The present invention is directed to a system and method for transferring specimen containers between detection instruments. The method may include transporting a specimen container in a locator well to a container transfer station in a first automated detection apparatus; sensing the specimen container at the container transfer station using a first sensor; transferring the specimen container from the container transfer station of the first automated microbial detection apparatus to an automated loading mechanism of a second automated microbial detection apparatus; detecting that the specimen container is positioned over the automated loading mechanism of the second automated microbial detection apparatus using a second sensor; and releasing the specimen container onto the automated loading mechanism of the second automated microbial detection apparatus.
