Non-invasive procedures are used in the vast majority of pre-natal paternity determinations because the procedures involve no risk to the fetus since there is no invasion of uterine/placental integrity. Viaguard's DNAffirm technology provides definitive pre-natal paternity determination using a small sample of maternal blood as a source of fetal DNA and buccal swabs from the potential father(s).
Viaguard noninvasive prenatal DNA testing uses cell free fetal DNA from the plasma of the mother- to- be. Circulating cell free fetal DNA which compises 3-13% of the cell free DNA in maternal blood is separated by Viaguard from all other blood constituents in about 4 days, and then the fetal DNA profile is determined and compared to the DNA profile of potential fathers.
The three simple step process is outlined below:
Maternal Venous Blood - safe and non-invasive
Viaguard's prenatal paternity testing is based on comparing the potential father(s) DNA, obtained by buccal swabs or other methods, to the DNA of the fetus as evidenced in fetal DNA material found in the maternal venous blood. Non-invasive testing is done on samples from anywhere in the world, using our exclusive Accu-stable collection system which we supply.
The placenta is a wall of tissue that forms inside the uterus during pregnancy, and is comprised of fetal cells.
The placenta enables the fetus to receive, during gestation, all the nutrients and oxygen needed for normal development. The fetal side of the placental barrier has an intricate network of thousands of minute blood vessels, which are in fact the fetal blood supply, which receives food and oxygen by diffusion from the maternal side of the placenta.
Research studies demonstrate that the placenta is not just a passive membrane, but serves a vital function in fetal brain development. The placenta synthesizes serotonin and releases it in the fetal blood supply where it travels to the fetal brain. This supply of serotonin is essential for fetal brain development and failure to provide this supply can result in later mental and physical problems in the child. Because the placenta is so important in brain development Viaguard strongly recommends the use of its safe and non-invasive maternal venus blood sample, drawn from the mother's arm and not the use of invasive technologies which may traumatize the placenta.
At no time do the maternal and fetal blood supply mix, and waste from the fetus diffuses through the placenta into the maternal blood supply. Included in this diffusion is fetal DNA, which is a normal component of maternal blood during gestation. Fetal DNA is found in cells that migrate, but the most important source is cell-free molecules of fetal DNA. These are formed during the development of the fetus and placenta, because there is a certain amount of cell lysis and apoptosis. It is this naked fetal DNA, once isolated, which is used in the Viaguard prenatal test for paternity determination.
TRUST VIAGUARDS EXPERIENCE AND CLINICAL PRECISION
AFTER 11 WEEKS OF GESTATION, SAMPLES CAN BE TAKEN BY ATTENDING AT OUR FACILITY, OR WE WILL MAKE ARRANGEMENMTS FOR SAMPLES TO BE TAKEN WHEREVER YOU LIVE, IN ANY COUNTRY, STATE OR PROVINCE. A CLINICALLY PRECISE DNA DETERMINATION OF PATERNIY IS AVAILABLE AT A TOTAL COST NEVER EXCEEDING $800.00. CALL US AT (416) 691-4167 or toll free at 1-877-842-4827TO DISCUSS YOUR CIRCUMSTANCES
We supply the laboratory with the specialized collection tubes to be used for this purpose and returned to us after the collected blood has been centrifuged to separate the maternal red blood cells from the plasma.
The plasma portion is rich in fetal DNA, which is stabilized and preserved in our special collection system. This fetal DNA is matched against the paternal DNA and yields a conclusive result. Complete cost of the test is $800.00.
Test includes maternal alpha-fetoprotein screening for spina bifida The American Pregnancy Association states "The benefit of screening is that 75% to 90% of babies with neural tube defects are detected

Paternal DNA Samples
As in all paternity testing, DNA samples are required from the potential father(s). They are usually acquired by obtaining paternal buccal swab samples using our kit or at our facility. Paternity samples can also be acquired without the potential father(s) knowledge using a variety of discreet DNA samples as listed below under the heading discrete prenatal paternity testing.
Discrete Prenatal Paternity Testing
There may be occasions when the mother to be does not want the potential father(s) to be aware of her prenatal paternity test. Viaguard performs many prenatal tests where only the mother to be is aware of the test.
