Identity Test

DNA is a genetic substance that contains all personal genetic information, and each person has his or her own DNA pattern inherited from their parents, which distinguishes him or her from others.

• - Principle of testingDNA is a genetic substance that contains all personal genetic information, and each person has his or her own DNA pattern inherited from their parents, which distinguishes him or her from others.
  The DNA profile is the genetic information specific to a person that enables personal identification, and is the combination of gene loci featuring chain repetition. Personal identification testing is a test that examines the DNA profiles of two or more specimens to determine their agreement. For example, it performs DNA testing on the hair of an attacker found in the field and a specimen collected from a suspect to verify their identicalness. DowGene, DowGene DNA Testing Company performs analyses based on the CODIS gene locus, which is used by the FBI in the U.S.
• - Testable specimens Blood, hair with roots, oral epithelial cells, saliva, blood, toothbrushes, nails, body fluid-stained clothing, chewing gum, cigarette butts, Semen-stained tissue, tissue, etc.
• - Test Procedures Request for testing → Test collection kit shipping → Collection of specimen and acceptance of application → DNA extraction → PCR amplification → Genotype analysis and interpretation → Notification of results
• - DNA Analysis Results The identicalness is acknowledged when the genotype of all gene loci investigated through DNA testing on two specimens agree with each other. However, a disagreement founded in any gene locus indicates non-identicalness.
• - Application Cases of Personal Identification Testing
  • • When the identification of crime scene evidence such as blood, hair, semen-stained tissue, saliva, cigarette butts, nails, etc. is required
  • • When identification is required for an accident
