ABSTRACT:
According to the present invention, there is disclosed a method of stabilizing the output signal of a system that detects microbiological growth in a sealed sample container that contains a sample which may contain an unknown microorganism. One embodiment relates to a method of providing a sealed sample container which contains a fluid mixture of a culture broth, the sample, and at least one poising agent for stabilizing the base line pressure within a headspace above the fluid mixture in the sample container. By monitoring pressure changes within the headspace of the sealed sample container, the presence of microbiological growth within the sealed sample container as a function of the change of the pressure in the headspace is indicated.
