a specimen should be rejected, making it essential for laboratory personnel to be well-trained on these protocols.
