Fig. 2. Method comparison for HISCL-5000 immunoassay and UniCel DxI-800 immunoassay for PSA (N=363, R²=0.99). (A) Measured range was from 0.01 to 541.56 ng/mL. The slope (95% confidence interval) was 0.92 (0.91-0.93) for PSA. The intercept (95% confidence interval) was -1.06 (-1.71~-0.40). (B) Bland-Altman plot shows the mean difference and upper and lower limit of 1.96 SD.
