What is a potential consequence of using the improper tube for the testing being ordered?

Using the improper tube for specimen collection can lead to inaccurate test results, which can significantly impact patient care and diagnosis. Each collection tube contains specific additives that are designed to preserve the specimen for the type of test being performed. For instance, certain tubes contain anticoagulants to prevent clotting when performing tests that require plasma, while others may contain gel separators for serum tests.

If a tube with the wrong additive is used, it can alter the composition of the specimen. For example, using a tube with an anticoagulant for a test that requires a clotted specimen can lead to erroneous results due to the presence of proteins or cell components that are not expected in that test matrix. This could mislead healthcare providers regarding a patient's condition, potentially resulting in incorrect treatments or diagnoses.

On the contrary, while some other options mention different aspects of specimen collection, they do not accurately address the critical impact that using the correct tube has on the accuracy of test results, which is central to patient safety and effective healthcare delivery.
