3.5. Analytical performance and method validation
The proposed analytical multi-component method was evaluated
in terms of linearity, recovery, accuracy and precision intraand
inter-day, selectivity and sensitivity. Blank plasmawas assessed
in six different batches of plasma samples by analyzing blanks and
spiked samples at LOQ levels. The calibration curves were made
under optimized conditions following the proposed methodology,
which was described above. Blank plasma were spiked with ARV
standards achieving different concentration levels [31,32]. No significant
chromatographic signals of endogenous ARV were
