What is a misstep when collecting blood that can compromise results?

Using an incorrect tube or improper order of draw is a critical misstep in blood collection that can significantly compromise test results. Each type of blood test requires specific additives that may be present in different tubes; thus, using the wrong tube can lead to contamination and inaccurate results. Additionally, the order of draw is important to avoid cross-contamination between different additives found in the tubes. If, for example, an additive from one tube contaminates another, it could interfere with the assays being performed on that sample, leading to false results and impacting patient care.

In contrast, using a sterile needle is essential for preventing infections, while collecting blood during fasting is typically a protocol for certain tests and would not necessarily compromise the integrity of the blood sample. Not using gloves, though a best practice for safety, is more about protecting the healthcare provider rather than affecting the blood samples directly. Proper techniques and protocols in blood collection are essential for ensuring that laboratory results are accurate and reliable.
