Final answer:
Effective communication and interpersonal skills are crucial for phlebotomists in liaising with the lab and patients, interacting with patient's families, and collaborating with other healthcare professionals.
Step-by-step explanation:
Use of effective communication and interpersonal skills is necessary for phlebotomists when they act as the liaison between the laboratory and patients, interact with patients' families and visitors, and work collaboratively with other health-care professionals. Communication is integral in these roles as phlebotomists are required to educate patients about the blood draw process, address any concerns, and ensure accurate information exchange with other healthcare team members. Performing tasks such as venipuncture, managing patient information, and working with blood bank technology further illustrate the need for such skills due to the precision and care required in these procedures.
