Our Pledge

A DNA test is lifelong. The information that you find out from your DNA test stays with you for life, and can drastically affect the rest of your life. Our laboratory proudly accepts the responsibility of performing this important test for you with confidence, professionalism, and care. Our laboratory specializes in DNA testing and will be able to help you obtain conclusive and reliable answers.

Listed below is the Code of Ethics for our laboratory. Our laboratory takes tremendous pride in the quality and care put into every test. We are proud to list our laboratory’s responsibilities and obligations to you, our patients.

Our laboratory code of ethics is intended to ensure appropriate and proper conduct. It sets forth the principles and standards of the laboratory and is intended to be used as a guide for all of our laboratory personnel in their activities and conduct.

Guiding Principles Underlying Our Code of Ethics

1. Our responsibility to our patients and clients

Above all else, we believe that our first responsibility is to our patients and clients, to the families who rely upon us for our testing services. In meeting the needs of our clients, we must do everything in our capacity to provide our clients with the highest quality testing service using only the latest and most accurate DNA technology. Because testing accuracy, speed, pricing and reliability are strongly dictated by technology in the modern DNA laboratory, we must strive to always be on top of the latest testing technology, to be equipped with the newest and most advanced testing equipment, and to only provide the latest and most accurate service available to modern DNA technology. We must constantly strive to maintain reasonable prices. Accuracy is of utmost importance and we must not under any circumstances sacrifice accuracy. In the event that extra testing is required to reconfirm data for special cases, accuracy must never be sacrificed for speed or expense. Each individual case must be serviced promptly and accurately. We must maintain the privacy of our patients and we must never use patient samples and files for any purpose other than what it was originally intended.

2. Our responsibility to our employees

We must be fully responsible to our employees: to our technical staff, our laboratory staff, and office staff who work with us within our facility as well as to our hundreds of contract personnel and registered nurses who work off-site throughout the country. All of our staff must be respected as individuals and recognized for their merit. We must ensure that we always provide an equal opportunity for employment and development. The actions of our management team must be fair and ethical.

3. Our responsibility to our community

We must be responsible to our community in which we live and work. Our laboratory must strive to support charities and bear our fair share of taxes. We must encourage improvements in testing technology to ensure better, faster, and more affordable services. Our laboratory must ensure that we are mindful in the protection of our environment in our everyday conduct through proper recycling procedures.

A. The Laboratory Personnel

  • Laboratory personnel should perform their professional duties in a manner consistent with current standards of good practice as outlined in the Quality Manual and Policy and Procedures Manual.
  • Laboratory personnel should strive to increase their knowledge and skill in order to provide the patient with a high level of professional service by keeping up to date with current developments in DNA testing technology, regularly attending relevant conferences, and keeping in touch with other experts in the field of DNA technology and DNA statistics.
  • Laboratory personnel must adhere to currently accepted methods and practices in the DNA lab in accordance to the testing protocols and procedures manual.
  • Laboratory directors must have doctoral degrees in molecular biology.
  • In general, the test results should only be provided upon completion of testing.
  • Although the majority of tests are completed in the required time frame, from time to time, special situations may arise during testing which require extra testing time. In the event that delays are encountered during testing due to lack of DNA on swab samples, or naturally occurring mutations in the patient’s genome, it may be necessary to conduct additional testing. Under such circumstances, extra time must be allowed to properly complete all necessary additional tests to generate conclusive results.

B. The Testing Facility

  • The testing facility must keep up to date with current technology.
  • As DNA testing technology is rapidly advancing with newer, faster, and more accurate and more automated technology available each year, it is the responsibility of the laboratory to have the funds available to be equipped with only the latest technology as they become available to ensure that the fastest, most affordable and more accurate testing is provided at all times.
  • The laboratory must have policy manuals for users of the laboratory as well as policy manuals governing work within the laboratory.

C. The Client

  • The client must be treated with dignity and respect.
  • The laboratory must safeguard the dignity and privacy of patients.
  • The laboratory should carry out their professional acts for the client once undertaken, to their conclusion.
  • The laboratory should preserve patient information in professional confidence.
  • A single test may often involve several individuals or family members. In performing the test, the laboratory may require personal information which is specific to the individual (e.g. contact information). The laboratory must ensure that other than the information intended in the final report, personal information regarding each individual that is not relevant to the purpose of the test must not be inappropriately disclosed to other parties involved in the test without specific written consent of the individual.
  • The laboratory should issue their reports only to the individuals who were pre-authorized to receive such information.

