AMCA Phlebotomy Practice Exam – Complete Prep Guide

Properly disinfecting blood collection sites is crucial primarily to prevent infection and contamination of the sample. Blood collection procedures involve breaking the skin barrier, which can introduce microorganisms from the skin surface into the vascular system if not adequately disinfected. Ensuring that the site is free from pathogens minimizes the risk of healthcare-associated infections for the patient, which is essential for their safety and wellbeing.

Furthermore, disinfection helps in maintaining the integrity of the blood sample. Contaminants can alter test results, leading to inaccurate diagnoses or treatment plans. Therefore, the thorough disinfection of the blood collection site is a critical step in phlebotomy that protects both the patient and the accuracy of laboratory testing.

While conforming to regulatory standards and reducing patient anxiety are important factors in the overall practice of phlebotomy, the primary focus should always be on infection control and ensuring the validity of the sample being collected.
