Report to capture patients with certain lab tests

81 Views Last edit Aug 24, 2017 at 03:21 PM 2 rev

I am trying to write a report to capture only the patients that had certain lab tests done. So for example I need everyone that had test A and they also had tests B,C,D. If I just use the in function of in [A,B,C,D] then I get everyone that had one those tests not the patients that had A and B,C or D. What is the best way to write this in Crystal Reports ?
