After we arrived and did some work on our presentations for Thursday, Dr. Pandi showed us the analytical program he uses to check the drug concentrations in the patient samples. The program uses the results from each patient from the LCMS machine and categorizes them by each of the 60 drugs tested. Dr. Pandi then went through and checked the peaks graphed by the program for every patient, afterwards moving on to the next drug. After showing us the data points to consider and going through the first 15-20 drugs, he let us each analyze ~10 drugs each. We had to make sure each patient sample matched the standard sample, as well as the retention time and relative intensity, that way each positive, negative, and false positive could be identified at a rapid rate.
