Final answer:
The "standard of care" for Phlebotomy is set by the American Society of Phlebotomy Technicians, with additional influence from other professional organizations like the CLSI and NPA.
Step-by-step explanation:
The group primarily responsible for setting the "standard of care" for Phlebotomy is the American Society of Phlebotomy Technicians (ASPT). They certify individuals who have passed a national examination, indicating a recognized standard of knowledge and skill in the field. Alongside ASPT, other professional organizations may also influence phlebotomy standards, including but not limited to the Clinical and Laboratory Standards Institute (CLSI) and the National Phlebotomy Association (NPA). These organizations provide guidelines and accreditations that labs and hospitals adhere to when hiring skilled professionals in phlebotomy.
