How should blood samples be handled after collection?

After blood samples are collected, they should be sent to the lab immediately for analysis. This prompt transportation is crucial because it preserves the integrity of the samples and minimizes the potential for changes in the blood's components that can occur due to environmental factors such as temperature fluctuations or exposure to light. Immediate processing helps ensure that the test results reflect the patient's current condition accurately, which is vital for diagnosis and treatment.

Other handling methods, like allowing samples to sit at room temperature for several hours or storing them in a refrigerator for an extended period, can lead to alterations in the chemical composition of the blood, degradation of cellular components, or the growth of bacteria, all of which can compromise test results. While packaging samples in ice might be necessary for specific tests that require temperature control, such as certain hormone levels, it typically does not replace the need for immediate transport to the laboratory. Thus, the best practice is to expedite the delivery of blood samples to facilitate timely and accurate laboratory assessment.
