Accredited Drug Testing takes the stress, out of a stressful situation!
Important Information (Beware)
Some companies offering DNA Testing may sell cheap / INEXPENSIVE, in-home or laboratory DNA kits. Please be aware that these types of DNA testing products cannot be used in a court proceeding FOR paternity, immigration or family relationship determinations.
Accredited Drug Testing only utilizes certified DNA collection specialists at our San Lorenzo, CA DNA Testing Centers and AABB certified laboratories for DNA Testing which the test results may be utilized in child custody, child support, paternity or any other legal proceeding.
Accredited Drug Testing provides DNA testing in all cities nationwide and in the event the parties for the DNA test are located in different cities, Accredited Drug Testing will coordinate and schedule all of the DNA tests to ensure that all parties are accommodated in a convenient manner. As an example, if the mother and child are in one city, but the alleged father is in another, we will contact all parties to schedule the DNA test at a convenient location and time and report the results back to the authorized parties.
Legal or NON-Legal DNA Tests
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 ensures 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 ensure 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.
Accredited Drug Testing Recognized For DNA Expertise
Recently, Accredited Drug Testing and our company President and CEO, James A. Greer was consulted by the National Enquirer magazine regarding the JonBenet Ramsey murder case. Mr.Greer's comments were included in both the September 12th, 2016 edition and the January 2nd, 2017 edition of the National Enquirer.
Please note - Accredited Drug Testing, Inc. only utilizes American Association of Blood Bank (AABB) certified laboratories for DNA relationship testing. The AABB accreditation is the highest national standard applied to DNA testing laboratories.
Any DNA test which is conducted by a non- AABB laboratory will not be accepted in a court of law. Home kits and other types of non- AABB DNA testing, while inexpensive/cheap, are not reliable and will not be permitted in a legal proceeding.
Accredited Drug Testing Inc, applies the highest standard to the entire DNA testing process, from the DNA specimen collection, to the chain of custody, the laboratory analysis and the confidential results reporting.
To schedule a DNA Test or for more information including fees, Please call (800) 221-4291

DNA Paternity Testing
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 an alleged father to determine if the child and the alleged father have the same DNA. Results of a properly administered DNA test utilizing an AABB accredited laboratory are 99.9% accurate. While DNA paternity testing may be stressful for some parties involved, Accredited Drug Testing is committed to making the entire DNA paternity testing experience, professional, convenient, confidential and Stress-Free.
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 contains 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 an 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 that analyzes the DNA specimen and provides the results. DNA test results are 99.9% accurate.

More DNA Testing FAQ
What is paternity?
Paternity means fatherhood. Paternity is established when a paternity testing laboratory uses genetic testing methods / DNA test, to demonstrate to a legal standard, that an alleged father is the biological father. Paternity is disproved when these same methods and standards demonstrate that an alleged father is not the biological father.
What is DNA testing?
DNA testing refers to the process of examining an individual's DNA markers for the purpose of genetic human identification and for determining the relationship between two people.
How accurate is DNA-Based paternity testing?
The DNA profiling method is an extremely accurate genetic testing method. It can absolutely determine if the man is not the biological father and reliably exclude him. DNA profiling can establish that the alleged father is the child's biological father with a probability of paternity of 99.99% or higher. Each year many individual clients, child support offices, attorneys, judges, and physicians choose Genetic Profiles as their source for information, guidance and testing services in order to determine paternity.
Are the results admissible in court?
Yes. The laboratory follows a strict chain-of-custody procedure which allows for court/legal admissibility.
Is the Lab accredited? Are the results reliable?
The DNA testing laboratory used by Genetic Profiles is accredited by the American Association of Blood Banks(AABB)for the purpose of performing paternity (parentage) tests. Your paternity test will be processed by highly skilled and trained laboratory technicians. Every test is evaluated by a Ph.D. scientist with several years specializing in DNA genetic testing.
How long does it take to receive results from the paternity test?
It typically takes about 3-4 working days to complete the testing. In cases where the mother's sample is not included or when an abnormal/difficult sample is used, testing may require more time.
Are the paternity test results confidential?
Yes, The DNA test results are strictly confidential. They are released only to the adult persons who were tested and, as requested, to their authorized agents (e.g. attorneys).
How does DNA paternity testing work?
DNA analysis, which has proven to be a major advance in the field of paternity testing, involves the direct examination of the genetic material that a child inherited from its biological parents. DNA is located throughout the human body and in the same identical form. Thus, DNA in blood is the same as that in skin, cheek lining, muscle, bone, teeth and various other tissues. The DNA of a person is fully established at conception and remains totally constant throughout life. During the paternity testing process, the genetic characteristics of the child are first compared to those of its mother. Those characteristics in the child that cannot be found in the mother have been inherited from the biological father. If the tested man (alleged father) does not have the genetic characteristics necessary to be the biological father of the child, he is excluded. If the tested man's DNA does contain those genetic characteristics, then the probability that this man is the true biological father is calculated and reported by the laboratory.
What are some of the reasons DNA testing is conducted?
There are many legal and personal reasons that require DNA testing. Some of the more common include:
- peace of mind
- family medical concerns
- child support
- custody
- adoption
- citizenship/immigration
- inheritance/benefits (social security, insurance, etc.)
- crime scene analysis (forensic testing)
Can I do anything to alter the results of the test?
No, you can not alter the results of a test. Medication, drugs, alcohol, food, age or lifestyle cannot alter the DNA pattern within an individual.

