There can be training programs which focuses on proper tube filling techniques, visual inspection for underfilled tubes, and the importance of sample volume standardization can be implemented for healthcare professionals and laboratory staff. A Regular refresher courses and proficiency testing can reinforce these concepts and be a great help for everyone. Also, using correct tube filling techniques can avoid having inaccurate results.

According to National Library of Medicine (2020, June 15), that to ensure the right sample collection it is necessary to standardize this procedure and organize trainings and audits for all involved members of the healthcare staff regularly. Also, that by the help of World Health Organization (WHO), in the national language and establish a system to guarantee that all phlebotomists are trained correctly.

Underfilling of blood collection tubes occurs during the pre-analytical phase. However, this phase of testing is considered the most vulnerable part of the total testing process and poses the greatest challenges to laboratory professionals (Simundic & Lippi, 2012). It is also regarded as less standardized and a significant contributor to laboratory errors (Neuwinger et al., 2019). Therefore, continuous education, certification, and training of healthcare practitioners in blood drawing responsibilities, along with improved standardization of phlebotomy techniques and dissemination of operative guidelines, would enhance the chance of obtaining specimens of consistent quality (Lippi et al., 2006).
