Gotta Know Testing takes DNA samples from each person to create individual genetic profiles

Gotta Know Testing obtains DNA samples from buccal (cheek) swabs for testing and analysis. Buccal swabs are like cotton swabs, but we use a special Dacron® polymer instead of cotton to provide a consistent surface for DNA collection. When the samples reach our laboratory(DDC), the staff checks each sample package as it arrives, checking for signs of tampering. If the package is intact, it then undergoes our proprietary Dual Process™ DNA testing procedure. Two independent teams do the following:

  1. Review accompanying documents to make sure all forms are properly filled out.
  2. Assign the case number and create a record for the sample.
  3. Take half of the buccal swab samples and purify DNA from the swabs. DNA purification and isolation is performed using our Biomek® robotics systems.
  4. Perform the polymerase chain reaction (PCR) to make billions of copies of the DNA markers.
  5. Analyze the PCR products using the ABI Prism® 3100 genetic analyzer. These detect the marker sizes in each sample, generating the raw data.

The staff carefully tracks the samples and verifies completion of each step throughout the Dual Process™. The raw data from the two teams are reviewed by the laboratory director. If the data shows no anomalies, statistical calculations are performed on the genetic profiles of each tested party.

Facts about DNA Testing 
As many as 1 in 10 men have doubt about fatherhood. Testing for paternity as early as possible will help bring Peace of Mind sooner, and save a child from future confusion and anxiety. We provide the answers to paternity quickly, painlessly, and compassionately. Paternity Testing simply means establishing fatherhood. Everyone is born with a unique genetic blueprint known as DNA (Deoxyribo Nucleic Acid). DNA is passed down from mother and father to a child. DNA Identification provides a conclusive way to determine biological relationships. Consequently, DNA Testing has become the most accepted method to determine identity within the legal and scientific communities. We use a painless, non-invasive mouth swab (buccal swab) for collection instead of drawing blood (unless requested by the customer). The result from using the buccal swab are just as accurate as results obtained from a blood draw. Results are delivered in an average of 3 days. First thing you must decide is if you need a Court Admissable Paternity Test or a Personal PaternityTest (Peace of Mind). We are able to coordinate testing in any city, state or country. We have an exclusive relationship with DDC Lab (DNA Diagnostics) which allow us to offer you excellent and affordable service. The cost of court admissable (AABB) paternity test is $345.00. If you do not require court admissable test results, Gotta Know Testing now offers Peace of Mind Testing for only $245.00. Same day appointments are available. For your convenience we are open on Saturdays by appointment only.
