Analysis of retest reliability for pregnant women undergoing cfDNA testing with a no-call result.

In addition, pregnant women with a no-call result are at increased risk of adverse pregnancy outcomes. In conclusion, more attention should be given to pregnant women for whom a no-call cfDNA result is obtained.
