Accrediting organization for paternity testing. (Formerly known as the American Association of Blood Banks)
The recognition of 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.
This type of sample is collected using cotton-tipped applicators that are rubbed inside a person’s mouth on the inner lining of the cheek. The samples which are collected are cheek cell samples, not saliva samples. Also known as a cheek swab.
This term refers to the paper trail showing the collection, possession, control, transfer, analysis and disposition of physical evidence.
In 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:
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.
Commonly referred to as legal test.
Custody is a legal term used, most often in a divorce or separation, to describe who will have legal control and responsibility for a minor child. Legal custody may be granted to a single individual or to both parents (called joint or shared custody).
A deceased person.
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."
Is an interpretation of the test results that the tested relationship does not exist. For example, the tested man is not the biological father of the child.
A biological sibling, parent or child of an individual.
These are tables showing the distribution of different alleles for the same gene. These tables are established for each genetic marker tested that showed the frequency of each allele. They are established for each race and the frequencies are then used to calculate paternity indices.
Kinship is a connection by blood.
Related through one’s mother.
A parentage test is a biological test performed to determine whether a person is the biological parent of a child.
Related through one’s father.
A biological sample taken from a person’s body. Pathology samples are often tissue samples.
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.
The prior probability can be from 0 to 1. This is a measure of any evidence other than the test. For example, the social evidence surrounding conception. Laboratories routinely use a prior probability of 0.5, which is considered neutral. This means that the weight of the non-test evidence in favor of paternity is equal to the evidence against paternity.
A second-degree relative is a grandparent, grandchild, aunt, uncle, niece, or nephew.
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.
A surrogate mother agrees to become pregnant for the purpose of giving birth to a child for others to raise. She can be the child’s genetic mother or could have been implanted with an egg from another woman and man.
