Abstract
Systems and methods for determining the presence and/or amount of analytes in a fluid sample are described.
Claims20
An optical reader for performing a diagnostic test on a test sample, comprising:
- a cassette receiving member configured to receive at least one cassette comprising a lateral flow strip with a test sample received thereon,
- an excitation member positioned to direct excitation energy towards the at least one cassette when the at least one cassette is received by the cassette receiving member, the excitation member comprising a flashlamp that is configured to emit a single flash for each diagnostic test;
- and
- an imaging system configured to capture an image of a viewing area, the viewing area comprising at least a portion of the at least one cassette.
