What does a properly collected blood sample ensure?

A properly collected blood sample is crucial for several reasons, all of which contribute to the integrity of laboratory testing.

Firstly, minimal contamination is important because any foreign substances introduced during the collection can interfere with the test results, leading to inaccurate conclusions regarding a patient's condition. Ensuring that the sample collection process is sterile reduces the risk of contamination, thereby preserving the sample's quality.

Secondly, the correct anticoagulant levels are vital when collecting blood for specific tests, especially when dealing with plasma or whole blood samples. If the sample does not contain the appropriate anticoagulant or the levels are wrong, it can lead to clotting or inadequate preservation of the sample. This aspect is especially important in tests that require blood to remain in a liquid state for analysis.

Lastly, accurate test results are predicated on both minimal contamination and proper use of anticoagulants. If the sample collection is not done properly, it can result in misleading results, which could lead to inappropriate patient care or misdiagnosis.

The overarching theme is that all these factors—minimal contamination, correct anticoagulant levels, and accurate test results—are interconnected and essential to obtaining reliable laboratory findings. Therefore, the most comprehensive answer recognizes that all these components are satisfied with a properly collected blood
