NON-INVASIVE PATERNITY TESTS: WHAT ARE THEY ABOUT?

The non-invasive prenatal paternity test is the most technologically advanced way to determine paternity during pregnancy. It involves taking a blood sample from the expecting mother and a sample from the alleged father, as fetal circulating free DNA can be obtained from the mother’s blood.

This non-invasive test is 100% safe for both the mother and the fetus, with no risk of miscarriage. To obtain the fetal sample, at least 10 ml of the mother’s peripheral blood must be collected in special tubes. Please contact us to schedule the most suitable day for the blood draw at our facilities. An appointment is required. When booking, make sure to specify that you need a Non-Invasive Prenatal Paternity Test.

For the alleged father’s sample, the following types of biological samples can be used:

• At least 2 ml of blood with EDTA anticoagulant.
• At least 5 blood spots larger than 0.3 cm² on FTA paper.
• At least 6 swabs rubbed inside the mouth. Please allow them to air dry for at least 1 hour and store them in a paper envelope rather than plastic.

In addition to paternity testing, there is also the option to determine the fetus’s sex and screen for trisomies/aneuploidies in chromosomes 21, 18, 13, X, and Y, as well as up to 93 types of microdeletion/microduplication syndromes.
