Abstract
Methods are provided for operating an instrument to test samples suspected of containing a target pathogen in a near patient point of care environment. One embodiment of the method includes adding an identifying mark to a point of care cartridge and inserting the cartridge into an instrument. Additionally, interaction with a graphical user interface on the instrument can initiate the test sequence or eject the cartridge.
Claims36
A method of operating an instrument for testing a sample suspected of containing a target pathogen, comprising:
- loading the sample suspected of containing the target pathogen into a sample port assembly of a cartridge;
- adding an identifying mark to a patient label area of the cartridge;
- inserting the cartridge into an opening of the instrument until the cartridge is positioned within the instrument with the identifying mark within a field of view of a label imaging camera;
- observing on a graphical user interface of the instrument an indication of a type of test to be performed on the cartridge and an image of the identifying mark on the patient label area of the cartridge;
- interacting with the graphical user interface of the instrument to eject the cartridge if the image of the identifying mark or the indication of the type of test is incorrect;
- and
- removing the cartridge from the opening of the instrument after the cartridge is automatically ejected from the opening.

A method of testing a sample suspected of containing a target pathogen, comprising:
- inserting the sample suspected of containing the target pathogen into a point of care cartridge;
- placing an identifying mark on a patient label section of the point of care cartridge;
- inserting the point of care cartridge into an opening of a point of care instrument until the patient label section of the point of care cartridge is within a field of view of a label imaging camera within an interior portion of the point of care instrument;
- observing on a graphical user interface of the point of care instrument an image of the patient label section captured by the label imaging camera;
- and
- performing only a single interaction with the point of care instrument to observe on the graphical user interface, adjacent to the image of the patient label section, a single indicator representing a result of a testing sequence indicating a presence of the target pathogen, an absence of the target pathogen, or a quantity of the target pathogen in the sample.
