Concomitant medications experiment in method validation [Bioanalytics]
❝ We add the concomitant medications to LLOQ of analyte and compare against the calibration standard.
For concomitant medications, you compare the LLOQ (spiked with concomitant medications) with Blank Samples (also spiked with concomitant medications) and calculate the signal to noise ratio (or %interference). Response of interfering peaks at the retention time of the analyte for the blank samples should be less than 20% of the lower limit of quantification for the analyte and 5% for the internal standard.
❝ Any additional experiment has to be performed to evaluate its effect.
Precision and Accuracy needs to be evaluated for the range of CC standards (spiked with the concomitant medications)
Incurred Sample Reanalysis also give an insight on the effect of concomitant medications.
These are my thoughts.
