How it works
- Place an order through the Junction Dashboard or the Create Order endpoint.
- Junction validates the order and creates a requisition with the selected partner laboratory.
- After the order reaches
requisition_created, the patient can receive instructions for booking the draw. - Book or request an appointment with a phlebotomy provider. See Service Tiers for the available scheduling workflows.
- The phlebotomist visits the patient, collects the sample, and delivers it to the laboratory.
- Junction makes results available as structured data and a PDF. See Result Formats.
Some Teams can schedule an appointment before the requisition is created. See Scheduling Appointments Before a Requisition Has Been Created.
What to plan for
- Coverage: Appointment availability depends on the patient’s address and the phlebotomy providers serving that area. Use the Area Info endpoint before presenting mobile phlebotomy as an option.
- Patient age: Phlebotomy appointments are not supported for patients under 18 years old.
- Address: Availability requests require a reachable street address, including a street number and unit where applicable.
- Active appointments: A patient cannot have more than one active appointment with the same phlebotomy provider.
Instructions for the phlebotomist
