Apparatus and methods are described for use with feces of a subject that is disposed within a toilet bowl (23), and an output device (32). One or more light sensors (60, 62, 64, 66) receive light from the toilet bowl, while the feces are disposed within the toilet bowl. A computer processor (44) analyzes the received light, and, in response thereto, determines that there is a presence of blood within the feces, and determines a source of the blood from within the subject's gastrointestinal tract. The computer processor (44) generates an output on the output device (32), at least partially in response thereto. Other applications are also described.

The disclosed apparatus, systems and methods relate to devices, systems and methods for the collection of bodily fluids. The collector can make use of microfluidic networks connected to collection sites on the skin of a subject to gather and shuttle blood into a removable cartridge. The collected fluid is supplied to substrate for drying, storage and transport.

The present invention provides means with which bile acids, phenols, indoles and organic acids contained in a sample can be stably preserved without cryopreservation of the sample. A sample preservation solution of the present invention is a sample preservation solution used for analyzing at least one component selected from the group consisting of bile acids, phenols, indoles and organic acids contained in a biological or environmental sample, containing at least the following (A) and (B): (A) condensed phosphate or polyoxyethylene sorbitan alkylate; and (B) guanidinium thiocyanate, Tris-HCl (pH 7 to 9), and EDTA.

The present disclosure relates to systems and methods for assessing the status of colon cleansing. In particular, the present disclosure relates to systems and methods to determine completion of colon preparation in subjects prior to a gastrointestinal procedure in real time.

A method and system for analyzing and/or estimating intestinal microflora of a subject. A digital image of a sample of feces of the subject is received by one or more processors. The digital image and/or one or more features extracted from the digital image is provided as input to a trained machine learning model which is configured to output a classification based on said input digital image and/or one or more features extracted from the digital image. Data indicative of one or more properties of the intestinal microflora of the subject based on the output image classification is determined by the one or more processors.

The present invention discloses, inter alia, swab, kit and a case, disclose a swab as defined above, administrable either or both into and onto a sample in a method comprising steps of providing the pouch-like envelope (1) with the opening (2), the inner surface (1i) and the at least one external surface (1e) with the at last one swabbing portion; inserting a handle into the swabbing portion; applying the swabbing portion either or both onto and into the substance; in-out rolling up the envelope so that the external portion hereto applied either or both onto and into the substance is position within the envelope; wherein at least one of the following s held true: the envelope characterized as a sleeve-like or sock-like elongated member having a main longitudinal axis, configured to be in-out rolled-up along the main longitudinal axis; and the envelope characterized as flexible pouch-like envelope, further characterized by being width-wise squeezable along an axis perpendicular to the main longitudinal axis thereby tightly encapsulated within at least two external case's walls. The present invention discloses a method for both sampling a substance and storing the same, characterized by steps: providing a pouch-like envelope (1), configured to be in-out rolled-up having an opening (2); the pouch comprises an inner surface (1i); and at least one external surface (1e) with at last one swabbing portion (3); the envelope either or both (a) characterized as a sleeve-like or sock-like elongated member having a main longitudinal axis, configured to be in-out rolled-up along the main longitudinal axis; and (b) flexible pouch-like envelope, characterized by being width-wise squeezable along an axis perpendicular to the main longitudinal axis thereby tightly encapsulated within two case's walls; inserting a handle into the swabbing portion; applying the swabbing portion either or both onto and into the substance; in-out rolling up the envelope so that the external portion hereto applied either or both onto and into the substance is position within the envelope; wherein at least one of the following is held true: the envelope characterized as a sleeve-like or sock-like elongated member having a main longitudinal axis, configured to be in-out rolled-up along the main longitudinal axis; and the envelope characterized as flexible pouch-like envelope, further characterized by being width-wise squeezable along an axis perpendicular to the main longitudinal axis thereby tightly encapsulated within at least two external case's walls.

Apparatus and methods are described for use with a bodily emission of a subject that is disposed within a toilet bowl. While the bodily emission is disposed within the toilet bowl, light is received from the toilet bowl using one or more light sensors. Using a computer processor, intensities of at least two spectral bands that are within a range of 530 nm to 785 nm are determined, by analyzing the received light, and a ratio of the intensities of the two spectral bands is determined. In response thereto, the computer processor determines that there is a presence of blood within the bodily emission. The computer processor generates an output on an output device, at least partially in response thereto. Other applications are also described.

The invention relates to a stool sample device [A′] for collecting a stool sample from a region of a human rectum, characterised in that it comprises an outer part and an inner part, wherein the outer part comprises an outer unit [G″], wherein an inner unit [E″] is mounted, further wherein the outer unit [G″] has a round tip and comprises openings for collecting sample; and the inner part comprises the inner unit [E″] fitted with gaskets [D″], further wherein the inner unit [E″] is equipped with a spiral-shaped part or snail placed at the tip end relative to the outer unit [G″] and with a handle for turning [B″] and pulling [C″] at the opposite end relative to the spiral-shaped part or snail, a first gasket [D″] is placed at the tip end of the inner unit [E″], and a second gasket is placed at the opposite end of the inner unit [E″] relative to the spiral-shaped part or snail; wherein the inner unit [E″] can be turned and pulled back by the handle [B″, C″].

An analytical toilet comprising a bowl adapted to receive excreta; one or more conduits for transporting a sample from the bowl; one or more fluid sources in fluid connection with the one or more conduits; and one or more microfluidic chips, comprising at least one fluid inlet; at least one fluid outlet; and a sensor configured to detect at least one property of an excreta sample is disclosed.

The invention relates to cell sampling devices. In particular, the present invention relates to ingestible cell sampling devices for sampling cells in a subject, and methods of use for detecting abnormalities in a subject using the same.
