Abstract: A kit for detecting upper respiratory conditions. The kit includes a container for collecting nasal secretions. The kit further comprises a means for providing a differential readout upon contact with the nasal secretions.

Abstract: A method for detecting upper respiratory conditions. The method includes implementation of a device upon which are fixed discrete indicators of pH, protein content, nitrite content and/or leukocyte esterase activity.

Abstract: A device for detecting upper respiratory conditions. The device includes a support upon which are fixed discrete indicators of pH, protein content, nitrite content and/or leukocyte esterase activity. The device further comprises a container to facilitate collection of nasal secretion sample in order to test for different upper respiratory conditions.

Abstract: A device for collecting nasal secretions that comprises a container designed to fit about a patient's nose. The device comprises a ventilation means to allow the patient to blow their nose into the container while preventing the undesired dispersion of nasal secretion onto the patient and their surrounding environment.

Abstract: A method and device for rapidly, non-invasively and inexpensively differentiating between allergic rhinitis, upper respiratory tract viral infection and bacterial sinusitis, comprising a support strip upon which is fixed discrete indicators of pH, protein content, nitrite content, leukocyte esterase activity, and eosinophil content or other measure of a substance found in allergic secretions, such as TAME esterase, of a sample with which said reagent test strip is contacted. Contact of a nasal secretion with the device of this invention permits differentiation between allergic, bacterial and viral conditions, based on pH, protein content, leukocyte esterase activity, nitrite content, eosinophil content and TAME esterase activity. The invention further provides a novel means for collecting nasal secretions to facilitate differential diagnosis of sinusitis, upper respiratory tract viral infection and allergic rhinitis.
