If you are pregnant and would like to establish paternity of the unborn child, you may want to consider a prenatal paternity test. The test could be performed after 12 weeks of gestation, depending on one of the procedures described below.

Prenatal paternity testing is designed to establish paternity of an unborn child. The testing compares DNA samples from the mother, alleged father, and unborn child to establish the parentage of the unborn child.

DNA REFERENCE LAB INC can work directly with your current physician or assist you in finding a physician in your area.

DNA REFERENCE LAB INC establishes prenatal paternity by utilizing three different methods.

Benefits of the Procedure

Early detection. There are two procedures: Amniocentesis (12–21 weeks) and CVS (12-16 weeks).

1. Amniocentesis. An OB/GYN will collect amniotic fluid containing fetal cells from the unborn child’s sac. DNA will be isolated from the amniotic fluid and compared to the mother’s and alleged father’s DNA.
2. CVS. An OB/GYN will collect chorionic villi (CVS) from the placenta. DNA will be extracted from the CVS and compared to the mother’s and alleged father’s DNA.

   Late detection. Maternal circulating fetal cells (16–22 weeks)

3. Noninvasive procedures using maternal circulating fetal cells (research use only).

The procedure is valid only in cases of a first-time pregnancy. Blood (40–50 mls) will be collected from the mother and a buccal swab from the alleged father. Fetal circulating cells will be isolated from the mother’s blood, and extracted DNA will be compared to the mother’s and alleged father’s DNA.

DNA banking involves the collection of an individual’s DNA sample and profile for storage and information purposes, which will be utilized at a later date. The military may require a soldier to be tested as part of a routine procedure. A parent may want their child to be tested if, in the future, the unthinkable may happen and DNA identification is required.

Do you want the family DNA banked? Do you just need the profiles? DNA REFERENCE LAB INC can test as many people as necessary to fit your needs at a significantly lower cost than testing each person individually.

Do you need legal documentation to establish the DNA profile? DNA REFERENCE LAB INC provides legal documentation establishing our results as valid in a United States Court or Embassy.

Here at DNA REFERENCE LAB INC, we will not cease testing until we give you the most complete result possible. We offer price matching nationwide to other AABB-accredited labs.

Our infidelity testing process involves four steps:

The first step, screening, is performed on the item(s) using a highly sensitive blue light source capable of revealing hidden stains such as semen.

The second step, presumptive testing, begins on the stains in question. A small sample of the stain is screened to determine if the stain could contain a particular biological fluid using chemical indicator.

The third step, confirmatory testing, involves more powerful chemical indicators or microscopic testing and allows a small sample of the stain to be thoroughly examined for the presence of that particular biological fluid or the presence of sperm in the case of semen screening. This test will also allow us to detect the presence of a bacterial or yeast infection that can mask itself as a potential semen stain.

The fourth step is DNA analysis. If positive for semen, blood, saliva, etc., the client may submit a sample of their own DNA for comparisons against the questioned stain to rule out the possibility of the stain belonging to them. Any personal effects or items containing DNA from individuals in question may be submitted for comparison to the questioned stain, but understand that even in a legal case, a court-ordered reference sample is required from an individual in order to legally bind them to the evidence if we can not exclude them.

• Please collect the sample using gloves, place it in a paper bag or envelope, seal the container, and bring the item into the lab.

• Photograph the evidence before handling the item. Place a ruler or a coin next to the item before photographing so there is a frame for size referencing.
• Use gloves to pick up the item. Otherwise, your DNA can easily be transferred to the item.
• Package the item in a paper bag or envelope. Plastic bags induce mold, especially in the heat.
• Seal the bag or envelope with packaging tape, signing across the tape with your initials and the date.
• Note the time, date, and location where the collection was made.
• Bring the sample to the lab and fill out our chain of custody forms for legal delivery.
