Instrument parameter determination based on Sample Tube Identification

A system comprising,

• a designated position to receive a container,
• a camera to capture one or more images of the container in the designated position, and
• a convolutional neural network (CNN) to receive the one or more images of the container, the CNN for determining boundaries of separated layers of a material located in the container for determining hematocrit based on one or more of layers, liquid levels or liquid volumes percentage based on the boundaries determined from the one or more images.
