After years of intermediate success and failure, the interest in fetal cells circulating in maternal blood has come full circle. Recent advances in single fetal cell genetic analyses have invigorated interest in fetal cells for prenatal diagnostics. However, for this interest to sustain, we propose a list of best practices that have their origins in the lessons learned from past successes and failures.
