1. A method, comprising:
receiving, by a processor, an image of a sample collection device captured by an image sensor;
analyzing, by the processor, the image of the sample collection device to determine whether the sample collection device includes a sufficient amount of fluid sample, wherein analyzing the image of the sample collection device includes analyzing the image of the sample collection device utilizing a first image analysis algorithm, wherein utilizing the first image analysis algorithm includes:
applying one or more modifications to the image of the sample collection device, wherein one of the one or more modifications includes applying perspective correction to the image of the sample collection device;
determining a plurality of objects included in the image of the sample collection device;
identifying one or more areas of the image expected to include one or more objects;
filtering a first subset of the plurality of objects from the image of the sample collection device to produce a second subset of one or more remaining objects of the plurality of objects; and
determining an area associated with the fluid sample in the second subset of one or more remaining objects of the modified image of the sample collection device; and
validating, by the processor, the image of the sample collection device based on a result of the image analysis including by comparing the determined area associated with the fluid sample in the second subset of the one or more remaining objects of the modified image of the sample collection device to a total area associated with the sample collection device.
