Table 1. Comparison of results for samples extracted with the MagNA Pure and the Qiagen BioRobot 9604. a

5 (heterozygotes) 8.8 0.12 (1.4%) 9.7 2.0 (20%) Allele areas (A1/A2) 5 (heterozygotes) 1.1 0.2 (1.4%) 2.5 1.3 (54%) a DNA yields and purity were determined by spectroscopy. Extraction failure rate was determined by factor V, factor II, hemochromatosis, and MTHFR LightCycler assays. Reproducibility studies (within run) were performed using the factor V assay and different samples. The performance of MagNA Pure-extracted samples met or exceeded the standards from the Qiagen-extracted samples for all criteria tested.
