Why is it important to check the expiration date on collection tubes?

Checking the expiration date on collection tubes is crucial because expired tubes can compromise the integrity of the test results. Collection tubes are manufactured with specific additives, such as anticoagulants or preservatives, which are essential for maintaining the sample's stability and ensuring accurate analysis. Over time, these additives may degrade or lose their effectiveness, leading to erroneous laboratory results, which can ultimately affect patient diagnosis and treatment. By ensuring that only tubes within their expiration dates are used, healthcare professionals can maintain the reliability and validity of the testing process.
