Abstract
A system having a processor and memory coupled to the processor is provided. The memory stores a local testing database having a test configuration profile with the test configuration profile having an intensity threshold value denoting a positive test result. The system includes a carrier for receiving a cassette containing a lateral flow assay (“LFA”) strip and an LFA strip reader coupled to the processor for reading the LFA strip regardless of alignment of the cassette within the carrier and for transmitting an LFA strip image to the processor. The processor determines an LFA test result based on comparing an intensity value of a portion of the LFA strip image to the intensity threshold value and provides the LFA test result on an indication panel.
Claims20
A system comprising:
- a processor;
- memory coupled to the processor for storing a local testing database having a test configuration profile with the test configuration profile having an intensity threshold value denoting a positive test result;
- a carrier for receiving a cassette containing a lateral flow assay (“LFA”) strip;
- and
- an LFA strip reader coupled to the processor for reading the LFA strip regardless of alignment of the cassette within the carrier and transmitting an LFA strip image to the processor,
- wherein the processor determines an LFA test result based on comparing an intensity value of a portion of the LFA strip image to the intensity threshold value,
- and further wherein the processor provides the LFA test result on an indication panel.
A system comprising:
- a processor;
- memory coupled to the processor for storing a local testing database having a plurality of test configuration profiles with each test configuration profile having an intensity threshold value denoting a positive test result;
- a carrier for receiving a cassette containing a lateral flow assay (“LFA”) strip;
- and
- an LFA strip reader coupled to the processor for reading the LFA strip and a visual feature of the cassette and transmitting an LFA strip image and the visual feature to the processor,
- wherein the processor determines a first test configuration profile based on the visual feature and determines an LFA test result based on comparing an intensity value of a portion of the LFA strip image to the intensity threshold value of the first test configuration profile,
- and further wherein the processor provides the LFA test result on an indication panel.
A method of building a configuration profile for a cassette comprising:
- receiving, by a processor, test information for a cassette,
- receiving, by the processor, an image of the cassette;
- receiving, by the processor, light settings for a plurality of light sources;
- storing, by the processor, the light settings for the cassette in the configuration profile;
- and
- receiving, by the processor, a threshold value for a positive test result for the cassette and storing the threshold value in the configuration profile.
