Methods, systems, and computer software for screening and assisting in screening biological specimens. Images of a biological specimen are obtained, and image data is generated from the images. Objects of interest (OOI) are identified from the image data. The OOIs are assigned to each of a plurality of fields of interest (FOIs), at least partially based on the assignment of OOIs to other FOIs. For example, OOIs that have not previously been assigned to other FOIs can be assigned to a selected FOI. In this manner, the OOIs can be grouped within the FOIs to maximize the number of OOIs included within FOIs, or alternatively, to minimize the number of FOIs required to include all of the OOIs. Once assignment of the OOIs is complete, a field of view (FOV) can be scanned relative to each FOI in order to present the OOIs to a technician, such as a cytotechnologist.

Method and system for organizing multiple objects of interest in field of interest

The present invention provides bioactive porous partition members for use in connection with studies or tests of the blood coagulation process, wherein the porous partition members have an aperture and have incorporated therein at least one agent capable of initiating blood coagulation or platelet aggregation.

Bioactive porous partition members

The present invention provides novel test cartridges for use in the assay of liquid samples and methods of carrying out such assays. These test cartridges are particularly useful in assays which include at least one step during which the sample to be assayed and one or more components of the assay system are kept separated by a pierceable member. The test cartridges comprise a housing through which the sample flows during the assay. The housing includes a holding chamber for holding the sample and a test chamber separated by a pierceable member having a cut therein. The test chamber further includes a partition member which has an opening therethrough and includes at least one reagent for the assay. A transfer member movably mounted in the test chamber can move towards and pierce the pierceable member by moving through the cut and contact the liquid sample in the holding chamber. When the transfer member has been moved towards and pierces the pierceable member to contact the liquid sample and a negative pressure is created in the test chamber, liquid sample moves through the transfer member, into the test chamber and through the opening in the partition member.

Combination reagent holding and test device

The present invention provides methods of using bioactive porous partition members for testing the blood coagulation process or platelet function, wherein the porous partition members have an aperture and have incorporated therein at least one agent capable of initiating blood coagulation or platelet aggregation.
