(a)R2 for calibration curve (a measure of goodness of fit of the least squares linear regression); values are mean of 10 calibration curves. (b)Values are mean of 10 calibration curves; units are peak area ratio (μg/ml)−1. (c)Precision (determined in an authentic volunteer sample, n = 6 replicate analyses); value is relative standard deviation (RSD). (d)Precision (determined in an authentic volunteer sample, n = 10 analyses on different days); value is RSD. L: low-concentration quality control sample; M: medium-concentration quality control sample; H: high-concentration quality control sample; LOD: limit of detection; LOQ: limit of quantification. |
