Ok so I had the job of my dreams...Workded really hard, really excited. Getting ready to start BSN school in June. Had my premployment drug screen. They called me back several week later, told me it was diluted and come back in. Got ready went in about 1 hour. Went to orientation on Monday, pulled out of orientation. My test was to dilatuted would not offer me a job... My sp gravity was 1.002 my creat was 12.4 on the first and 10.1 on the second. These were done weeks apart. When i went to my doctor he says my creat was .8 this was about 1 week after the last test done. How could this be so high?? I was out at the bars with some friends during the holiday but this seems really high. Just looking for answers. Help.....
