  • Publication number: 20220162714
    Abstract: The use of Nucleic Acid Amplification Technologies (NAATs) to rapidly copy a specific fragment of DNA from a few starting molecules has been used to determine the presence of that DNA in a sample. It is of importance for various applications including the identification of a pathogen in a clinical sample. The disclosed embodiments describe an apparatus, disc, methods, and a system for detecting microorganisms such as pathogenic viruses and bacterial rapidly.

  • Publication number: 20220081730
    Abstract: 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.

  • Publication number: 20220049321
    Abstract: The disclosed embodiments may be used, among others, to extract particles from blood. The particles may include pathogens, viruses, bacteria and other microorganisms present in mammalian blood. An embodiment of the disclosure relates to a system to detect one or more blood-borne pathogens. The exemplary system includes: a transfer assembly having a tube and a hallow needle, the hallow needle centrally located within the transfer assembly tube and configured to communicate a sample material therethrough; a lysing syringe to couple to the transfer assembly, the lysing syringe comprising one or more lysing reagent and a plunger activatable to receive the sample material through the transfer assembly; and a large volume concentrator (LVC) to sealingly couple to the lysing syringe and to separate at least one pathogen from the sample material, the LVC further comprising: a filter support, a membrane, a retainer and a threaded portion.

  • Publication number: 20200224260
    Abstract: The use of Nucleic Acid Amplification Technologies (NAATs) to rapidly copy a specific fragment of DNA from a few starting molecules has been used to determine the presence of that DNA in a sample. It is of importance for various applications including the identification of a pathogen in a clinical sample. Non-specific DNA amplification occurring in the absence of any input DNA template is frequently observed after many amplification cycles or in the case of isothermal amplification, with time. The disclosed embodiments describe the surprising finding that the amplification of primer-only artefacts is suppressed in reactions where a fraction of the oligos involved in the reaction contain 3? blocked terminal bases that cannot support extension by DNA polymerases.
