The extensive research done by Viaguard using its exclusive DNAffirm technology in developing the Jack or Jill prenatal gender test has been essentially confirmed by recently published studies done at various medical schools.
The conclusion of the studies was that in 6500 tests performed on pregnant women the prenatal gender determination was 99.8% accurate.
You can have complete confidence in Viaguard's Jack or Jill prenatal gender test which is done using a few drops of blood dripped onto our special collection strip from the mother’s fingerprick, after 7 weeks of gestation.
Non-invasive procedures
The gender of a fetus can be determined with 98% accuracy after approximately 7 weeks of gestation (10 weeks after last missed period). At this stage of pregnancy, the maternal blood carries sufficient fetal DNA for identification of the gender of the fetus.
Gender identification is based on the specific identification of the Y chromosome which indicates that the fetus is absolutely a male, absence of the Y chromosome means a female fetus.
Viaguard DNAffirm Technology is the state-of-the-art for precision determination of prenatal gender. The collection kit allows the mother to use our sterile disposable lancet to pinprick her fingertip and allow 2 or 3 drops of blood to be collected on our enclosed membrane card which is then sent to us. The maternal blood carries fetal DNA which allows us to determine with up to 98% accuracy the gender of the fetus.

The Viaguard genetic non-invasive gender determination test has evolved from work done in 1997 when Lo et al first described the presence of fetal DNA in material plasma and serum. The cell free fetal DNA offered an important path for non-invasive prenatal gender determination. Based on a PCR assay, Viaguard has determined that the concentration of fetal DNA in maternal plasma in the first trimester and particularly after 7 weeks of gestation was about 3.4% and it is estimated that a mean of 24.4 copies of fetal DNA circulates per ml. of maternal plasma. At this level there is almost 100% precision in identifying the Y chromosome and establishing fetal gender.
