Advantages of fetal DNA analysis in the maternal blood

1. Analysis of fetal DNA and fetal cells in maternal blood samples is a screening test that is a non-invasive prenatal procedure and poses no risks to the mother or the fetus. The non-invasive prenatal DNA paternity testing is based on the comparison of genetic profiles of the fetal DNA, mother's blood and samples from the alleged fathers.

Timing for the test

Using DNA test from Prenatal Genetic Center, prenatal DNA paternity can be performed after the 14th weeks of gestation.


The procedure takes only 7 business days, and the report contains one of the following results:

- The Alleged Father cannot be excluded as the biological father of the fetus based on the samples submitted from the mother and the alleged father and the DNA extracted from the population of fetal cells;

- The Alleged Father is excluded as the biological father of the fetus based on the samples submitted from the mother and the alleged father and the DNA extracted from the population of fetal cells.

Sensitivity and specificity of the test

Sensitivity and specificity of the detection of cell-free fetal DNA at 14 weeks of gestation for properly collected maternal blood samples is more than 99%. We strongly recommend testing all alleged fathers that are involved in your case (no extra charge for an additional alleged father).

Price for the prenatal DNA paternity test

Total price of laboratory DNA testing for the prenatal paternity test on blood is only $990.00 (US). The cost includes a sample collection kit, the diagnostic laboratory tests for the mother and all alleged fathers, the laboratory reports a) for fetal DNA testing as well as b) free follow-up testing for a newborn child. Please make sure that the payment for the non-invasive prenatal paternity test is included in the form of money order, VISA, Master Card or American Express. A non-refundable deposit of $200.00 is required to initiate the scheduling process and will be applied towards the case. The balance must be paid in full before we can release the DNA test results. All prices are in US dollars.

Benefits of doing non-invasive prenatal paternity testing with our laboratory

       Our laboratory is offering a full package for the our  clients:

bold">a.     Free pretesting consultation for your case: explanation about prenatal testing; types of sample that can be collected from the alleged father(s) such as swab, hair, toothbrush and other samples; the best place and time to collect a blood sample from the mother; sending a sample collection kits to two different places (one for the mother and second for the alleged father) etc.

bold">b.      No extra charge for an additional alleged father(s). We will test all alleged fathers that are involved in your case.

bold">c.    Double DNA testing for the same child: the first test on fetal DNA extracted from maternal blood samples and the second test is a free follow-uptest for a newborn child. Double DNA testing can give a double assurance to our clients: no uncertainties about the paternity of your child.

Full confidentiality of our testing: the mother can submit different samples from the alleged father(s) without asking him about. Our laboratory is accepting hair samples, toothbrushes, semen stain and other forensic samples collected from the alleged father.

Based on 11 years of our experience in non-invasive prenatal testing, our laboratory is offering more cost-effective (only $990 for a full package), less time consuming (only 7 days for the test result) and simple to carry out (blood sample collection close to your place) prenatal paternity test.

Non-Invasive Prenatal DNA Gender test on Maternal Blood

The current standard care offers an invasive prenatal gender test only to those women whose risk of chromosomal or genetic abnormalities are greater than or equal to the risk of a procedure-related loss. Given the relatively easy identification of male DNA in maternal blood, one clinical application is the non-invasive identification of male fetuses at risk for X-linked disorders.
