Ct scan results

Hi, hubby has been looking very pale for over a month before he went to see our gp,with his recent history of peeing blood she decided to do a blood test. Results came back and he was chronic anaemic, since then he’s had one iron infusion and a ct scan as on an ultrasound they couldn’t find the outline of one if his kidneys, but now waiting on results. This was only a week ago but should we have results back by now? Also does anyone have any advice on what this could be
