DNA Paternal
Analysis
The DNA Parentage testing service allows for the determination of
the true biological parent of the child. This method is highly accurate as compared to the
conventional ABO blood typing, where the result has the tendency to be tentative.
Therefore, the DNA parentage testing has become the choice of resolving the conflict of
child dispute. Additionally, DNA parental testing can be submitted as acceptable evidence
in court system today.
DNA, A Unique Structure
Deoxyribonucleic acid (DNA) structure or molecule, which is found in
every living organisms was discovered in 1953 by two noted scientists, Watson and Crick.
It is responsible for determining the physical and physiological attributes of an
organism. For example, the irresistibly bright and captivating scent of a rose flower, the
effervescent and flexible trunk of an elephant, or simply the alluring and elegant color
of the eyes. Whatever the DNA has programmed to accomplished from the beginning of life
can only be appreciated as the great artworks of Michelangelo.
DNA is a unique structure, because it remains constant for a
lifetime much like our fingerprint's geometrical line pattern is maintained without
varying in shape. DNA can be obtained from buccal cells, or various bodily fluids such as
blood, urine, synovial, etc. DNA is extracted and isolated by using an ultra speed
centrifuge (< 20,000 rpm). The identification of DNA is done by searching for matching
allele sizes from the child, father and/or mother using methods of electrophoresis or
Polymerase Chain Reaction (PCR).
DNA On Your Side - The Process
DNA analysis is often tedious and time consuming. For these reasons,
it is only done by a highly trained and experienced individual holding a Doctorate Degree
in Science. This assures high confidence in results at all times.
As with any type of scientific analysis (drug, alcohol, microbial,
etc.), collaboratively, successful accomplishment of this task begins with the
documentation of all required information and properly collecting the sample. To
facilitate and greatly reduce the burden of this imperative duty, we have devised a
protocol that is quick, simple, and highly effective. The following will help guide you,
as well as explain the process of doing parentage DNA analysis. We hoped that we could
satisfactorily serve your interest, and find this an interesting and educational
adventure.
1. Gathering Information
In order to determine parentage, the child, the father, and/or the
mother must participate. Information such as name, address, birth date, social security
number will be gathered from each participating individual. If the case has legal
implications, a fingerprint, facial photograph, and notarization of the laboratory report
are required.
2. Specimen Collection
Postnatal
To maintain quality control, specimens will be collected at our
laboratory facility. However, in situations where coming to our lab is not feasible
because of medical conditions, location, etc. specimens can also be collected in a
qualified medical facility (hospital, physicians office, laboratory, etc.). Please contact
our lab so that we can accommodate your needs.
Specimens of blood or buccal cells will be collected from each
individual. In general , a child under five years old or individuals with collapsing or
poor veins for blood draw, buccal cells can be collected by swabbing both the inner cheek
walls with a Dacron material resembling cotton.
Prenatal
In a case where there is an immediate need to determine parentage,
prenatal DNA parentage analysis is also available. Sample collection method will vary
depending on the stage of pregnancy. In general, pregnancy of time length of 10-13 weeks
and 14-24 weeks, procedures will be done by Chorionic Villi Sampling and Amniocentesis,
respectively. To arrange for prenatal specimen collection, please contact your OB/GYN
physician. We will provide all necessary forms and specimen collection kits.
