a Distribution of % β-globin levels (total DNA) based on fragment size in maternal plasma. Graph represents 31 pregnant women divided by first (n = 12; 1T), second (n = 12; 2T), and third (n = 7; 3T) trimesters. Plasma controls included non-pregnant women (n = 8) and adult men (n = 10). No significant difference was found among groups (p > 0.1). b Distribution of % DYS1 (fetal DNA) based on fragment size in maternal plasma. Graph represents 16 pregnant women divided by first (n = 6; 1T), second (n = 6; 2T), and third (n = 4; 3T) trimesters. Plasma controls included adult men (n = 10). Significant difference in DYS1 levels observed at 100–300 bp fragment size between all trimesters (p = 0.0009).
