Appl. No.:

17/403893

Inventors:

Deborah Ann Payne - Lakewood CO, US

International Classification:

A61F 13/38
A61B 10/00
A61F 13/84

Abstract:

A collection device for collecting and preserving biological material. A longitudinal shaft is provided with a proximal end and a distal end. An absorbent solid matrix having at least one layer of chemically impregnated filter paper is affixed to the distal end of the shaft. The absorbent solid matrix consists of chemically impregnated filter paper and can have portions separated by perforations, or an inner core and a separable, overlapping outer layer. The absorbent solid matrix has a configuration that may include nubs, individual ribs, helical, filaments, and radial protrusions. Also disclosed is a tampon-like collection device for delivering an absorbent solid matrix.

Abstract:

A method of testing for the presence of an infectious biomarker indicating bacteria, fungi, parasites, or viruses. A test sample comprising cellular and non-cellular material is collected from a patient, the test sample having a first amount of at least one infectious biomarker and a second amount of a host biomarker. The amount of the infectious biomarker(s) in the test sample is determined as is the amount of the host biomarker. The amount of infectious biomarker(s) in the test sample is normalized as a function of the amount of host biomarker therein. The normalizing step is a ratio of the first amount of the infectious biomarker(s) to the second amount of the host biomarker. The test sample is positive for a disease associated with the infectious biomarker(s) if the ratio is above a predetermined value. The normalized result is tracked over time to assess therapeutic response to treatment. A database is provided for interpreting results collected from the patient and for determining predictive sensitivity, specificity, and diagnostic accuracy.
