Legal or NON-Legal DNA Tests
At times persons in need of a DNA test will look for the cheapest method or a home DNA kit, however a cheap or "do it yourself" DNA test many times are not accurate or will stand a legal challenge or can successfully defend a legal challenge in a court of law. Not all laboratory's or DNA testing centers are equal. Accredited Drug Testing only uses DNA testing Posen qualified and certified testing centers and nationally recognized DNA testing Posen laboratories.
When scheduling a DNA test regardless of the purpose, Accredited Drug Testing recommends always utilizing a legal DNA test procedure for current or future use. A legal DNA test has very specific Chain of Custody test procedures which insures that the DNA test results can be used in a legal proceeding. A non-legal DNA test will provide the results, but cannot be used in any type of legal matter. When conducting a legal DNA test all parties must present a valid form of identification, photographs will be taken of all parties, legal guardian documentation and or birth certificates of any minor children may be required. These procedures for a legal DNA test insure that should the DNA test results be used in a legal proceeding, the chain of custody is carefully followed and no challenge to the results can be successfully made, that's why it's always best to schedule a legal DNA test.
DNA testing can be used for the following purposes
- Birth Certificate Modification
- Child Support
- Child Custody
- Adoption
- Wills/Insurance
- Immigration
DNA Paternity Testing Posen
A DNA test for paternity purposes determines the biological father of a child. Every human inherits specific DNA from both biological parents, half from the mother and half from the father. A DNA test examines a child's DNA pattern with that of a alleged father to determine if the child and the alleged father have the same DNA. Results of a properly administered DNA test utilizing a AABB accredited laboratory are 99.9% accurate. While DNA paternity testing maybe stressful for some parties involved, Accredited Drug Testing is committed to making the entire DNA paternity testing experience, professional, convenient, confidential and Stress Free.
Establishing a biological relationship is important and has many benefits including
- Medical history for the child
- Establishing legal, custodial and inheritance claims
- Enhances the family unit and bond between father and other family members
When administering a DNA test to a child/minor, the legal guardian must be present and provide authorization for the DNA test to be conducted. The legal guardian can be the mother, father or other natural or court ordered person who has legal decision making authority over the minor child.
DNA Immigration Testing
DNA testing can be used for reasons relating to immigration and the biological relationship between a petitioner and affiliated individual. DNA immigration testing can be used for paternity tests, maternity tests, sibling relationship and other purposes required by the U.S Department of State. Accredited Drug Testing will coordinate the entire process, including scheduling the DNA test for parties located in the United States and forward the DNA collection kit to the U.S Embassy located in a foreign country where the other party is located. Once the DNA collection has occurred at one of our testing centers in the U.S and at the U.S Embassy where the other parties are located, Accredited Drug Testing will ensure that all specimens are sent to the lab for DNA testing and provide the results once the AABB laboratory has analyzed the DNA test.
What is a DNA test?
A DNA test is a procedure to determine if exact biological characteristics exist in one person's DNA and those exact same DNA characteristics in another person's DNA makeup. As humans each of us have different DNA makeup, however parents and children have the same DNA, siblings from the same parents have the same DNA and grandparents have the same DNA as grandchildren. A DNA test is a non-intrusive procedure usually utilizing a oral swab from all parties, which then follows a specific chain of custody process in which the oral swab specimens are sent to a certified and accredited AABB laboratory. The Laboratory than analyzes the DNA specimen and provides the results. DNA test results are 99.9% accurate.

AI Overview
Overview of DNA Testing
DNA testing is a sophisticated scientific method used to analyze genetic material from an individual to discover genetic information that can influence health, ancestry, and personal characteristics. It has revolutionized fields such as medicine, forensics, and genealogy by providing deep insights into genetic backgrounds and health predispositions.
Common Types of DNA Testing
- Medical Genetic Testing: Identifies changes in chromosomes, genes, or proteins to confirm or rule out a suspected genetic condition or help determine a person's chance of developing or passing on a genetic disorder.
- Ancestral DNA Testing: Analyzes DNA to provide insights into one’s ethnic background and ancestral origins, often revealing geographical and migratory histories of ancestors.
- Forensic DNA Testing: Focuses on identifying individuals based on their unique genetic makeup for criminal investigations or legal matters such as paternity tests.
Benefits of DNA Testing
DNA testing offers a range of benefits:
- Enhanced Medical Understanding: Helps in understanding genetic diseases and can lead to more effective treatment and prevention strategies.
- Personal Ancestry Insights: Provides a deeper understanding of one's roots and personal history related to ethnic groups and migration patterns.
- Assistance in Forensic Investigations: Essential in solving crimes, identifying perpetrators or victims, and resolving civil disputes.
Challenges and Considerations in DNA Testing
While DNA testing provides valuable insights, it comes with challenges:
- Ethical Issues: Genetic testing raises ethical questions, particularly concerning privacy, consent, and the right to not know genetic information.
- Accuracy and Interpretation: Results can sometimes be inconclusive or misinterpreted, requiring careful consideration and potentially further testing.
- Psychological Impact: Discovering genetic information can be distressing and have significant emotional impacts on individuals and families.
Choosing the Right DNA Test
When considering a DNA test, it is important to:
- Select the Appropriate Test: Choose a test that suits your specific needs, whether for health, ancestry, or legal purposes.
- Consider Privacy Policies: Understand how your genetic information will be used, stored, and shared.
- Seek Professional Guidance: Consult healthcare professionals or genetic counselors to help interpret results accurately and responsibly.
In conclusion, DNA testing offers profound insights but requires careful consideration of ethical issues, potential emotional impacts, and the challenges of dealing with complex genetic information. With the right approach and professional support, it can provide invaluable benefits.

Local Area Info: Posen, Illinois
Posen is a village in Cook County, Illinois, United States. Posen is the German-language name for the western Polish city of Pozna?. The population of the village was 5,987 at the 2010 census, up from 4,730 in 2000.
The area that is now Posen was settled by farmers, mainly of Dutch and German origin, in the second half of the 19th century. In 1893 a Chicago-based real estate firm hired 75 agents in the Polish-speaking areas of Germany to sell land to Poles seeking to emigrate to the United States. Over the next few years the village emerged as a place largely inhabited by factory workers, mainly employed at nearby Harvey, who also had room on their lots for gardens. In 1894 the Roman Catholic Archdiocese of Chicago established a mission to serve the Polish residents of Posen, which was elevated to parish status as St. Stanislaus the Martyr in 1898.
In the 1930s the population of Posen was 98% of Polish origin, and in 1960 only 0.1% of the population was identified in the census as being not white, or 4 of the 4,513 inhabitants.In 1963 there were 7% black students that attended the Posen School. In 1990 Posen, having fallen to 4,226 inhabitants, was still 94.5% white, a large portion of this population being Polish. About 4% of the population identified as being both white and Hispanic, for an overall 7.3% or 310 people identifying as being Hispanic. In 2010 3,171 residents of Posen identified as Hispanic, representing the expansion of the Hispanic population to 10 times what it had been 20 years before (or an increase of more than 900% over 10 years). In the same time period the number of African American residents of the village increased from 60 (or 1.4% of the population) to 1,035. This means that the percentage rate of growth of the African American population of Posen over the last 20 years has been greater than that of the Hispanic population. While as late as 2004 the Encyclopedia of Chicago still referred to Posen as "predominantly Polish American" even then an actual examination of the 2000 census ancestry report would have shown that only a quarter of the population claimed to have Polish ancestry.
