Abstract: Methods, systems and apparatus for the tracking and managing of biological samples. A provider may check-in or register a patient at a provider facility. A sample tube may be registered to the patient, and a biological sample may be collected. The provider aggregates a plurality of sample tubes into cells of a rack. The provider then captures an image of the rack. A computer vision operation may be performed to isolate and identify a QR code affixed to the lid of each sample tube. The identified sample tubes are registered to the rack in which they are held, and the rack transferred to a destination lab. The same computer vision operation may be performed upon receipt of the rack. The samples may then be transferred to a sample plate. The samples are transferred from a cell in the rack to a corresponding well in the sample plate.