AI Overview
DNA Testing
DNA testing, also known as genetic testing, involves examining an individual's DNA to identify genetic differences or mutations that may be indicative of certain conditions or diseases. It is a powerful tool used in a variety of contexts, from medical diagnostics and forensic analysis to genealogy and ancestry exploration.
Types of DNA Tests
- Diagnostic Testing: Used to confirm or rule out a specific genetic disorder. It is often conducted when a particular condition is suspected based on physical symptoms.
- Carrier Testing: This type of test is useful for individuals who may carry a gene for a genetic disorder. It is particularly important for couples considering starting a family.
- Prenatal Testing: Performed during pregnancy to assess the health of a fetus. It can detect conditions like Down syndrome, cystic fibrosis, or other genetic disorders.
- Forensic Testing: Used in legal contexts to identify individuals in criminal cases or to settle disputes in paternity cases.
- Ancestry Testing: Provides insights into one's ethnic background and genealogical roots. This test can help individuals understand their family history and origins.
Applications of DNA Testing
- Medical Diagnosis: Helps in diagnosing genetic diseases and conditions, allowing for targeted treatment plans.
- Paternity and Family Relationship Analysis: Determines biological relationships between individuals, often used in custody cases and inheritance claims.
- Personalized Medicine: Assists in selecting the most effective therapies based on an individual’s genetic profile.
- Crime Solving: Aids law enforcement in identifying suspects or victims using genetic evidence.
Advantages of DNA Testing
DNA testing provides several benefits:
- Accurate Diagnosis: Enhances the accuracy of medical diagnoses and the efficacy of treatment strategies.
- Early Detection: Facilitates the early detection of predispositions to diseases, potentially leading to preventative measures or early interventions.
- Family Planning: Offers critical information for prospective parents concerning genetic disorders that could be passed on to offspring.
Limitations and Ethical Considerations
Despite its many applications, DNA testing raises important ethical and privacy concerns:
- Privacy Concerns: Handling and protection of genetic data is critical as it contains sensitive information about an individual’s health and predisposition to diseases.
- Potential for Discrimination: There is a risk of genetic discrimination by employers or insurers based on an individual’s genetic information.
- Emotional Impact: The results from DNA testing can have significant emotional implications for individuals and families, particularly when revealing unexpected or distressing information.
In conclusion, while DNA testing offers profound insights into genetics and has transformative potential across various fields, it must be approached with caution, respecting ethical standards and privacy laws to safeguard individuals’ rights and well-being.

Local Area Info: San Lorenzo, California
San Lorenzo, also known as San Lorenzo Village, is a census-designated place (CDP) located in the East Bay of the San Francisco Bay Area in Alameda County, California, United States. The population was 23,452 at the 2010 census. It is an unincorporated community, located at the banks of San Lorenzo Creek. It was originally named Squattersville in 1851, but later renamed to San Lorenzo.
In 1944, under contract to the U.S. Navy, The David D. Bohannon Company began construction of San Lorenzo Village, which was one of the nation's first planned communities, with parcels designated for schools, churches, parks, and several retail centers. Bohannon's pioneering pre-cutting techniques, referred to as the "California method," were used in later developments, such as the more famous Levittown, Pennsylvania.
According to the United States Census Bureau, the CDP has a total area of 2.8 square miles (7.3 km2), of which, 2.8 square miles (7.3 km2) is land and 0.24% is water. San Lorenzo Creek runs partly through the town. It is located between the incorporated cities of San Leandro to the north and Hayward to the south.
