DEFINITION :  The Pharmacokinetics Concentration (PC) domain records measurements of drug concentration in the subject’s blood or other biological samples. These data are essential to study how the drug is absorbed, distributed, metabolized, and excreted.

PURPOSE : To track and analyze the concentration levels of the investigational drug in biological samples over time, providing insight into the drug’s pharmacokinetics.

STRUCTURE : One record per analyte per planned time point number per time point reference per visit per subject

TOPIC : PCTESTCD

KEY VARIABLES : STUDYID, USUBJID, PCTESTCD, VISITNUM, PCTPTREF, PCTPTNUM
