Size collection of smaller cfDNA as a whole cfDNA could notably increase the fetal fraction, but you will find few reports of using this process to diminish the untrue negative price for NIPT. In this research, nine false bad instances had been retrospectively analyzed by NIPT retesting and E-gel based size-selection NIPT additionally the fetal cfDNA fraction in maternal total cfDNA was evaluated by calculating the proportion of reads from chromosome Y. Fetal placenta karyotypes had been confirmed by CNVplex assays to analysis the reason why for false bad situations. For the 81,601 pregnancies just who underwent NIPT, nine false unfavorable situations (0.01%) had been found. Of eight retested situations, two (25%) had good NIPT retest results, and five (62.5%) had good size-selection NIPT results. For fetal cfDNA fraction, 100% instances had improvement after size-selection NIPT compared with the first NIPT and retest outcomes, and also the fetal cfDNA fraction growth proportion ranged from 99 to 359percent. For example twin pregnancy with one T18 fetus, dimensions selection enhanced the fetal cfDNA fraction to 23.10per cent, and effectively detected the T18 fetus in NIPT. Placental tissue analysis results for two situations indicated both had restricted placental mosaicism (CPM), that has been verified with size-selection NIPT. To conclude, size choice can substantially enrich the fetal cfDNA fraction and reduce steadily the untrue unfavorable price of NIPT, particularly for CPM and twin pregnancies.