Y-DNA STR Marker Testing
Track the Steps of Your Y-DNA STR Marker Test

Track the steps of your Y-DNA STR marker test, step-by-step, through the various stages of DNA extraction, processing, sequencing and analysis.

Step 5: Sequencing

Sequencing is the final stage of the testing procedure and allows the scientist to visualize the Y-DNA STR markers. During sequencing, the amplified DNA is drawn up a capillary which contains a gel matrix. Depending on the type of marker, it will migrate across the gel at a different rate, effectively separating into “bands”. As bands of labelled DNA move across the capillary, they are detected by a laser beam which collects information about the Y-DNA STR marker type.

Y-DNA 20, 44, 67, 91 or 101 STR Marker Test for paternal ancestry

To follow is an example of a Y-DNA STR marker called DYS19. The section of DNA which repeats itself is TAGA. Thus, someone with a DYS19 marker of 6 will have TAGA repeated 6 times. The DNA test will indicate that the DYS19 marker is 6 for this individual. DYS19 = 6.

Someone with a DYS19 marker of 4 will have TAGA is repeated 4 times. In this case, the DNA test will indicate that the DYS19 marker is 4 for this individual. DYS19 = 4.

When a Y-Chromosome test is performed, 20, 67 or 101 Y-DNA STR markers are analyzed to generate a unique “profile” for that individual. Two males with the same male lineage with the same forefathers will have the same or similar profiles. The closer the match in profiles, the more recently two individuals shared the same forefather. Obviously, the more markers that are tested, the more powerful your test becomes and the more stringent your searches are when searching for matches.

With the exception of the egg and sperm cell, all of the cells in our body contain 23 pairs of chromosomes, 46 in total. One chromosome from the pair is inherited from our mother and the other one is passed down from our father. This is a picture of all of the chromosomes in a cell (this type of picture is called a karyotype).

Most of the cells in our bodies (with the exception of red blood cells) have a nucleus. The nucleus of all of our cells, doesn’t matter which cell type, contains chromosomes, and chromosomes are responsible for storing our hereditary information. Chromosomes are made up of DNA (stands for deoxyribonucleic acid). DNA is like a blueprint because it holds the informational code for all of the genetic information for that person. The DNA for each individual is unique to that person.

If we were to hypothetically untwist the DNA strand and lay it flat, it would look like a ladder. The two sides of the ladder are called the DNA’s “backbone”. The steps inside the ladder represent “bases”. There are 4 types of bases in DNA: A (for adenine), C (for cytosine), T (for thymine), and G (for guanosine). In the DNA strand, A always pairs with a T, and C always pairs with a G. The unique sequence of the A, C, T, and G in DNA forms codes which carry genetic information.

When DNA is deciphered by genetic testing, the DNA code can be written in the following manner:

A G C T G G G A C A A T G G G C G C T A G G C C C C C C…

No two individuals (except for identical twins) have exactly the same genetic code and that is what makes everyone unique. However, all males with the same surname who are originated from a common paternal lineage will share the same or very similar genetic code in their Y-Chromosome. Unrelated males from a different family line will have a different Y-Chromosome code.

A male inherits his Y-Chromosome directly from his father. The Y-Chromosome that a male receives from his father is very special because it holds a lot of valuable information about his ancestry. This is because the Y-Chromosome is passed down along the male line, relatively unchanged from generation to generation. A forefather will pass his Y-Chromosome down to all of his sons, and they will then pass it down to all of their sons, and so on throughout the generations along the male line. Thus, males who are descendents of the same line will have the same or nearly identical Y-Chromosomes.

When a Y-Chromosome genealogy test is performed, the laboratory examines specific regions (markers) along the Y-Chromosome called “hypervariable” regions. Hypervariable regions are areas within the Y-Chromosome that may differ greatly between different family lines. The type of hypervariable region which is studied in Y-Chromosome testing is called STR markers (stands for “Short Tandem Repeat” markers). STR markers are regions of the Y-Chromosome where small chunks of the DNA are repeated over and over again. The number of times that these small chunks of DNA repeat themselves in the Y-Chromosome is variable amongst different family lines.

