Native American DNA Test

The American Government offers new economic benefits to people of Native American origin. In the light is this bonanza, the Native American DNA test is a vital pathway to establish and legitimize claims of Native American ancestry. The Native American DNA test unlocks the mystery surrounding the Native American society’s ancestral roots and of how they came to be in America. Scientists discovered the importance of DNA pertaining to evolution. It is believed that the Native American DNA test can have a positive impact on the Native American Community.

The Native American Testing Services

The largest and most experienced private Native American DNA test services in the US, the DNA Diagnostics Center aims at making the technology available at affordable cost. A trained professional collects the samples using a painless cheek swab procedure. Usually the testing services have nationwide network of sample collection centers. Consultation and complimentary training for collection of samples also are provided by some testing services.

GeneTree’s Native American DNA Testing Kit

Using the GeneTree’s Native American DNA Test kit, your roots to the Native American tribe can be established. It can also determine the mix of origins. Even the percentage of such mixture of origins is measured using this test.


Genelex conducts this test and offers three options as described below:

Ethnicity DNA Testing

This test determines the ancestry by the DNA 2.5 known as DNA Identity Profile. It gives an estimated percentage of origins such as Native American, Asian ancestry Indo-European or African along with a unique genetic fingerprint.

Maternal Line Native American Test

This Native American DNA test known as the mtDNA for males or females traces the ancestry through the maternal line. The DNA passed from the individual’s mother and mother’s mother is examined for genetic markers that indicate Native American origin.

Paternal Line Native American Test

The Y Chromosomes indicate paternal link as they are passed to the son by the father. The test reveals the paternity and through this the ancestral origin. This test reveal any roots to their population. DNA from the individual’s father and father’s father etc are examined for unique link to Native American heritage.

Scientific advancement has helped in the process of determining the ancestry through DNA test. The Native American DNA Test can have a positive impact on the Native American society.

Low Cost DNA Testing

The discovery of rapid, low cost DNA testing by Professor Lewis Rothberg of the University of Rochester and his group, won him a NYSTAR grant for further research. Rothberg’s innovative new procedure identifies genetic sequences in a DNA sample inexpensively and quickly.

Uses of this low cost testing

This low cost DNA testing can help in improving our health in general and make sure that the drinking water is clean and the food is uncontaminated. This revolutionary method can be used by forensic labs to identify criminals, identify harmful genetic sequences in clinical research and even test the swimming pools for its suitability for allowing children to swim in them. This new method is effective, fast and simple while the cost is very low.

The Technology

This low cost DNA test uses a technology that is a novel fluorescent screening assay that determines if specific DNA target sequences are present in the analyzed sample. If the target sequences and other sequences are present the assay filters out only the target sequence. Rothberg’s assay is done on the basis of the electrostatic properties of DNA.

Low cost

The most commonly used common test is gel electrophoresis. Each test costs around USD 1.00 and takes one hour. The capital expenditure for setting up a lab is around USD5000. On the contrary, Professor Rothberg’s technique requires just 5 minutes and it costs USD0.05 (5 cents) per test. The lab setting up cost is only USD600.

The procedure

The first step is Hybridization that takes 10 seconds and costs USD0.025. The second step is to add gold colloid to the hybridization solution taking 10 seconds and costing USD0.02. The third step is to add salt to the solution taking another 10 seconds and costing USD0.01. The last and fourth step is to measure photoluminescence in one minute.

This new method is part of a three-step process of extracting, magnifying and then testing the DNA from the blood, tissue or food. This process saves the final hour of work for the technician thereby saving time as well as cost. More important than saving time and money, this method helps to determine the single-base mutations in that will be linked to a prescribed therapy.

Professor Rothburg of Rochester University discovered a low cost DNA testing method. This method saves time and money and helps in improving health and detecting criminals and food and water contamination.

Legal DNA Testing

Legal DNA Testing is testing process that can help families resolve all relationship questions. The tests usually performed are paternity test, maternity test, kinship test, aunt/uncle/nephew/niece test, grand parentage test, ancestry test and forensic test. The 23 pairs of chromosomes all people have inherited half of them from our mother and the other half from our father. When a child’s DNA profile is compared to its alleged father’s profile, if the result shows exclusion, the alleged father is not the biological father of the child. If it says “inclusion” it means that the alleged father is also the true biological father.


Conclusive answers to paternity issues are possible with Securigene paternity tests. Securigene is one of the world’s few Legal DNA testing labs that have accreditation from both AABB and ISO 17025 and their results are recognized across the globe. Their testing is flawless as they have done thousands of tests and maintained a100% court recognition. The tests are carried out twice to ensure 100 percent accuracy. Legal DNA testing Labs usually test only 9 to 12 loci and the 16 loci are test is run only for very few special cases. At Securigene, a guaranteed run of the 16 loci is routinely performed in all cases. Securigene has collection sites all over North America and worldwide. The Legal DNA Testing analysis takes 3 to 5 days and the legal and certified reports are sent immediately. Consultation is free and is available on phone or email.

Atlanta DNA Center, Inc.

Having networked all over the country, Atlanta DNA Center, Inc. will locate the nearest collection facility to your place and schedule an appointment on the day and time that that suits you. They work with the nation’s # 1 lab and the legal testing lab and obtained the highest accreditations.

Collection procedure

They collect one form of identification of the each person and also take his photograph and thumb print. The painless process takes just minutes and the samples are collected from each person. The necessary paperwork is completed in the client’s presence and the collected material is sent to the lab for testing.

Legal DNA testing is accepted in courts if done in the appropriate accredited labs. The testing is done to resolve issues of paternity and other blood relationships by establishing the DNA match.
