What is a common reason for rejecting a blood specimen?

A common reason for rejecting a blood specimen is that it was collected in a non-sterile container. Using a non-sterile container can lead to contamination of the specimen, which may compromise the validity of the test results. Contaminants, such as bacteria and other foreign substances, can interfere with laboratory analyses and lead to inaccurate diagnostic information. For accurate testing, it is essential to collect blood specimens in containers that have been properly sterilized and are appropriate for the specific tests being conducted. This ensures the integrity of the specimen and the reliability of the results.

Correct labeling, timely collection, and adherence to fasting protocols are crucial components of proper specimen collection but do not inherently warrant rejection of the specimen. In fact, they are indicative of good practice in specimen collection and handling.
