Order Lifecycle

As discussed in Lab Test Lifecycle - Statuses, each lab testing modality has the following format

[HIGH-LEVEL STATUS].[TEST MODALITY].[LOW-LEVEL STATUS]

For each modality, there can be multiple low-level status, for Walk-in orders the possible low-level status are:

• ordered: Vital received the order, stored it into our system, and started processing it asynchronously.
• requisition_created: An order requisition form was validated and created with the partner laboratory, making the order available to be carried out.
• partial_results: The laboratory has made partial results available.
• completed: The laboratory processed the blood sample and final results are available.
• cancelled: The order was cancelled by either the patient, Vital or you.

The Finite State Machine that defines the possible transitions for the low-level statuses described above is illustrated in the following diagram.
