Amended Plasma Dilution Series Extraction Results.

A) qPCR results from extracted samples containing fragmented male DNA ranging from 100 to 1 ng and total DNA including 200 ng fragmented female DNA per sample for TruTip (◊ and ■) and Qiagen (Δ and X) respectively, n=3 extractions each with n=3 per sample for PCR. Error bars indicate ± one standard deviation. B) Percent bias from actual % fetal DNA recovery for TruTip (◊) and Qiagen (Δ) over the same range of sample inputs (100-1 ng male and 200 ng female).