By testing your Y-DNA STR markers, a DNA laboratory can provide you with your Y DNA STR marker profile which is specific for your paternal ancestry. Because all males with the same ancestors will have the same or similar Y DNA STR marker profile, you can compare your markers against other males to solve questions about your paternal ancestry, to conclusively link family lines and to discover you distant relatives who share a common paternal ancestor with yourself. DNA testing has become the most exciting and fastest growing branch of genealogy.

Step 4: PCR Amplification

PCR stands for “Polymerase Chain Reaction”. During the PCR process, the DNA strands are separated at high temperatures. “Primers” are added to the reaction. These primers are specific for each Y-DNA STR marker which is examined. The primers are designed to anneal “stick” to the DNA strands. After the primers have annealed around the part of the DNA to be examined, the conditions are changed and the region of interest is duplicated using a chemical called TAQ polymerase.

This process is repeated over and over again to specifically amplify the Y-DNA markers of interest. In just hours, this PCR process will generate millions of copies of the marker of interest for examination.

Step 6: Analysis

The information obtained from Step 5 is then output into a computer which displays the results as a series of peaks. Each peak corresponds to one Y-DNA STR marker and the location of the peak allows the lab to determine the size of the Y-DNA STR marker. This raw laboratory data is then converted into allele values which are used to generate a final report indicating your exact Y-DNA STR marker profile.

After testing many STR markers on your Y-Chromosome, you will obtain your Y-DNA STR marker profile. This is also called your “Y-DNA haplotype”. Your Y-DNA haplotype is the overall profile for your DNA markers and is unique to different family groups.

By comparing your Y-DNA haploytype to other males, you can begin piecing together the puzzle of your global family network. Because your Y-DNA haploytpe is passed down to you from your ancient forefathers, all males who share the same lineage as you, even if it is very distant, will have the same Y-DNA haplotype as you. Using this powerful information, you can determine whether a family line with your same surname shares a common paternal ancestor with you (same paternal family line as yourself), and which family groups originated from a different paternal line.

To follow is a scenario of how Y-DNA STR marker testing can help Mr. Brown dig up his ancestral roots:

Mr. Brown is interested in researching his roots and is expanding his ancestral search. Mr. Brown has several male relatives which share his surname. The oldest living male member of his Brown line is his grand-uncle who is 89 years old.

Mr. Brown begins by testing himself, his male cousin (his dad’s brother’s son), and his grand-uncle. Because of the age of his grand-uncle, it is important for him to test the senior Mr. Brown right away because his grand-uncle is physically very frail and may not be available for testing in a few years.

After conducting the test, as expected, Mr. Brown verifies that all three have exactly the same Y-DNA STR marker profile. After speaking with his grand-uncle, he was able to trace distant relatives in Europe who share his surname. After contacting various members of his European line, he obtained 9 participants and the results of the test show the following:

Mr. Brown and his cousin share the same Y-DNA STR marker profile. He also shares the same Y-DNA STR marker profile as group 2 and group 5 of his European line. There is a single mutation in group 3 and group 4, indicating that although they are related, it is more distant, and that groups 3 and 4 are closely related to each other. Group 7, however is not related to this particular Brown family line.

After finding out this exciting information, his newfound European family lines were able to bring more extended family into the surname project, and within a few months, Mr. Brown was able to connect and piece together a large puzzle of his ancestry.

Mr. Brown then searched the DNA Reunion public database for genetic matches and found that several other lines of Browns in Australia and Germany matched his Brown line perfectly, thus allowing the three Brown families to merge their information into a large global project. In a matter of 6 months, Mr. Brown has pieced together his ancestry dating back to the 1300’s and is now in contact with his “global family”, a family of Browns who are descendents of a common Brown ancestor.

Mr. Brown is now continuing to grow his highly successful project by encouraging other Browns worldwide to participate to see if they are linked. The Brown project has become very interesting with a deep history and many remarkable figures and ties throughout history. Mr. Brown feels that his journey has opened an amazing chapter of his life and is now en route to linking together Brown lines worldwide and discovering and recreating his amazing lineage.

Step 1: DNA Collection

DNA is collected from inside the mouth using special swabs provided in the Participation Kit. By rubbing the swabs gently inside the mouth against the cheek, loose skin cells called “buccal cells” will adhere to the swab. Buccal cells contain DNA which is used for DNA ancestry testing.

The collection is fast and painless, and takes seconds to complete. After collection, the samples are inserted into the pre-addressed return envelope provided in the kit and sent directly back to the laboratory for processing.
