What is the effect of improper technique during blood collection?

Improper technique during blood collection can significantly affect the collection process and the quality of the specimen obtained. When blood is drawn incorrectly, several things can happen that could compromise the integrity of the sample. For instance, if a phlebotomist uses a needle that is too small for the vein, there may be hemolysis of the red blood cells, leading to erroneous lab results. Additionally, if the site is not cleansed properly, there could be contamination that can lead to misleading results for tests that require sterile samples.

Furthermore, incorrect positioning or handling of the collection tube can lead to the addition of air bubbles or improper mixing of additives, which can again affect the test outcomes. Ultimately, inaccurate test results can lead to wrong diagnoses, inappropriate treatment plans, and potentially serious consequences for patient care, emphasizing the importance of adhering to proper blood collection techniques. This is why the emphasis is on accuracy and following protocols during the phlebotomy process to ensure valid and reliable laboratory results.
