I Never Left Safety to Voice Alone.

01 / BEFORE QR CODES

Before QR codes

Originally, a test request form received an ID number and the same numbered label had to be attached to every required tube. Verification meant checking that the patient, the requested tests, the tube types, and the labels all agreed.

Later, customers began submitting tubes already carrying unique QR labels. After the order was entered into the AS/400, the system displayed that order and the operator selected and arranged the matching tubes.

02 / ONE CODE FOR ONE PHYSICAL TUBE

One code for one physical tube

The QR code uniquely identified each tube and also carried its tube-type information. Reading it connected the physical object in the operator’s hand to the logical order in IBM i.

A later process used that QR identity to laser-mark the correct internal ID on the tube. The QR was therefore not a decorative shortcut: it was the bridge between the submitted specimen and the laboratory system.

03 / VOICE TELLS; QR PROVES

Voice tells; QR proves

Speech synthesis told the operator which patient and tube to find. Speech recognition accepted the operator’s response. But the barcode reader verified the actual tube.

Voice moved the workflow forward. QR anchored it to physical reality.

If recognition was imperfect, the specimen identity was still not left to sound alone. Redundancy was intentional: one interface supported human movement, and the other protected traceability.
