Fetal DNA has been found to be constantly circulating in the maternal blood in relatively high concentrations. The concentration of fetal DNA ranges from 3% to 12% of the total DNA found in the mother sample; which is a sufficient quantity for our testing purposes. In fact, many research groups have confirmed that there is a sensitivity of approximately 100% in the detection of fetal DNA from maternal plasma.
