A method for performing a screening includes illuminating a sample with light from a screen of a system at a first wavelength while the system is at a predetermined position with respect to the sample. The method also includes capturing a first image of the sample using a camera of the system while the system is at the predetermined position and the sample is illuminated with the light at the first wavelength. The method also includes illuminating the sample with the light from the screen at a second wavelength while the system is at the predetermined position. The method also includes capturing a second image of the sample using the camera while the system is at the predetermined position and the sample is illuminated with the light at the second wavelength. The method also includes combining the first and second images to produce a multispectral image.

Capturing multi-spectral images

A method for detecting a molecule in a sample includes applying a first filter to an image at a first wavelength. The method also includes applying a second filter to the image at a second wavelength. The method also includes applying a third filter to the image at a third wavelength. The first, second, and third wavelengths are within a predetermined wavelength range, and wherein first, second, and third wavelengths are different from one another. The method also includes detecting a spectral signature for the molecule in the sample in the image after the first, second, and third filters are applied to the image. The method also includes determining whether the molecule is present in the sample based at least partially upon the detected spectral signature.

Camera-based hemoglobin detection

An analyzing platform may obtain a first image of a liquid in a receptacle. The analyzing platform may analyze the first image to determine a first set of visual characteristics concerning the liquid. The analyzing platform may obtain a second image of a rectal sample in the liquid in the receptacle, wherein the rectal sample originated from a bowel of a subject. The analyzing platform may analyze the second image to determine a second set of visual characteristics concerning the rectal sample. The analyzing platform may determine, based on the first set of visual characteristics and the second set of visual characteristics, rectal sample information. The analyzing platform may cause one or more actions to be performed based on the rectal sample information.
