Facts about DNA/ Paternity 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 admissible (AABB) paternity test is $345.00.  If you do not require court admissible test results, Gotta Know Testing now offers Peace of Mind Testing for only $245.00.  Same day appointments are available in most cases.  For your convenience we are available by appointment on Saturdays and have mobile collectors available 7 days a week.  DNA SERVICES:  Prenatal Paternity (New Non-Invasive)  Paternity Testing          Ancestry by DNA   Examines your DNA to find out where your ancestors came from Grandparentage (One or both paternal grandparent and child required) Siblingship (Test for Full or Half Sibling Relationship) Maternity Testing (Child and Mother) Avuncular (Child & Alleged Uncle) Secret Paternity (Alleged Father or Child) Semen Detection Post-mortem/ Estate Testing (Testing or storing samples from decedent-collected at morgue, stored samples or known relatives of the decendent)
