Product Description
WE HAVE COMPARED VIAGUARD'S NEW STATE OF THE ART NON- INVASIVE BLOOD SAMPLE COLLECTION TEST TO OLDER METHODS, SOME STILL IN USE, THAT USE A FEW DROPS OF BLOOD ON A CARD.
THE RESULTS ARE AS FOLLOWS:
VIAGUARD NON INVASIVE BLOOD SAMPLE COLLECTION - 98.7% ACCURACY
OLDER BLOOD SPOT ON A CARD COLLECTION METHODS - 71.4 ACCURACY
THE VIAGUARD SYSYEM IS 40% MORE ACCURATE, AND BOTH TESTS COST ABOUT THE SAME.
IF YOU HAVE TO PAY TO HAVE A BLOOD SAMPLE TAKEN, VIAGUARD WILL REBATE THAT COST UP TO $40.00 PER COLLECTION, JUST ADVISE US
The gender of a fetus can be determined with 100% 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. 100% results are obtained using a small blood sample taken from the mothers arm using the vacutainer tube we supply. The sample can be easily taken at any medical lab in a few minutes , and is stabilized in the tube for returning to us by courier or mail
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.
