Method Verification
Prior to commencing the study, both methods were evaluated to verify that the presence of each active substance did not interfere with the quantitation of the other in both 0.9%w/v saline and Ringer’s Lactate solutions (selectivity). Additional method verification was undertaken to demonstrate that the validated parameters, accuracy, precision, linearity, carryover and matrix effect, were not affected by the mixing of TXA and oxytocin.
