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.
Claims21
A system comprising:
- a processor;
- memory coupled to the processor having stored therein a local testing database, the local testing database including a plurality of test configuration profiles, wherein each of the plurality of test configuration profiles specifies an intensity threshold value denoting a positive test result for an associated test type;
- a carrier for receiving a cassette containing a lateral flow assay (“LFA”) strip;
- an LFA strip reader coupled to the processor for obtaining an LFA strip image, the LFA strip reader obtaining the image of the LFA strip and at least a partial image of the cassette, regardless of alignment of the cassette within the carrier, and transmitting the LFA strip image to the processor;
- the processor further configured to determine an LFA test result based on comparing an intensity value of a portion of the LFA strip image to the intensity threshold value for an associated test configuration profile for the test type of the LFA strip;
- and
- the processor further configured to provide the LFA test result on an indication panel.
A system comprising:
- a processor;
- memory coupled to the processor for storing having stored therein a local testing database having a plurality of test configuration profiles with each test configuration profile including an intensity threshold value denoting a positive test result for an associated test type;
- 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, to yield an LFA strip image, and a visual feature of the cassette and transmitting the LFA strip image and the visual feature to the processor;
- the processor further configured to identify a first test configuration profile based on the visual feature and determine 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 for the test type of the LFA strip.
A testing device for testing for disease, the testing device comprising:
- a processor;
- memory coupled to the processor having stored therein a local testing database, the local testing database including a plurality of test configuration profiles for a plurality of diseases, wherein a each of the test configuration profile specifies an intensity threshold value denoting a positive test result for one of the plurality of diseases;
- a carrier for receiving a cassette containing a lateral flow assay (“LFA”) strip for a first disease;
- an LFA strip reader coupled to the processor for reading the LFA strip, regardless of alignment of the cassette within the carrier, yielding an LFA strip image, and transmitting the LFA strip image to the processor;
- the processor further configured to determine an LFA test result based on comparing an intensity value of a portion of the LFA strip image to the intensity threshold value from the test configuration profile for the first disease;
- and
- the processor further configured to provide the LFA test result on an indication panel on the testing device.
