IDNA Systems, Inc. provides DNA analysis services for Human Identification Testing.  Our services are described more fully in other sections.  Please follow the appropriate links.  Feel free to call us with your questions.

IDNA Systems offers the widest spectrum of parentage tests available including  Private Home DNA tests, Legal standard tests that meet evidentiary standards, motherless testing, prenatal paternity testing-amniocentesis testing (must be prearranged so a sample can be sent to us at the time of testing), kinship/sibling/half-sibling analysis, newborn or umbilical cord testing, grand-parentage, twins and deceased paternity testing.



DNA Paternity Tests and More

Accurate DNA testing for paternity, sibling and other relatedness studies.  We offer the best technology available at a reasonable price.  We test 16 DNA marker systems which allows for results that are statistically very accurate.

We offer 3 ways to order tests

  1. Mail-in prepaid orders.  See the Private Paternity Order Form (Mail-in) for the sample information sheet, authorization and indemnity form and a form for credit card payments, if you need it.

  2. Internet orders.  See the Internet Order Form to order prepaid Private Paternity Tests.  Simply choose the appropriate set of services needed to place them in your shopping basket, then check out.  All payments will go through PayPal so any major credit card, e-checks or PayPal account transfers can be used.  Additionally, PayPal has protections for both the buyer and seller to make the transaction secure.

  3. Telephone orders.  You may order any of our DNA tests by telephone at (888) 440-IDNA.  We recommend this especially for tests other than routine Private Paternity Tests.  Some of the other tests require special handling, witnessed sample collection (Legal tests) or determining appropriate individuals that need to be tested.  We welcome all telephone inquiries.

Call us to discuss your particular situation so we can customize our service for your needs.  All conversations are confidential and maintaining your privacy is as important to us as it is to you.  As soon as a deposit or payment is received, we will send the collection kits, complete instructions and sample information/authorization/indemnity form.

We offer the following DNA tests

  • Paternity Trio- Mother, Alleged Father and Child (most accurate > 99.999%  This is more accurate for non-exclusions than motherless tests).  This is the best test available.  This is usually used for any legal (evidentiary) test unless the mother is absolutely unavailable (for example, deceased).

  • Motherless Paternity -  Alleged Father and Child accurate for exclusion, but not for non-exclusion.  Since we test 16 markers, we can usually detect an exclusion.  If the other alleged father is related to the alleged father tested (for example, a brother), then the Paternity Trio would be required to be able to distinguish paternity with a high degree of reliability.

  • Maternity test - test for biological mother.  Mother and child tested exclusion 0%, inclusion >99.9%

  • Twin Zygosity (Identical Twins versus Fraternal Twins).  Comparison of DNA profiles

  • Heteropaternal Superfecundation (rare case of fraternal twins having different fathers). 

    • This is best performed as a paternity test including both parents plus both twins

    • inclusion (non-exclusion) >99.999%, exclusion 0%

  • Aunt/Uncle (aunt or uncle and a niece or nephew)

    • (<20% exclusion or >80% inclusion, but can range from 1%-99%)

    • because of the nature of the relationship and inherent limitations of the analysis, the results can fall into the inconclusive range >20%, but <80%.  This test is usually reliable.

  • Grand-parentage (when alleged father is unavailable; tests mother, child and father's parents)

    •  Single Grandparent DNA Analysis: This DNA test includes ONE grandparent, 1 grandchild, and parent optional, but strongly suggested.

      • The conclusive range for DNA results  probabilities >90% that indicates non-exclusion (inclusion) or <15% for exclusion

      • Results may vary between 1% and 99% accuracy

    • Standard Grandparent DNA Analysis: This DNA test includes BOTH grandparents, 1 child, and parent optional, but strongly suggested. For the most accurate results in a grand-parentage analysis it is best to include both the alleged grandparents and the child.

      • When both alleged grandparents are included the DNA results can indicate greater than 99% (for inclusions) or 0% (for exclusions) probability of the Grand-parentage relationship.  This test is usually reliable.

  • Cousins (First Cousin) (<20% exclusion or >80% inclusion, but can range from 1%-99%)

    • because of the nature of the relationship and inherent limitations of the analysis, the results can fall into the inconclusive range >20%, but <80%.  We do not consider this a very reliable test and should be used only if the relationships cannot be determined using Uncle/Aunt vs. Nephew/Niece tests.

  • Siblings (exclusions <15%; inclusions >90%).  This test is usually reliable.

  • Half-siblings (exclusions <15%; inclusions >90%)  This test is usually reliable.

  • Individual DNA profiles (16 markers) 

    • Probability of Identity:

      • African American 1 in 1.3 x 1018

      • US Caucasian 1 in 5 x 1018

      • US Hispanic 1 in 7.7 x 1018

      • Native American 1 in 3.6 x 1017

What are some of the uses for DNA tests?

  • Determine parentage (mother or father)

  • Immigration such as a Petition for Alien Relative

  • Adoption - to confirm biological parentage of child to be adopted

  • Adoptees - to confirm relatedness to biological family members that may be found such as siblings, cousins, half-siblings, parents, aunt, uncle

  • Determine whether twins are identical or fraternal

  • Determine whether fraternal twins have the same or different fathers (rare, but it does happen)

  • Divorce - child custody

  • Individual DNA profile that can be used for identification purposes

  • Infidelity Testing

Semen Detection Testing

Semen detection in stains on clothing or other objects.  Acid Phosphatase presumptive testing, and DNA profiling.
