(formerly known as American Association of Blood Banks) Accrediting organization for paternity testing.
The recognition by an accrediting organization that the company's services consistently conform with the standards set by the accrediting organization.
A document or expert testimony is considered to be "admissible" when it is accepted as evidence in a judicial matter.
A sworn statement in writing made especially under oath or on affirmation before an authorized magistrate or officer.
A man who may be the biological father of a child.
A test where the biological specimens are collected in a non-clinical setting without the usual chain of custody procedures. Results from an at-home collection are not intended for use in legal matters. These tests are not governed by accrediting organizations.
An autopsy sample is one which is collected by a coroner or medical examiner during the examination of a body after death. Such samples usually consist of a blood sample.
Autosomal DNA is the DNA derived from all of the chromosomes (22 pairs in total) except the sex chromosomes (X & Y). A routine STR test involves the examination of a small percentage of the total autosomal DNA. The autosomal DNA examined in a DNA paternity test is non-coding, meaning that the DNA tested is not responsible for the generation of any physical characteristics of the person.
Sometimes called Birth Father or the Natural Father. The Biological Father normally contributes 50% of his DNA to the child.
This term refers to the paper trail showing the collection, possession, control, transfer, analysis and disposition of physical evidence.
For any Legal DNA case, the Chain of Custody of the sample is of utmost importance. Therefore LabCorp has developed strict procedures and systems to ensure that the procedures have been followed.
Chain of Custody involves procedures that apply to the following steps of a DNA test:
- Identification of the tested party
- Obtaining Consent
- Collection of specimens from the tested party
- Packaging of the specimens
- Shipment of the specimens
- Receipt of the specimens by the DNA laboratory
- Testing of specimens within the DNA laboratory
- Storage of the specimens
See buccal swab.
Child support is a court-ordered payment by one parent to the custodial parent of a minor child after divorce or separation of the parents.
Chromosomes are long pieces of DNA present in the nucleus of cells of living beings. A human has 46 chromosomes in total with 23 from each parent.
The Combined Paternity Index is the product of individual paternity indices at each genetic locus tested in a paternity test. The Combined Paternity Index compares the likelihood that the tested mother and alleged father produced the child versus the likelihood that the mother and a man selected at random from the population produced the child. It is a measure of the weight of the scientific evidence obtained from the test.
Parent who has custody of the child.
A complex naturally occurring organic chemical that is found in all cells. This compound is responsible for coding the genetic information that is passed on to offspring. Its acronym is "DNA."
Twins that are from two separately fertilized eggs. Also called Fraternal twins
Fraternal twins, also called dizygotic twins, occur when two separate eggs are fertizlied. Fraternal twins may be of the same sex or of two different sexes. Although unusual, it is possible that fraternal twins could have different fathers.
A "legal" test is also called a Chain of Custody or court-ready test. It is completed using DNA samples that have been collected by an unbiased third party with a documented Chain of Custody.
The plural form of locus.
The singular term for a specific location on a chromosome.
A test (usually DNA) to determine whether a woman is or is not the biological mother of a child.
Relating to descent through the maternal line.
Also called identical twins, monozygotic twins develop from a single fertilized egg that divides after it is fertilized into two separate embryos. Identical twins have DNA that is exactly the same. They will be the same sex and will look like each other.
The parent who does not have custody of the child in question.
A non-standard sample is a biological sample used for DNA testing that is not a cheek swab or blood sample.
A parentage test is a biological test performed to determine whether a person is the biological parent of a child.
A biological test performed to determine the probability that a certain man is the biological father of a child.
A biological sample taken from a person’s body. Pathology samples are often tissue samples.
Relating to descent through the paternal line.
Postmortem means after death. It can also refer to the examination of a deceased individual to determine the cause of death and will often lead to the collection of several biological samples from the deceased.
The ability of a genetic marker system to detect a man who has been falsely accused of paternity.
In the context of paternity testing, a prenatal test is one that is conducted before the birth of a child, using an amniotic fluid sample or piece of the placenta (CVS), from the fetus.
A second-degree relative is a grandparent, grandchild, aunt, uncle, niece, or nephew.
A cheek swab sample that is collected by the party to be tested. It is usually obtained in a person’s home.
A test to determine if two or more individuals are biologically related as either full or half siblings.
STR is an acronym for Short Tandem Repeat. STRs are short sections of DNA that contain a nucleotide sequence which is repeated a number of times in certain sites on specific chromosomes. The number of repeats differs from individual to individual within the population. These sections of DNA are examined in DNA identity testing.
The sex chromosome associated with female characteristics in mammals. It occurs as a pair in human females and singly in human males.
The sex chromosome that is contributed by a father to his son. Y-chromosomes are only found in males.
