What is the most common reason for specimen rejection by the laboratory?

The most common reason for specimen rejection by the laboratory is improper labeling. Proper labeling is crucial because it ensures accurate identification and tracking of specimens from collection through testing. If a specimen is not labeled correctly, it can lead to significant issues, such as miscommunication regarding the patient’s identity, the type of test to be performed, and the clinical context of the sample. This mislabeling can compromise the integrity of test results, cause delays in diagnosis and treatment, and ultimately affect patient care.

Although other factors such as incorrect specimen type, insufficient volume, and delayed transportation are also important and can lead to rejection, improper labeling stands out as a prevalent issue across laboratories. This highlights the importance of strict adherence to labeling protocols in the specimen collection process to maintain sample integrity and ensure reliable laboratory results.
