METHOD, SYSTEM AND APPARATUS FOR RESPIRATORY TESTING
The disclosure relates to method, system and apparatus for respiratory testing. In one implementation, a method for detecting one or more pathogens causing a respiratory infection includes the steps of: (1) combining a quantity of mucous sample from a patient with a fluidic reagent to form a test reagent, the mucous sample further comprising at least one pathogen; (2) filtering the test reagent through a large volume concentrator to obtain a filtered solution; and (3) introducing the filtered solution onto a disc having a plurality of test site, wherein each of the plurality of test sites further comprises at least one agent to bind with the at least one pathogen to detect presence or absence of an infection caused by the at least one pathogen. The mucus sample may be obtained from nasal, nasopharyngeal or throat regions of the patient.
