Abstract
CffDNA, from 344 non-smoking, 38 smoking and 33 ex-smoking pregnant women at 11 + 0–13 + 6 gestational weeks, was extracted and quantified by the multicopy DYS14, as the fetal DNA marker and using the quantitative real-time PCR 7300 detection system. The smoking habit was based on maternal self-report, confirmed by cotinine levels and male fetuses were verified by phenotype at birth. The genders of newborns were compared with DYS14-cffDNA analysis, achieving a 100% diagnostic accuracy of the test. A total of 177 non-smokers, 18 smokers and 22 ex-smoker pregnancies with male fetuses were identified by the cffDNA concentration. Results showed that smoking status was not associated with different amounts of DYS14-cffDNA (p = 0.159), suggesting the possibility of offering cffDNA testing to all pregnant women, even if they are active smokers or ex-smokers, and the test can be unadjusted for smoking status.
