Why is it crucial to label blood specimens immediately after collection?

Labeling blood specimens immediately after collection is essential primarily to ensure accuracy in testing by associating the specimen with the correct patient. This practice helps prevent any potential mix-ups or errors that could arise if specimens are not properly identified in a timely manner. When a specimen is labeled right away, the patient's information—such as name, date of birth, and identification number—is securely tied to that particular blood sample, which is critical for accurate diagnosis, treatment, and follow-up.

Additionally, this immediate labeling reduces the risk of misidentification during processing, storage, and analysis, which can lead to incorrect results and subsequently impact patient care. Establishing a reliable link between the specimen and the patient is fundamental to maintaining patient safety and ensuring high standards of laboratory practice.
