Regression analysis comparing high-performance liquid chromatography and flow cytometry performances in 130 samples. The correlation between the percentage of HbF (HbF%) detected by HPLC and the percentage of fetal RBCS (fRBCs%) detected by FC was evaluated. Plot represents, for each sample, values obtained with HPLC (Y axis) versus FC (X axis). The regression analysis showed a linear correlation, with a positive slope and R2 value > 0.90.
