iD4U

iD4U provides a personal gene identification service upon customer request. iD4U offers a paternity test that can confirm lineal ascendant relationships with a comparative analysis of the unique DNA patterns of individuals, a maternity test that can prove the maternal blood relationships of a female, DNA analysis of human remains for the identification of a person killed in a war, and personal identification testing.

There are tests to submit to a public agency to prove facts to have legal force as well as tests for general confirmation to verify facts. iD4U can perform gene analysis tests with various specimens that can be tested such as hair, epithelium cells, body remains, and saliva, providing reliable services with 99.99% accurate test results.

Test Purpose

- To prove lineal ascendant relation/paternal relation/maternal relation
- To submit to public institutions such as a court (correction of family register, acquisition of nationality, divorce, dispute about succession, etc.)
- To identify a person or verify if they are the same person
- To find a missing child or verify the blood relationship of separate families
- To prove blood ties and blood relationship with DNA from body remains of persons killed in war, etc.
- To verify the blood ties of body remains in a cemetery for those without surviving family members
- To identify a gene family tree of a family and kin
- To verify if the genes in the evidence of a crime scene matche the gene of a suspect

Paternity/Maternity Test

A paternity/maternity test is a method of testing a total of 16 short tandem repeat (STR) genes including gender chromosomes by gene amplification to confirm blood ties. STR analyzes sections where two to seven bases are repeated consecutively in a human DNA sequence. The frequency of repeated ATG, such as ATGATGATGATG, can be verified to prove paternity/maternity. Paternity/maternity is acknowledged if the test rate of father, mother and offspring is 99.999% or higher or the test rate of father (mother) and offspring is 99.9% or higher when the loci of 16 STR genes are investigated.

Paternity Test

Males have XY and females have XX gender chromosomes. Only males have the Y chromosome, and it is only passed to the son from the father. Thus, when comparing DNA to those of the parents, half matches the father’s DNA and the other half matches the mother’s DNA. Paternity is acknowledged if the rate is 99.9% or higher when the loci of 15 STR genes present in the Y chromosome are investigated.

Maternity Test

Human cells contain a small amount of mitochondrial DNA outside of the nucleus, as well as DNA present in the nucleus. During cell fertilization, sperm only delivers DNA in the nucleus to the egg, and so mitochondrial DNA cannot enter the egg. Consequently, mitochondria DNA is inherited from the mother.

Mitochondrial DNA is used to study the origin of humans, because it is inherited by son and daughter from the mother, and the daughter passes it on to her offspring. The maternity test analyzes the variation of sequences of HV1 and HV2 where many variations occur in mitochondrial DNA. Maternity is only acknowledged when three or more match.

Personal Identification Test

A personal identification test or DNA profiling is used as a gene test method during criminal investigations. iD4U analyzes the gene loci of 16 STR based on an international standard analysis method (CODIS gene loci used by the U.S. FBI), to perform the personal identification test. STR analyzes sections where two to seven bases are repeated consecutively in a human DNA sequence, and it is the same as the analysis method for the inheritance of blood types from parents.

Type AB can occur when the parents are type A and type B. During the DNA profile investigation, if the repeat frequencies of a sequence inherited from the parents are 11 and 13, it is expressed as 11/13. Among them, at least 15 sections are analyzed to verify if it is the same person.
