Abstract

Objective: To evaluate the efficiency of cell free fetal DNA (cffDNA) recovery of 2 commercial kits QIAamp Circulating Nucleic Acid and MagMAX Circulating DNA. Subjects and research methods: plasma samples of pregnant women with male fetuses. The study compared the efficiency of cfDNA recovery of two extraction procedures based on fetal fraction (FF) by quantitative real-time PCR. Result: The average FF of the QIAamp kit was 7.93%; The average FF of the MagMAX kit was 6.23%. The mean FF of QIAamp was 1.27 times higher than that of MagMAX, but the difference was not significant (p=0.33). Conclusion: There was no difference in the cffDNA recovery of the QIAamp kit and the MagMAX kit.
