3.1.3. Repeatability, intermediate precision and accuracy
The coefficients of variation (CVs) obtained were lower than 10% for all substances at the concentrations studied (repeatability CV < 6.4%, intermediate precision CV < 7.0%) in accordance with the criteria normally accepted in bioanalytical method validation. As regards accuracy, the mean RE (bias) was within +-10% of the nominal concentration, fulfilling the aforementioned criteria. All the results obtained for repeatability, precision and accuracy assays are presented in Table 2.
