Why is it essential to follow the manufacturer's guidelines for blood collection tubes?

Following the manufacturer's guidelines for blood collection tubes is crucial primarily because it ensures the compatibility of anticoagulants and additives with specific tests. Each type of blood collection tube contains specific additives, such as anticoagulants or gels, which are designed for particular types of analyses. These additives can significantly influence the quality of the sample and the accuracy of the test results.

Using the wrong tube or not adhering to the recommended collection practices can lead to improper sample preservation, hemolysis, or contamination, ultimately affecting the results. For example, if a serum test is performed using an anticoagulant tube, it could lead to erroneous measurements because the presence of anticoagulants can interfere with the testing process.

While patient comfort, time efficiency, and the number of tests performed are important considerations in clinical practice, the primary focus when collecting blood samples should always be on obtaining accurate and reliable results, which directly hinges on the correct use of collection tubes and adherence to the manufacturer's instructions.
