second xray needs to be done????

[Mel&Lal 12]

Not sure where to ask for help on this subject but I am sure somebody will come along and stick it where it needs to go. Well in July my husband had his medical done and there was some issue with his xray, so he needed to get a spectrum test done. He received a call from the hospital that did the xray on Oct 5 saying that his results are in and it was negative, but he was told that they will give him a call back and set up a second xray to get done. When we had to do medical from our denied K1 visa we had to have this spectrum test done but was never requested a second xray. We are stuck now still waiting for the hospital to call him and we cant set up his interview. Had anybody else had to have a second xray done before visa interview? Since he had his results back from the spectrum test is it ok to say we can set up an interview date? Thanks for the help.
