1. An apparatus comprising:
a bag tray defining at least a first surface configured to accommodate a dialysate drain bag on top of the first surface;
a device placement area defined by an opening in the first surface configured to accommodate a dialysate analysis device, the dialysate analysis device being separate from and replaceable with respect to the first surface, such that when the dialysate drain bag is on top of the first surface and the dialysate analysis device is placed in the device placement area, a light sensor of the dialysate analysis device is positioned planar to the first surface and underneath the dialysate drain bag, the light sensor being configured to sense light passing through the dialysate drain bag; and
a light-emitting device positioned above the bag tray and the device placement area, and configured to emit light through the dialysate drain bag toward the light sensor of the dialysate analysis device, the light-emitting device configured to operate responsive to instructions transmitted by the dialysate analysis device.
