Question: 1 / 400

What is the significance of the "expiration date" on blood collection tubes?

It indicates the period during which the tube is effective and safe to use

The "expiration date" on blood collection tubes is crucial because it indicates the period during which the tube is effective and safe to use. Blood collection tubes contain specific additives, such as anticoagulants or preservatives, which are designed to maintain the integrity of the blood sample during storage. Over time, the effectiveness of these additives can diminish. If a tube is used past its expiration date, there is a risk that the sample may not be preserved correctly, potentially leading to inaccurate test results.

Using tubes beyond their expiration dates can compromise sample quality, which is critical in ensuring accurate diagnosis and treatment. Therefore, adhering to expiration dates is a fundamental practice in phlebotomy to uphold the quality and reliability of laboratory testing.