DNA samples from the potential father(s) can be obtained from a variety of discreet sources including but not limited to:
Mucous (used Kleenex)
A spot of blood or any blood sample
Semen (used condom etc.)
Razor (including electric)
Cigarette butts (2 or more)
Saliva (on cups, envelopes etc.)
-ACCURACY WHEN SAMPLES ARE SUBMITTED FROM TWO POTENTIAL FATHERS - 97.2% (SECOND FATHER'S SAMPLE CAN BE ANY DISCREET SAMPLE SUCH AS A TOOTHBRUSH ETC.).
-ACCURACY WITH CHEEK SWAB SAMPLES FROM JUST ONE FATHER 96.3%
How the process works - Connecting the DNA from the fetus and the father(s)
DNA samples (buccal swabs or discrete sampls) are collected from the presumed biological parents and compared to the fetal DNA obtained from the plasma portion of the small amounts of venous blood sample from the mother at only 11 weeks of gestation. The results of the test will prove:
The presumed biological parents are indeed the genetic parents of the fetus
The absence of any surrogate genetic link to the fetus
The certified documents prepared by Viaguard facilitate birth registration and provide assurances to all parties.
Chorionic Villus Sampling (CVS)
CVS cell sampling involves taking a tiny tissue sample from the outside wall of the placenta, the sac wrapped around the fetus. The placenta is the connection between mother and baby which allows substances to pass from mother to baby and baby to mother. The fetus and the placenta both develop from the same zygote and are genetically identical.
A withdrawal of a small amount of the developing placenta can be done after 10 weeks of gestation. The Villi are finger like projections rich in fetal cells. The two techniques used in sampling are trans-cervically or trans-abdominally depending on the position of the placenta.
The procedure is usually proceeded by an ultrasound followed by CVS withdrawal and the entire process takes about 15-20 minutes with minimal discomfort. The sample of CVS cells are sent to us and paternity results are definitive and the cost of the test is $399.00.
The withdraw of a small amount of amniotic fluid from the uterus is done after 13 weeks of gestation. The patient lies down on the examination table and using ultrasound the doctor will locate a small pocket of amniotic fluid, inserts a needle, and withdraws the sample. The discomfort is usually of very short duration. The amniotic fluid sample is collected in a special kit which we supply and then returned to us for DNA analysis. Results are definitive and the cost of the test is $399.00.
While they are excellent sources of fetal DNA, CVS cells and Amniotic fluid are not used frequently in fetal DNA analysis because many doctors are not concerned with paternity issues since invasive procedures involve a small element of rick to the fetus. They tend to use these techniques primarily for taking DNA samples to test for defective genes or health related issues. This means that most women who wish to do a prenatal paternity test may readily use available non-invasive techniques.
Whose Sperm Cell - A Question of Paternity
When sperm cells are ejaculated in semen during intercourse, they are deposited close to the entrance to the uterus. A normal ejaculation (about a teaspoon) contains 200-500 million sperm cells.
As an egg is released by one of the ovaries, the normally impenetrable mucous at the opening of the uterus becomes sufficiently watery and porous for sperm penetration by about 1% of the sperm cells. During this period of female fertility, only a few hundred of these sperm cells reach the upper part of the fallopian tubes where fertilization can occur.
Sperm cells can survive in the fallopian tubes for up to seven days after coitus. This long survival period, combind with the difficulty of ascertaining the exact day of fertilization, creates problems determining paternity when there has been more than one sexual partner. Thus, pre-natal paternity testing may be advisable.
DNA in vitro and surrogate testing is now available to fertility clinics and individuals.
Prenatal DNA Testing / In Vitro Fertilization
In vitro fertilization and uterine embryo transfer are an emotional experience for all participants. A completed procedure should, after 13 weeks of gestation, include DNA genetic confirmation of the biological parents and evidence the surrogate has no genetic linkage. This documented confirmation is increasingly required by the courts, hospitals, and concerned biological parents. It may be in some cases essential to allow for a birth registration naming the genetic mother.
The documentation issued by fertility clinics, while very substantive, may not by itself be accepted as definitive evidence of the true genetic parents, and thus the need for DNA testing. The methodology used by Viaguard addresses these issues and includes the use of legal chain of custody procedures whether samples are taken at our facility or at a remote location as directed by Viaguard.
