Methods of identifying a characteristic of a clinical analysis specimen or a sample container containing the specimen are disclosed. The methods include moving the sample container along a track while causing translation and rotation of the sample container, and capturing two or more images of the sample container during the translation and rotation. The track may have one or more moveable belts contacting a carrier to rotate and translate the carrier holding the sample container. Image analysis may be used to read a barcode label of the sample container, determine HIL, and/or physical characteristics of the sample container. Apparatus for carrying out the method are described, as are other aspects.
