Uniqueness of DNA

All people have 23 pairs of chromosomes, 46 in total. One half is inherited from our mother and the other half is inherited from our father. Gene make up the blueprint for our body, governing factors such as growth, development and functioning. Almost every cell in the human body contains a copy a copy of the blueprint, stored inside the nucleus. Each cell of the body contains DNA organized into 23 pairs of chromosomes. Each chromosome contains thousands of genetic makers or "gene". Of the 46 chromosomes in each cell, two determine gender while the other 44 determine other traits. Certain portions of DNA are unique to each individual. This genetic information cannot be purposely altered in any way. DNA profiling is a way to establish identity and it can be use in a variety of ways, such as determining twins to be identical or fraternal, and for many other family relationship identification. DNA samples can be obtained from blood, buccal swab, hair root, saliva, semen and much more. Because no two individuals with h exception of identical twins are composed of the exact same genetic profile, DNA testing is the absolute means to confirm any biological relationship in doubt.

The Chromosomal Lab Process
Results of a DNA test are often used to make life-changing decisions, either by the tested parties themselves or by those who have the authority to do so, such as a court of law or a government agency. Chromosomal Lab Process ensures that every test result we release is accurate and that our sample handling procedures hold up against rigorous legal examination.
In this process, each DNA sample that arrives in the lab is divided in two for independent testing by two teams. At each step, the samples are identified and checked against our records. A staff member signs off at each step. In this way, the samples are tracked and accounted for throughout the process. The raw data produced from the independent tests are reviewed by our laboratory directors to see if the results match. The necessary statistical calculations are then performed in order to answer questions of paternity, identity, and family relationships.

ABI 3100 and 3130 xl Genetic Analyzers
The DNA samples that our lab receives, most often buccal swabs and sometimes blood, need to undergo several DNA purification and preparation steps before the actual DNA test. The cheek or blood cells first need to be lysed to release the DNA. Secondly, proteins, fats and other cellular materials have to be removed so that they do not interfere with the DNA test. Finally, the proper amount of DNA must be added to special reagents for the DNA test. Traditionally, these steps would have been performed by a laboratory technician, sample by sample.
Each of our ABI systems allows us to perform the above DNA purification and preparation steps in batches of 384 at a time—thousands in a day. With precise and accurate liquid handling methods, these robots ensure consistency and reliability of our DNA tests. They also reduce the possibility for human error and sample mix-ups while increasing the number of DNA tests we can process each day.



ABI GeneAmp PCR System 9700
The Polymerase Chain Reaction (PCR) has revolutionized the DNA testing industry by providing a quick method for reproducing specific portions of a DNA molecule for subsequent analysis. Chromosomal Lab invested in this technology early on, and we have further refined our processes to provide seamless and faster sample processing. We use several GeneAmp PCR systems in most of our DNA tests, especially for paternity and forensics applications.

ABI Prism 7000 Real Time PCR System
Our laboratory is equipped with several ABI Prism 7000 Real Time PCR System that process the large number of cases we receive each day. The ABI Prism performs one of the most essential steps in DNA testing—capillary analysis. In this step, DNA molecules produced from PCR are examined to determine characteristics such as size or sequence (the arrangement of DNA molecules in a DNA strand). The ABI Prism generates the raw data that is needed for the statistical calculations that determine paternity, identity, and family relationships. Statistical analysis of the data is performed by one of our PhD's using the specially designed software.
