Abstract: Methods and devices for analyzing blood sample volumes are provided. In particular, the disclosure provides a method for estimating the volume of a blood sample on a substrate including the steps of acquiring an image of the blood sample. A coverage or area of the blood sample may be obtained from the image and compared to a standard curve to obtain a volume estimate of the blood sample. The disclosure also proves a device for scanning one or more blood samples on a substrate. The device includes three layers that may be assembled to hold multiple samples between the layers. The device also includes labels and may be disassembled for decontamination and reloading of samples.
