Junction offers multiple Tiers of phlebotomy services, with different coverage capabilities:
  • Appointment Ready: An appointment is booked in Junction using the patient’s address and the appointment’s date and time. The scheduling is completely synchronous and fully controlled by Junction’s customers through our API.
  • Appointment Request: An appointment is requested through the Junction system using the patient’s address. A phlebotomist will eventually assign themselves to the appointment and define the appointment’s date and time with the patient.
