Abstract
The present invention is directed to a method and apparatus for detecting foam in a specimen container. The method includes the following steps: transporting a specimen container into a locator well; centering the specimen container in the locator well; rotating the specimen container around a vertical axis in the locator well; imaging the specimen container during the rotation; analyzing an image of the specimen container captured during the rotation; and detecting foam in the specimen container based on the analysis of the image. An apparatus configured to perform the steps is also provided. The method and apparatus may be used in conjunction with a system for automatically determining whether a sample is positive for microorganism growth.
